Merge Whale and Cetacea?

I was going to make the official proposal myself, but it seems like the sort of thing that would be more skillfully discussed and handled by Team Cetacea (of which I am a fan but not a member). Krychek (talk) 20:00, 6 December 2013 (UTC)

Disagree: Since the term "whale", by usage, applies only to part of the order Cetacea, and has distinct biological differences from dolphins & porpoises, especially in the case of baleen whales, I recommend that they not be merged. AshLin (talk) 13:32, 25 August 2014 (UTC)

I don't think that partial usage is so cut-and-dried or universal to justify the current state of affairs. I'd like them both to be merged to Whale (Cetacea should be a redirect, I think.) ErikHaugen (talk | contribs) 17:53, 22 January 2015 (UTC)

Popular pages tool update

As of January, the popular pages tool has moved from the Toolserver to Wikimedia Tool Labs. The code has changed significantly from the Toolserver version, but users should notice few differences. Please take a moment to look over your project's list for any anomalies, such as pages that you expect to see that are missing or pages that seem to have more views than expected. Note that unlike other tools, this tool aggregates all views from redirects, which means it will typically have higher numbers. (For January 2014 specifically, 35 hours of data is missing from the WMF data, which was approximated from other dates. For most articles, this should yield a more accurate number. However, a few articles, like ones featured on the Main Page, may be off).

Web tools, to replace the ones at tools:~alexz/pop, will become available over the next few weeks at toollabs:popularpages. All of the historical data (back to July 2009 for some projects) has been copied over. The tool to view historical data is currently partially available (assessment data and a few projects may not be available at the moment). The tool to add new projects to the bot's list is also available now (editing the configuration of current projects coming soon). Unlike the previous tool, all changes will be effective immediately. OAuth is used to authenticate users, allowing only regular users to make changes to prevent abuse. A visible history of configuration additions and changes is coming soon. Once tools become fully available, their toolserver versions will redirect to Labs.

If you have any questions, want to report any bugs, or there are any features you would like to see that aren't currently available on the Toolserver tools, see the updated FAQ or contact me on my talk page. Mr.Z-bot (talk) (for Mr.Z-man) 04:57, 23 February 2014 (UTC)

Whale poo

Whale feces is up. Any chance of an image of whale poo? AshLin (talk) 14:20, 22 August 2014 (UTC)

Fools rush in...

... where angels fear to tread? I've begun work on Cetacean anatomy. I intend to try my best to bring in a much needed resource for our project. The whale & dolphin anatomies sections are clearly inadequate. I'm modelling the draft on fish anatomy. My draft is here. Since I'm a Wikitroll, please don't expect quick results but I hoe to get there eventually. I've done something similar in the past so hope to succeed here also.

Comment on the WikiProject X proposal

Hello there! As you may already know, most WikiProjects here on Wikipedia struggle to stay active after they've been founded. I believe there is a lot of potential for WikiProjects to facilitate collaboration across subject areas, so I have submitted a grant proposal with the Wikimedia Foundation for the "WikiProject X" project. WikiProject X will study what makes WikiProjects succeed in retaining editors and then design a prototype WikiProject system that will recruit contributors to WikiProjects and help them run effectively. Please review the proposal here and leave feedback. If you have any questions, you can ask on the proposal page or leave a message on my talk page. Thank you for your time! (Also, sorry about the posting mistake earlier. If someone already moved my message to the talk page, feel free to remove this posting.) Harej (talk) 22:47, 1 October 2014 (UTC)

Taxonomy template for auto taxobox - Order Cetartiodactlya

Hi,

I am trying to correct the taxonomy template for cetaceans. Template:Taxonomy/Cetacea/Mammalia. The Order for all cetaceans should be Cetartiodactyla Not Cetacea (which should be unranked based on current understanding); and Odontoceti and Mysticeti, which were previously suborder should be unranked. The old system should always be visible as unranked, since this is a major change in taxonomy compared to current public knowledge. I have managed to make Cetacea and the two suborders unranked in the template, but it will not allow me to make an new entry for the Order which should be Cetartiodactyla. Does anyone here have experience with the Template:Taxonomy/Cetacea/Mammalia system and who understands the classification changes I am proposing below. THANKS ShaneGero (talk) 12:54, 20 January 2015 (UTC)

Based on molecular and morphological research, the cetaceans genetically and morphologically fall firmly within the Artiodactyla (even-toed ungulates). The term Cetartiodactyla reflects the idea that whales evolved within the ungulates. The term was coined by merging the name for the two orders, Cetacea and Artiodactyla, into a single word. Under this definition, the closest living land relative of the whales and dolphins is thought to be the hippopotamuses. Use of Order Cetartiodactyla, instead of Cetacea with Suborders Odontoceti and Mysticeti, is favored by most evolutionary mammalogists working with molecular data and is supported the IUCN Cetacean Specialist Group and by Taxonomy Committee of the Society for Marine Mammalogy, the largest international association of marine mammal scientists in the world.

