Largest body part

(Redirected from Heaviest brain)

The largest body part is either the largest given body part across all living and extinct organisms or the largest example of a body part within an existing species. The largest animals on the planet are not the only ones to have large body parts, with some smaller animals actually having one particularly enlarged area of the body.

As the largest animal that has existed, the blue whale has the largest instance of several body parts.

  • Its tongue weighs around 2.7 tonnes (3.0 short tons; 2,700 kg).[1]
  • Its mouth is large enough to hold up to 90 tonnes (99 short tons; 90,000 kg) of food and water.[2]
  • Its heart typically weighs 600 kg (1,300 lb; 0.66 short tons)[1] and can reach 900 kg (2,000 lb; 0.99 short tons) in exceptional cases[3]
  • Its aorta is about 23 centimetres (9.1 in) in diameter.[4]
  • The blue whale's penis typically measures 2.5 metres (8 ft 2 in) to 3 metres (9.8 ft) and a diameter of 30 centimetres (12 in) to 36 centimetres (14 in).[5]

Other animals

edit
 
Giraffes are instantly recognisable for their long necks.
  • The giant and colossal squids have the largest recorded eyes of any living animal, with a maximum diameter of at least 27 cm (11 in).[6] Only the extinct ichthyosaurs are known to have had larger eyes.[6]
  • The giraffe has the longest neck of any land mammal.[7]
  • The north Pacific right whale has the largest testes of any mammal.[8]
  • The walrus has the largest baculum of any mammal.[9]
  • The wandering albatross has the largest wingspan at 3.63 metres (11 feet 11 inches).[10]
  • The longest horns ever recorded belonged to a wild water buffalo and measured 4.24 metres (13 feet 11 inches) from tip to tip.[11]
  • The largest and heaviest brain belongs to the sperm whale, weighing around 9 kilograms.[12]
  • The Arctic lion's mane jellyfish may be the longest animal; the biggest had a bell (body) with a diameter of 2.28 meters (7 feet 6 inches) and the tentacles reached 36.6 m (120 ft). It was found washed up on the shore of Massachusetts Bay in 1870.[13]
  • Bootlace worms can reach great lengths. A specimen was measured at 55 m (180 ft) but this may be unreliable as the body is somewhat elastic.[14]

In proportion to body size

edit
  • The Morgan's sphinx hawk moth has the longest proboscis in relation to its body size. Its 25–30 cm proboscis is over 3 times longer than its body. It is also known as Darwin's moth because Charles Darwin predicted its existence some 40 years before it was discovered from experiments he did on an orchid with a "foot long" nectary.[15]
  • The tube-lipped nectar bat has the longest tongue of any mammal in relation to its body size. Its 85 mm (3.3 in) tongue is 1.5 times longer than its body, and must be kept inside its rib cage.[16]
  • The barnacle is the creature with the largest penis as a proportion of its body size.[17]
  • Among vertebrates, the Argentine blue-bill duck has the longest penis in relation to its body size.[18]
  • The vampire squid has the largest eyes of any animal relative to its size.[19]
  • The kiwi lays the largest egg of any bird relative to its size – up to a quarter of the mass of the female.
  • Viperfish have the largest teeth of any fish relative to its size.
  • Shrews have the largest brain-to-body mass ratio of any animal, with brains that are 10% of body weight. Humans however have the largest encephalization quotient of any animal.[20]
  • Dogs have the largest heart-to-body mass ratio.[21]
  • The jerboa has the largest ear as a proportion of its body size.[22]

Individual human records

edit
  • The person with the longest tongue is Nick Stoeberl of Salinas, California, United States, whose tongue measures 10.1 centimetres (3.98 in).[29]
  • The woman with the longest legs is Maci Currin. At a height of 208.28 cm (6.83 ft), her legs measure 134.78 centimetres (53 in).[30]
  • The woman with the longest fingernails is Lee Redmond. The total length of her fingernails is 7.513 meters.[31] The person with the longest fingernails on one hand is Shridhar Chillal,[32] the woman with the longest fingernails on one hand is Ayanna Williams.[33]
  • The longest head of hair belonged to Xie Qiuping of China and measured 5.627 metres (18 feet 5.5 inches) on 8 May 2004.[34]
  • The longest beard ever measured belonged to Hans Langseth of Norway; at his death in 1927 it was 5.33 metres (17.5 ft) long.[35][36]
  • The longest ear hair belongs to Victor Anthony of India, measuring 18.1 centimetres (7.12 inches).[37]
  • The largest feet belonged to Matthew McGrory. His left foot measured 17 inches (43 cm) and he wore size 29 1/2 shoes.[38]
