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]
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]
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.
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.
Taxonomic reclassification is ongoing, sources tending to disagree on the number of species.
Androctonus Ehrenberg, 1828 (30 species):
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 ].
The Buthidae are the largest family of scorpions, containing about 100 genera and 1339 species as of 2022. A few very large genera are known, but a high number of species-poor or monotypic ones also exist. New taxa are being described at a rate of several new species per year. They have a cosmopolitan distribution throughout tropical and subtropical environments worldwide. Together with four other families, the Buthidae make up the superfamily Buthoidea. The family was established by Carl Ludwig Koch in 1837.
Tityus is a large genus of thick-tailed scorpions, the namesake of its subfamily Tityinae. As of 2021, Tityus contains more than 220 described species distributed in Central America and South America, from Costa Rica to Argentina. Species in the genus Tityus have been studied for hundreds of years, long before the taxonomic classification was put in place. Tityus tend to be of medium size for scorpions, roughly 50 to 70 millimeters long. They are dark brown or red in color, and can exhibit sexual dimorphism. They can live in a variety of environments, ranging from urban to arid mountains to the Amazon Rainforest. Tityus scorpions are best known for their venom and potent sting. The genus contains several dangerously venomous scorpions, the best known of which is the Brazilian yellow scorpion, T. serrulatus. Its venom can cause severe illness, and in the young, old and infirm even death. Some experts have argued that the genus as a whole may be paraphyletic, which could explain the knowledge gaps related to Tityus.
Androctonus maroccanus is a species of scorpion of the family Buthidae. Along with other members of the genus Androctonus it is also known by the collective vernacular name fat-tailed scorpion. A. maroccanus is endemic to the Atlantic coast of central Morocco.
Buthacus is a genus of scorpion of the family Buthidae. It is distributed across northern and western Africa, Israel, Palestine, Jordan, Syria, the Arabian Peninsula, Iraq, Iran, Afghanistan, and Pakistan.
The taxonomy of scorpions deals with the classification of this predatory arthropod into 13 extant families and about 1,400 described species and subspecies. In addition, 111 described taxa of extinct scorpions are known.
Hottentotta is a genus of scorpions of the family Buthidae. It is distributed widely across Africa, except for most of the Sahara desert. Species in the genus also occur in the Middle East, the Arabian Peninsula, southeastern Turkey, Iraq, Iran, Afghanistan, Pakistan, India, Nepal, Cape Verde Islands, and Sri Lanka (introduced).
Heterometrus, whose members are also known by the collective vernacular name Asian Forest Scorpion, is a genus of scorpions belonging to the family Scorpionidae. It is distributed widely across tropical and subtropical southeastern Asia, including Indonesia, Brunei, Malaysia, Myanmar, Philippines, Singapore, Cambodia, Laos, Thailand, Vietnam, India, and China (Hainan). It is notable for containing some of the largest living species of scorpions.
Leiurus is a genus of scorpion of the family Buthidae. The most common species, L. quinquestriatus, is also known under the common name Deathstalker. It is distributed widely across North Africa and the Middle East, including the western and southern Arabian Peninsula and southeastern Turkey. At least one species occurs in West Africa.

Androctonus bicolor, the black fat-tailed scorpion, is a scorpion species of the family Buthidae. It is black in color and can grow up to 8 cm. Black fat-tailed scorpions come from the family Buthidae, which is the largest of the scorpion family. They can be identified by their hefty physique. They tend to move very fast, and are of an aggressive nature. Black fat–tailed scorpions can live for up to 5 years. Adults can reach up to 40-60 millimeters, 80 millimeters being the maximum. These scorpions typically possess black and brown coloration. These scorpions enjoy making scrapes with wood and rocks, and are nocturnal, thus they hide in crevices or certain objects during the day. They stay in shade to retain moisture in their bodies, as they are susceptible to losing moisture due to their environmental preference.
Androctonus australis, the yellow fat-tailed scorpion, is a hardy desert scorpion from North Africa, Somaliland, the Middle East, Pakistan and India.