Extended content

Baleen whales Temporal range: Humpback whale breaching Scientific classification Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Cetartiodactyla Infraorder: Cetacea Parvorder: Mysticeti Families see cladogram Diversity 15 species Mysticeti (/ˈmɪstɪsɛtiː/), (from Latin ὁ μῦς τὸ κῆτος "the mouse, the whale so called" ), or baleen whales are a widely distributed and diverse parvorder of omnivorous, aquatic, marine mammals. They comprise the families Balaenidae (right whales), Balaenopteridae (rorqual), Eschrichtiidae (the gray whale), and Cetotheriidae (the pygmy right whale). There are currently 15 species of baleen whale. While cetaceans were historically thought to have descended from mesonychids, molecular evidence supports them as descendants of Artiodactyla (even-toed ungulates). Baleen whale split from toothed whales (Odontoceti) around 34 million years ago. Baleen whales range in size from the 6 m (20 ft) and 3,000 kg (6,600 lb) pygmy right whale to the 34 m (112 ft) and 190 t (210 short tons) blue whale, which is also the largest creature. They exhibit sexual dimorphism. Baleen whales can have streamlined or large bodies, depending on the feeding behavior, and two limbs that are modified into flippers. Though not as not as flexible and agile as seals, baleen whales can swim very fast. Baleen whales use their plates to filter out food from the water, and each genus has a different method of doing so. Baleen whales have fused neck vertebrae, and are unable to turn their head at all. Baleen whales have two blowholes. Some species are well adapted for diving to great depths. They have a layer of fat, or blubber, under the skin to keep warm in the cold water. Although baleen whales widespread, most species prefer the colder waters of the Northern and Southern Hemispheres. They spend their lives in the water, mating, giving birth, molting completely submerged, only coming to the surface to breathe. Grey whales are specialized for feeding on bottom-dwelling mollusks. Rorquals are specialized at lunge-feeding, and have a streamlined body to reduce drag while accelerating. Right whales gulp-feed, meaning they use their enlarged head to effectively take in a large amount of water and sieve the slow-moving prey. Males typically mate with more than one female (polygyny), although the degree of polygyny varies with the species. Male strategies for reproductive success vary between performing ritual displays or lek mating. Calves are typically born in the spring and summer months and females bear all the responsibility for raising them. Mothers fast and nurse their young for a relatively long period. Baleen whales produce a number of vocalisations, notably the songs of the humpback whale. The meat, blubber, baleen, and oil of baleen whales have traditionally been used by indigenous peoples of the Arctic. Once relentlessly hunted by commercial industries for these products, cetaceans are now protected by international law. However, the North Atlantic right whale is ranked critically endangered by the International Union for Conservation of Nature. Besides hunting, baleen whales also face threats from naval sonar, which result in strandings, and marine pollution. Etymology The taxonomic name "Mysticeti" (Latin, plural) apparently derives from a translation error in early copies of Aristotle's Historia Animalium, in which "ὁ μῦς τὸ κῆτος" (ho mus to kētos, "the mouse, the whale so called") was mistakenly run together as "ὁ μυστικῆτος" (ο mustikētos, "the Mysticetus"), which Rice 1998 assumed was an ironic reference to the animals' great size. An alternate name for the suborder is "Mystacoceti" (from Greek μύσταξ "moustache" + κῆτος "whale"), which, although obviously more appropriate and occasionally used in the past, has been superseded by "Mysticeti". The term "baleen" (Middle English baleyn, ballayne, ballien, bellane, etc.) is an archaic word for "whale", derived from the Latin balæna. Taxonomy Mysticeti Eschrichtius Grey whale Balaenoptera Fin whale Megaptera Humpback whale Rorqualus Bryde's whale Eden's whale Omura's whale Sei whale Pterobalaena Common minke whale Southern minke whale Eubalaena North Atlantic right whale Southern right whale North Pacific right whale Balaena Bowhead whale Cladogram showing phylogenic relations between mysticete species according to Hassanin and Ropiquet, et al. and Rosenbaum and Brownell, Jr., et al. Mysticetes are also known as baleen whales due to the presence of baleen. These animals rely on their baleen plates to sieve plankton and other small organisms from the water. Mysticetes consist of four types: Eubalaenids, rorquals, cetotheriids, and gray whales. Eubalaenids are distinguished by their enlarged head, thick blubber, and V-shaped blow, while rorquals and grey whales generally have a flat head, long throat pleats,, and more streamlined than Eubalaenids. Rorquals also tend to be larger than the latter. Two genera and nine species of rorqual are known to exist, while two genera and three species of Eubalaenid exist. Eschrichtiidae consists of only one living member: the gray whale. This animal is easily distinguished from other extant cetaceans by its sleet-grey colour, the lack of a dorsal fin, and its grey-white scars (left from parasites). Like rorquals, these use their throat pleats to increase the amount of water that can be in there at any one time to effectively filter out plankton from the water. Grey whales are bottom-feeders, meaning they sift through sand to get their food. They usually turn on their side and scoop up sediment into their mouth and filter out benthic creatures like amphipods. In addition, the two populations, one in the Sea of Okhotsk and Sea of Japan and the other in the Mediterranean Sea and East Atlantic, are thought to be genetically and physiologically dissimilar. The gray whale is traditionally placed as the only living species in its genus and family. However, DNA analysis indicates certain rorquals, such as the humpback whale, Megaptera novaeangliae, and the fin whale, Balaenoptera physalus, are more closely related to the gray whale than they are to some other rorquals, such as the minke whale. Rorquals consist of two genera (Balaenoptera and Megaptera) and nine species: the fin whale, the Sei whale, Bryde's whale, Eden's whale, the blue whale, the common