Fattail scorpion or fat-tailed scorpion is the common name given to scorpions of the genus Androctonus, one of the most dangerous groups of scorpion species in the world.[1] The genus was first described in 1828 by Christian Gottfried Ehrenberg.[2]

Diversity
About 30 species

They are found throughout the semi-arid and arid regions of the Middle East and Africa.[1] They are moderate sized scorpions, attaining lengths of 10 cm (just under 4 in).[3] Their common name is derived from their distinctly fat metasoma, or tail, while the Latin name originates from Greek and means "man killer".[4] Their venom contains powerful neurotoxins and is especially potent.[1] Stings from Androctonus species are known to cause several human deaths each year.[1] Several pharmaceutical companies manufacture an antivenom for treatment of Androctonus envenomations.[5]

The fat-tailed scorpion is nocturnal and enjoys making nests where they hide in crevices during the day to stay moisturized. [6] One of the main threats that the scorpions face is habitat loss. [7]

Geographic range

edit

Androctonus is widespread in North and West Africa, the Middle East and eastwards to the Hindukush region. Countries where Androctonus species live including Egypt, Israel, India, Lebanon, Turkey, Jordan, Saudi Arabia, Yemen, Oman, United Arab Emirates, Qatar, Kuwait, Iraq, Iran, Afghanistan, Bahrain, Pakistan and Morocco.

Etymology

edit

A rough English translation of the name Androctonus is "man-killer", from the Ancient Greek anḗr, andrós (ἀνήρ, ἀνδρός), meaning "man" and kteínein (κτείνειν), meaning "to kill". Crassicauda means fat-tailed, from the Latin crassus meaning "fat" and cauda, meaning "tail". Androctonus crassicauda is widespread throughout the Middle East and its name means "fat-tailed man-killer". Similarly, the Latin word for South is australis, from which Androctonus australis, "southern man-killer", derives.

In captivity

Despite the risks of keeping such a dangerously venomous species in captivity, Androctonus scorpions are frequently found in the exotic animal trade,[where?] A. amoreuxi and A. australis being the most commonly available. The fat-tailed scorpion's main diet when in captivity consists of cockroaches, grasshoppers, and crickets. However, the fat-tailed scorpion is able to go months without consuming food. Scorpions will generally try to kill and eat anything which moves and is smaller than themselves.[8] Fat-tail scorpions kill their prey by first crushing them with their pincers and then injecting them with venom from their stingers.[9] Once the prey has been stung, it causes paralysis and allows the scorpion to consume it with ease.[10] Interestingly, the fat-tail scorpion can only ingest liquids.[11] To simulate the desert environment, the enclosure used to keep the scorpion in must be kept at a temperature of between 26 and 30 degrees Celsius (79–86 °F)[citation needed].