minke whale, the Antarctic minke whale, Omura's whale, and the humpback whale. Rorquals are different from other mysticetes in that they use throat pleats to expand their mouth which allows them to feed more effectively. However, rorquals need to build up water pressure in order to expand their mouth, leading to a lung-feeding behavior. Lung-feeding is where a whale rams a bait ball at high speeds and opens its mouth as it hits the bait ball to reduce drag while accelerating. Rorquals generally have a streamlined physique to reduce drag in the water while foraging. In a 2012 review of cetacean taxonomy, Alexandre Hassanin and Anne Ropiquet, et al., suggested that, based on phylogenic criteria, there are 4 extant genera of rorquals. They recommend that the genus Balaenoptera be limited to the fin whale, and have minke whales fall under the genus Pterobalaena, and have Rorqualus contain the Sei whale, Bryde's whale, Eden's whale, the blue whale, and Omura's whale. Eubalaenids are also known as right whale due to whalers preferring them over other species; they were essentially the "right whale" to catch. These animals rely on their huge head, as opposed to the rorquals' throat pleats, to feed effectively. This feeding behavior allows them to grow very big and bulky, without the necessity for a streamlined body. They usually target prey large enough to be filtered through their baleen plates, and they target large baitballs. Eubalaenids consisted of two types: right whales and bowhead whales. However, recent studies done through the early 2000s reported that bowhead whales and rights whales where morphologically and phylogenically different. Cetotheriidae consists of only one living member: the pygmy right whale. This animal is easily confused with minke whales due to their similar characteristics. The pygmy right whale is very elusively seen in the wild and, consequently, little is known about its feeding behavior and much of what is known about them comes from stranded individuals. Despite its name, the pygmy right whale is more genetically to rorquals and grey whales than to other right whales, named simply because its bones resemble that of right whales. A study published in 2012 that, based on bone structure, moved the pygmy right whale from the (now empty) family Neobalaenidae to the family Cetotheriidae, making it a living fossil. Evolutionary history Restoration of Janjucetus hunderi Mysticetes split from Odontoceti (toothed whales) 34 mya during the Eocene. Their evolutionary link to archaic toothed cetaceans (Archaeoceti) remained unknown until Janjucetus hunderi was discovered in the early 1990s in Victoria. Like a modern baleen whale, Janjucetus had baleen present in its jaw and had very little biosonar capabilities. However, its jaw also contained teeth, with incisors and canines built for stabbing and molars and premolars built for tearing. These early mysticetes were exceedingly small compared to modern baleen whales, with species like Mammalodon measuring no greater than the height of three meters. It is thought that size and baleen dependence are linked. The discovery of Janjucetus and others like it suggests that baleen evolution went through several transitional phases. Llanocetus skull Llanocetus, known from the late Eocene of Seymour Island, West Antarctica, is the earliest mysticete. It is a large animal with a basilosaurid-like skull with several mysticete-like features, including a wide, flat, and dorsoventrally flattened rostrum. Its jaw had heterodont teeth separated by wide diastemata, the cheek teeth are two-rooted and palmate with accessory denticles. Additionally, fine grooves around the alveoli indicate that the palate had a rich blood supply. Llanocetus has been interpreted as a filter feeder. Other early toothed mysticeti or "archaeomysticetes" from the Oligocene are the Mammalodontidae (Mammalodon and Janjucetus) from Australia. They are small with shortened rostra, and a primitive dental formula (3.1.4.33.1.4.3). In baleen whales, enlarged oral cavities adapted for suction feeding evolved before specializations for bulk filter feeding. In the early Eocene basilosaurid Saghacetus, the mandibular symphysis is long and rigid, the rostrum is narrow, and the edges of the maxillae are thickened, indicating an adaptation for predatory feeding. In the toothed Oligocene mammalodontid Janjucetus, the symphysis is short and the oral cavity enlarged, the rostrum is wide, and the edges of the maxillae are thin, indicating an adaptation for suction feeding. The aetiocetid Chonecetus still had teeth, but the presence of a groove on the interior side of each mandible indicates the symphysis was elastic, which would have enabled rotation of each mandible, an initial adaptation for bulk feeding like in modern mysticetes. The lineages of rorquals and right whales split almost 20 mya. Is is unknown where this occurred, but it is largely thought that they, like their descendants, followed plankton migrations. These primitive mysticetes had lost their heterodont dentition in favor of baleen, and are thought to have lived on a specialized benthic, plankton, or copepod diet like modern mysticetes. Mysticetes experienced their first radiation in the mid-Miocene. Balaenopterids got bigger during this time, with species like Balaenoptera sibbaldina rivaling the blue whale in terms of size. It is thought this radiation was caused by global climate change and major tectonic activity (the Antarctic Circumpolar Current). Eomysticetes were often hunted by large sharks and killer sperm whales The first toothless ancestors of Mysticetes appeared before the first radiation in the late Oligocene. Eomysticetus and others like it showed no evidence in the skull of echolocation abilities, suggesting they mainly relied on their eyesight for navigation. The Eomysticetidae had long, flat rostra that lacked teeth and had external nares located halfway up the dorsal side of the snout. Though the palate is not well-preserved in these specimens, they are thought to have had baleen and been filter feeders. Anatomy Baleen whales vary considerably in size and shape, depending on their feeding behavior Baleen whale have two flippers on the front, near the head. The hind legs are enclosed inside the body, and are thought to be vestigial organs. However, a study done in 2014 suggests that the pelvic bone serves as support for whale genitalia. Due to their great size, baleen whales are not flexible or agile like dolphins, and none can turn their due to the fused cervical vertebrae; this sacrifices speed for stability in the water. Rorquals, needing to build speed to feed, have several adaptions for reducing drag, including a streamlined body, a small dorsal fin relative to its size, and lack of external ear or hair. While feeding, the rorqual jaw expands to a volume that can be bigger than the whale itself; to do this, the oral cavity inflates to expand the mouth. The inflation of the oral cavity causes the cavum ventrale, the folds (throat pleats) on the throat stretching to the naval, to expand, increasing the amount of water that the mouth can store. The mandible is connected to the skull by dense fibers and cartilage, allowing the jaw to swing open at almost a 90° angle. The mandibular symphysis is also fibrocartilaginous, allowing the jaw to bend which lets in more water. To prevent stretching the mouth too far, rorquals have a sensory organ located in the middle of the jaw to regulate these functions. When swimming, baleen whales rely on their flippers for locomotion in a wing-like manner similar to penguins and sea turtles. Flipper movement is continuous. While doing this, baleen whales use their tail fluke to propel themselves forward through vertical motion while using their flipper for steering, much like an otter. Some species leap out of the water, which may allow then to travel faster. Paired blowholes of a humpback and the V-shaped blow of a right whale Like all mammals, baleen whales breathe air and must surface periodically to do so. Their nostrils, or blowholes, are situated at the top of the cranium. The baleen whales have two blowholes, as opposed to toothed whales which have one. These paired blowholes are longitudinal slits that converge anteriorly and widen posteriorly, which causes a V-shaped blow. They are surrounded by a fleshy ridge that keeps water away while the whale breathes. The septum that separates the blowholes has two plugs attached to it, making the blowholes water-tight while the whale dives. When sieved from the water, food is swallowed and travels down through the esophagus where it meets a three-chambered-stomach. The first compartment is known as the fore-stomach; this is where food gets ground up into an acidic liquid, which is then squirted into the main stomach. Like in humans, the food is mixed with hydrochloric acid and protein-digesting enzymes. Then, the partly digested food is moved into the third stomach, in which fat-digesting enzymes, and then mixed with an alkaline liquid to neutralize the acid from the first stomach to prevent damage to the intestinal tract. The whale intestinal track is highly adapted to absorb the most nutrients from food; the walls are folded and contain copious blood vessels, allowing for a greater surface area over which digested food and water can be absorbed. Whales get the water they need from their food, however the salt content of most of their prey, invertebrates, are similar to that of seawater, whereas the salt content of a whale's blood is considerably lower (three times lower) than that of seawater. The whale kidney is adapted to excreting excess salt, however, while producing urine more concentrated than seawater, it wastes a lot of water which must be replaced. Senses The eyes of baleen whales are relatively small for their size and are positioned near the end of the mouth. This is probably because they feed on slow or immobile prey, and that most sunlight does not pass 30 feet (9.1 m), and hence does not need acute vision. A whale's eye is adapted for seeing both in the photic and aphotic zones by increasing or decreasing the pupil's size to prevent damage to the eye. As opposed to land mammals, whales have spherical eyeballs. The retina is surrounding by reflective layer of cells (tapetum lucidum), which bounces back at the retina, enhancing eyesight in dark areas. However, light is bent more near the surface of the eye when in air as opposed to water; consequently, they can see much better in the air than in the water. The eyeballs are protected by a thick outer layer to prevent abrasions, and an oily fluid (instead if tears) on the surface of the eye. Baleen whales appear to have limited color vision, as they lack S-cones. Humpback whale skeleton, notice how the jaw is split into two The mysticete ear is adapted for hearing underwater, where it can hear sound frequencies as low as 7 Hz and as high as 22 kHz, with the exception of the 52-hertz whale. It is largely unknown how sound is received by baleen whales. Unlike in toothed whales, sound does not pass through the lower jaw. The auditory meatus is blocked by connective tissue and an ear plug, which connects to the eardrum. The inner-ear bones are contained in the tympanic bulla, a bony capsule. However, this is attached to the skull, suggesting that vibrations passing through the bone is important. Sinuses may reflect vibrations towards the cochlea. It is known that when the fluid inside the cochlea is disturbed by vibrations, it triggers sensory hairs which send electrical current to the brain, where vibrations are processed into sound. It is largely unknown how baleen whales produce sound due to the lack of a melon and vocal cords. In a 2007 study, it was discovered that the larynx had U-shaped folds which are thought to be similar to vocal cords. They are positioned parallel to air flow, as opposed to the perpendicular vocal cords of terrestrial mammals. These may control air flow and cause vibrations. The walls of the larynx are able to contract which may generate sound with support from the arytenoid cartilages. The muscles surrounding the larynx may expel air rapidly or maintain a constant volume while diving. Baleen whales have a small, yet functional, Jacobson's organ. This allows baleen whales to detect chemical and pheromones released by their prey. It is thought that tasting the water is important for finding prey, and track down other whales. They are thought to have an impaired sense of smell due to the lack of the olfactory bulb, but they do have an olfactory tract. Baleen whales have little to no taste buds, suggesting they have lost their sense of taste. Diving adaptations Before diving, baleen whales typically stay near the surface and take 10 to 15 breaths for around three minutes and dive for eight minutes. Their unique lungs are built to collapse under the pressure instead of resisting the pressure would damage the lungs. The whale lungs are very efficient at extracting oxygen from the air, usually 80%, whereas humans only extract 20% of oxygen from inhaled air. Lung volume is relatively low compared to terrestrial mammals due to the inability of the respiratory tract to hold gas while diving. Doing so may cause serious complications such as embolism. Unlike other mammals, the lungs of baleen whales lack lobes and are more sacculated shaped. Like in humans, the left lung is smaller than the right to make room for the heart. To conserve oxygen, blood is rerouted from pressure-tolerant-tissue to internal organs, and they have a high concentration of myoglobin which allow them to hold their breath longer. Thermoregulation Baleen whales conserve heat with their large and compact body size, and insulating blubber. In addition, they have a dense network of blood vessels (rete mirabile) which prevents heat-loss. In most mammals, heat is lost in their extremities, so warm blood in arteries is surrounded by veins to prevent heat loss during transport. As well as this, heat inevitably given off by the arteries warms blood in the surrounding veins as it travels back into the core. This is otherwise known as countercurrent exchange. To counteract overheating while in warmer waters, whales reroute blood to the skin to accelerate heat-loss. Sleep Unlike most animals, whales are conscious breathers. All mammals sleep, but whales cannot afford to become unconscious for long because they may drown. They are thought exhibit unihemispheric slow-wave sleep, in which they sleep with half of the brain while the half remains active. This behavior was only documented in toothed whales until footage of a humpback whale sleeping (vertically) was shot in 2014. Behavior Baleen whales, being fully aquatic, spend their lives in the water; unable to haul themselves onto shore, they must raise young, molt, rest, and thermoregulate in the water. Several species are known to migrate vast distances, to calving grounds in tropical waters, and each species has their own breeding season. The migration cycle is repeated annually. The gray whale has the longest recorded migration of any mammal, with one travelling 14,000 miles (23,000 km) from the Sea of Okhotsk to the Baja peninsula. Foraging Humpback whales lunge-feeding All baleen whales are carnivorous and predatory. Different kinds of prey are found in different abundances depending on location, for example, Antarctic residents mostly feed on Euphausiids, however this is mainly effective for lunge-feeders, whereas gulp-feeders, like the right whales, feed primarily on copepods. Each type of whale is adapted to a specialized way of foraging. They feed solitarily or in small groups. There are two types of feeding behaviors: gulp-feeding and lunge-feeding, but some species do both depending on the type and amount of food. Baleen whales get the water they need from their food, and their kidneys excrete excess salt. Lunge-feeders are all classified under the families Balaeonopteridae (rorquals) and Cetotheriidae (pygmy right whale). To feed, lunge-feeders expand the volume of their jaw to a volume bigger than the original volume of the whale itself; to do this, the oral cavity inflates to expand the mouth. The inflation of the oral cavity causes the throat pleats to expand, increasing the amount of water that the mouth can store. Just before they ram the baitball, the jaw swings open at almost a 90° angle and bends which lets in more water. To prevent stretching the mouth too far, rorquals have a sensory organ located in the middle of the jaw to regulate these functions. They then must decelerate. This process takes a lot of mechanical work, and is only energy-effective when used against a large baitball. Gulp-feeders, or skim-feeders, are all classified under the family Balaenidae (right whales) and Eschrichtiidae (gray whale). To feed, gulp-feeders swim with an open mouth, filling it with water and prey. Prey must occur in sufficient numbers to trigger the whale's interest, be within a certain size range so that the baleen plates can filter it, and be slow enough that it cannot escape. The "skimming" may take place on the surface, underwater, or even at the ocean's bottom, indicated by mud occasionally observed on right whales' bodies. Gray whales feed primarily on the ocean's bottom, feeding on benthic creatures. Predation and parasitism Orange whale lice on a right whale Baleen whales, due to their great size, do not have any natural predators. However, calves can be preyed on by the killer whale. It is thought that annual whale migration occurs to protect the calves from the killer whales. There have also been reports of a pod attacking and killing an adult bowhead whale, holding down its flippers, covering the blowhole, ramming, and biting until dead. Generally, a mother and calf pair, when faced with the threat of a killer whale pod, will either fight or flee. The fleeing response will only occur in species that can swim away quickly: the rorquals. For the slower whales, they must fight the pod alone or with a small family group. Large sharks are another predator of whale calves. Sharks rarely attack whale calves, and there has been only one report of a shark attacking and killing a whale calf. This occurred in 2014 during the sardine run when a shiver of dusky sharks attacked a humpback whale calf. Usually, the only shark threat to a whale is getting bitten by a cookie cutter shark. Many parasites latch onto whales, notably whale lice and whale barnacles. Though not a parasite, whale barnacles latch onto the skin of a whale during its larval stage. However, in doing so it does not harm nor benefit the whale. Due to this, their relationship is often labeled as an example of commensalism. Almost all species of whale lice are specialized towards a certain species of whale, and there can be more than one species per whale. Whale lice eat dead skin, resulting in minor wounds in the skin. Whale louse infestations are especially evident in right whales, where colonies propagate on their callosities. A species of copepod, Balaenophilus unisetus, inhabits baleen plates of whales in tropical waters. A species of Antarctic diatom, Cocconeis ceticola, forms a film on the skin, which takes a month to develop. They are also plagued by internal parasites such as stomach worms, cestodes, nematodes, liver flukes, and acanthocephalans. Reproduction Female right whale with calf Before reaching adulthood, baleen whales grow at an extraordinary rate. In the blue whale, the largest species, the fetus grows by some 100 kg (220 lb)/day just before delivery, and by 80 kg (180 lb)/day during suckling. Before weaning, the calf increases its body weight by 17 t (17 long tons; 19 short tons) and grows from 7–8 m (23–26 ft) at birth to 13–16 m (43–52 ft) long. When it reaches sexual maturity after 5–10 years, it will be 20 to 24 m (66 to 79 ft) long and possibly live as long as 80–90 years. Calves are born precocial, needing to be able to swim to the surface at the moment of its birth. The same life pattern can be seen in other balaenopterids; they mate in warm waters in winter to give birth almost a year later. A 7– to 11-month lactation period is normally followed by a year of rest before mating starts again. Adults normally start reproducing when 5–10 years old and reach their full length after 20–30 years. In the smallest balaenopterid, the minke whale, 3 m (9.8 ft) calves are born after a 10-month pregnancy and weaning lasts until it has reached about 5–5.5 m (16–18 ft) after 6–7 months. Unusual for a baleen whale, female minkes (and humpbacks) can become pregnant immediately after giving birth; in most species, there is a 2-to-3-year calving period. In right whales, the calving interval is usually 3 years. Bowheads grow very rapidly during their first year, after which they hardly increase in size for several years. They reach sexual maturity when 13–14 m (43–46 ft) long. Some 19th-century harpoons found in harvested bowheads indicate this species can live more than 100 years. Baleen whales are K-strategists, meaning they raise one calf at a time, have a long life-expectancy, and a low infant mortality rate. Intelligence Unlike their toothed whale counterparts, baleen whales are hard to study due to their immense size. Intelligence tests such as the mirror test cannot be done as they have done in dolphins, because their bulk and lack of body language makes a reaction impossible to be definitive. However, studies on the brains of humpback whales revealed spindle cells, which, in humans, control theory of mind. Due to this, it is thought that baleen whales, or at least the humpback whale, have animal consciousness. Relationship with humans Whaling World population graph of blue whales Whaling by humans has existed since the Stone Age. Ancient whalers used harpoons to spear the bigger animals from boats out at sea. People from Norway started hunting whales around 2000 B.C., and people from Japan began hunting whales in the Pacific at least as early. Whales are typically hunted for their meat and blubber by aboriginal groups; they used baleen for baskets or roofing, and made tools and masks out of bones. The Inuit hunted whales in the Arctic Ocean. The Basques started whaling as early as the 11th century, sailing as far as Newfoundland in the 16th century in search of right whales. 18th and 19th century whalers hunted down whales mainly for their oil, which was used as lamp fuel and a lubricant and baleen or whalebone, which was used for items such as corsets and skirt hoops, The most successful whaling nations at this time were Holland, Japan, and the United States. Commercial whaling was historically important as an industry well throughout the 17th, 18th and 19th centuries. Whaling was at that time a sizeable European industry with ships from Britain, France, Spain, Denmark, the Netherlands and Germany, sometimes collaborating to hunt whales in the Arctic, sometimes in competition leading even to war. By the early 1790s, whalers, namely the Americans and Australians, mainly focused efforts in the South Pacific where they mainly hunted right whales, with catches of up to 39,000 right whales by Americans alone. By 1853, U.S. profits turned to USD11,000,000, equivalent to USD348,000,000 today, the most profitable year for the American whaling industry. Commonly exploited species included North Atlantic right whales, bowhead whales, which were mainly hunted by the Dutch, common minke whales, blue whales, and gray whales. The scale of whale harvesting decreased substantially after 1982 when the International Whaling Commission (IWC) placed a moratorium which set a catch limit for each country, excluding aboriginal groups until it was updated to include them in 2004. Current whaling nations are Norway, Iceland, and Japan, despite their joining to the IWC, as well as the aboriginal communities of Siberia, Alaska, and northern Canada. Subsistence hunters typically use whale products for themselves and depend on them for survival. National and international authorities have given special treatment to aboriginal hunters since their methods of hunting are seen as less destructive and wasteful. This distinction is being questioned as these aboriginal groups are using more modern weaponry and mechanized transport to hunt with, and are selling whale products in the marketplace. Some anthropologists argue that the term "subsistence" should also apply to these cash-based exchanges as long as they take place within local production and consumption. In 1946, the IWC placed a moratorium, limiting the annual whale catch. Conservation and management issues As of 2013, International Union for Conservation of Nature (IUCN) recognizes 15 mysticete species. One species—the North Atlantic right whale—is endangered with only around 400(±50) individuals left, and four more are also considered as Endangered" (North Pacific right whale, the blue whale, the fin whale, and the Sei whale), and another 5 ranked as Data deficient (Bryde's whale, Eden's whale, Omura's whale, Southern minke whale, and pygmy right whale). Species that live in polar habitats are vulnerable to the effects of recent and ongoing climate change, particularly declines in sea ice, as well as ocean acidification. The whale watching industry and anti-whaling advocates argue that whaling catches "friendly" whales that are curious about boats, as these whales are the easiest to catch. This analysis claims that once the economic benefits of hotels, restaurants and other tourist amenities are considered, hunting whales is a net economic loss. This argument is particularly contentious in Iceland, as it has among the most-developed whale-watching operations in the world and the hunting of minke whales resumed in August 2003. Brazil, Argentina and South Africa argue that whale watching is a growing billion-dollar industry that provides more revenue than commercial whaling would provide. Peru, Uruguay, Australia, and New Zealand also support proposals to permanently forbid whaling South of the Equator, as Indonesia is the only country in the Southern Hemisphere with a whaling industry. Anti-whaling groups claim that developing countries which support a pro-whaling stance are damaging their economies by driving away anti-whaling tourists. Protests of Japan's scientific whaling Commercial whaling was historically important for world economy. All species were exploited, and as one type's stock depleted, another type was targeted. The scale of whale harvesting decreased substantially through the 1960's as all whale stocks had been depleted, and practically stopped in the 1988 after the International Whaling Commission placed a moratorium which banned whaling for commercial use. Several species that were commercially exploited have rebounded in numbers; for example, gray whales may be as numerous as they were prior to whaling, making it the first marine mammal to be taken off the Endangered species list. The Southern right whale was hunted to near extinction in the mid-to-late 20th century, with only a small (unknown) population around Antarctica. Due to international protection, the Southern right whale's population has been growing 7% annually since 1970. Conversely, the eastern stock of North Atlantic right whale was extirpated from much of its former range, which stretched from the coast of North Africa to the North Sea and Iceland; it is thought that the entire stock consists of only ten individuals, making the eastern stock functionally extinct. Baleen whale continue to be harvested. However, only three nations take whales: Iceland (despite being a member of the IWC), Norway, and Japan. Iceland and Norway were part of the IWC, but withdrew in 1992 and 1993, respectively, and continued hunting minke whales; despite Iceland's rejoining in 2006, they still continue to catch whales. Japan, being part of the IWC, whales under the Scientific Permit stated in Article VIII in the Convention for the Regulation of Whaling. Japan has had two main research programs: JARPA and JARPN. JARPN is focused in the North Pacific and JARPA around the Antarctic. JARPA mainly caught Antarctic minke whales, catching nearly 7,000; to a far lesser extent, they also caught fin whales. Animal-rights activist groups (such as the Greenpeace) object to Japan's scientific whaling, with some calling a substitute for commercial whaling. In 2014, the United Nations judicial branch banned the taking of whales for any purpose in the Southern Ocean Whale Sanctuary, however Japan refuses to stop whaling and has only promised to cut their annual catches by a third (around 300 whales per year). The remains of a North Atlantic right whale after it collided with a ship propeller Baleen whales can also be effected by humans in more indirect ways. For species like the North Atlantic right whale, which migrates through some of the world's busiest shipping lanes, the biggest threat is from being struck by ships. The Lloyd's mirror effect results in low frequency propeller sounds not being discernible near the surface, where most accidents occur. Combined with spreading and acoustic shadowing effects, the result is that the whale is unable to hear an approaching vessel before it has been run over or entrapped by the hydrodynamic forces of the vessel's passage. The ever-increasing amount of ocean noise, including sonar, drowns out the vocalizations produced by whales, notably in the blue whale which produces the loudest vocalization, which makes it harder for them to communicate. Blue whales stop producing foraging D calls once a mid-frequency sonar is activated, even though the sonar frequency range (1–8 kHz) far exceeds their sound production range (25–100 Hz). Poisoning from toxic substances such as Polychlorinated biphenyl (PCB) is generally low due to their low trophic level. Some baleen whales can become victims of bycatch, which is especially serious for North Atlantic right whales, considering there are only 450 left. Right whales feed with wide-open mouths, risking entanglement in any rope or net fixed in the water column. Rope wraps around their upper jaws, flippers and tails. Some are able to escape, but others remain tangled. If observers notice, they can be successfully disentangled, but others die over a period of months. Other whales, such as humpback whales, can also be entangled. In captivity Baleen whales have rarely been kept in captivity. Their large size and appetite make them expensive creatures to maintain. Pools of proper would also be very expensive to build. For example, a single gray whale calf would need to eat 475 pounds (215 kg) of fish per day, and the pool would have to accommodate the 13-foot (4.0 m). Only two species have survived being kept in captivity for over a year before being released: gray whales and minke whales. The first gray whale, who was captured in Scammon's Lagoon, Baja California, in 1965, was named Gigi and died two months later from an infection. The second gray whale, who was captured in the same lagoon Gigi was from, in 1971, was named Gigi II and was released a year later after becoming too big. The last gray whale, J.J., beached herself in Marina del Rey, California where she was rushed to SeaWorld San Diego and, after 14 months, was released because she got too big to take care of. J.J. was the largest creature to be kept in captivity. The Mito Aquarium in Numazu, Shizuoka (Japan) housed three minke whales in a sea-gate enclosed by nets. One survived for three months, another (a calf) survived for two weeks, and another was kept for a year before breaking through the nets. References Further reading Kemper, Catherine (2008).

Interesting scope of article

I came across Whales in Ghanaian waters and am wondering if such formulations exist elsewhere: "Birds of X islands" or "Fish of Y lake". Or whether it is worth creating "Whales (or cetaceans) of Z waters". Carbon Caryatid (talk) 21:28, 22 April 2018 (UTC)

it looks like that article was specifically created because of some stranding event   User:Dunkleosteus77 |push to talk  22:41, 22 April 2018 (UTC)

We have some "Fauna of place X" and "Mammals of place X" articles, e.g. Fauna of Australia. And we have Category:Lists of mammals by location.

WikiProject collaboration notice from the Portals WikiProject

The reason I am contacting you is because there are one or more portals that fall under this subject, and the Portals WikiProject is currently undertaking a major drive to automate portals that may affect them.

Portals are being redesigned.

The new design features are being applied to existing portals.

At present, we are gearing up for a maintenance pass of portals in which the introduction section will be upgraded to no longer need a subpage. In place of static copied and pasted excerpts will be self-updating excerpts displayed through selective transclusion, using the template {{Transclude lead excerpt}}.

The discussion about this can be found here.

Maintainers of specific portals are encouraged to sign up as project members here, noting the portals they maintain, so that those portals are skipped by the maintenance pass. Currently, we are interested in upgrading neglected and abandoned portals. There will be opportunity for maintained portals to opt-in later, or the portal maintainers can handle upgrading (the portals they maintain) personally at any time.

Background

On April 8th, 2018, an RfC ("Request for comment") proposal was made to eliminate all portals and the portal namespace. On April 17th, the Portals WikiProject was rebooted to handle the revitalization of the portal system. On May 12th, the RfC was closed with the result to keep portals, by a margin of about 2 to 1 in favor of keeping portals.

There's an article in the current edition of the Signpost interviewing project members about the RfC and the Portals WikiProject.

Since the reboot, the Portals WikiProject has been busy building tools and components to upgrade portals.

So far, 84 editors have joined.

If you would like to keep abreast of what is happening with portals, see the newsletter archive.

If you have any questions about what is happening with portals or the Portals WikiProject, please post them on the WikiProject's talk page.

Thank you.    — The Transhumanist   07:28, 30 May 2018 (UTC)

Two for one for Bryde's whale and Minke whale?

There are only two articles in WikiProject Cetaceans that use manual {{taxobox}}es: Bryde's whale and Minke whale. Both are cramming two species into taxoboxes meant for one taxon each. Are both/either of these whales species complexes, or some other infrageneric clades? If so, the manual {{Taxobox}}es should be upgraded to {{Automatic taxobox}}es. If they are only evolutionary grades, then an automated {{paraphyletic group}} box should be used. I think either change could be applied without rocking the boat on the rest of the article.

I have raised this on Talk:Bryde's whale#Is it a grade or a clade? and Talk:Minke whale#Are Minke whale even a taxon or an informal grouping?, but thought I should ping here to loop in more folks. I posted separately also in case the answers are different for each article. --Nessie (talk) 19:01, 13 February 2019 (UTC)

User script to detect unreliable sources

Main page: User:Headbomb/unreliable

I have (with the help of others) made a small user script to detect and highlight various links to unreliable sources and predatory journals. Some of you may already be familiar with it, given it is currently the 39th most imported script on Wikipedia. The idea is that it takes something like

• John Smith "Article of things" Deprecated.com. Accessed 2020-02-14. (John Smith "[https://www.deprecated.com/article Article of things]" ''Deprecated.com''. Accessed 2020-02-14.)

and turns it into something like

• John Smith "Article of things" Deprecated.com. Accessed 2020-02-14.

It will work on a variety of links, including those from {{cite web}}, {{cite journal}} and {{doi}}.

The script is mostly based on WP:RSPSOURCES, WP:NPPSG and WP:CITEWATCH and a good dose of common sense. I'm always expanding coverage and tweaking the script's logic, so general feedback and suggestions to expand coverage to other unreliable sources are always welcomed.

Do note that this is not a script to be mindlessly used, and several caveats apply. Details and instructions are available at User:Headbomb/unreliable. Questions, comments and requests can be made at User talk:Headbomb/unreliable.
