Fattail scorpion
One of the most dangerous groups of scorpion species worldwide.
Fattail scorpion, or fat-tailed scorpion, is the common name for scorpions of the genus Androctonus, one of the most dangerous groups of scorpion species worldwide. Their venom contains powerful neurotoxins, and their sting can cause several human deaths each year, leading pharmaceutical companies to manufacture antivenom for treatment of Androctonus envenomations.

Lore & Background
Its common name derives from the distinctly fat metasoma, or tail, while the scientific name originates from Greek to mean 'man killer.' Members of this genus are moderate sized scorpions, some attaining lengths of 10 cm. They are nocturnal and hide in crevices during the day, which may also limit dehydration. Ongoing threats include habitat loss through human development.
Reader's Guide
The fat-tailed scorpion is significant for its potent venom, which contains powerful neurotoxins and can cause several human deaths each year, as well as negative effects on domestic animals. This danger has led several pharmaceutical companies to manufacture antivenom for treatment of Androctonus envenomations. Despite the risks, Androctonus scorpions are frequently found in the exotic animal trade, with A. amoreuxi and A. australis being the most commonly available. Their diet in captivity consists of cockroaches, grasshoppers, and crickets, though they can go months without food. They kill prey by crushing with pincers and injecting venom, which causes paralysis. The scorpion can only ingest liquids. Enclosures must be kept at 26–30 °C to simulate the desert environment.

Frequently Asked Questions
What is a Fattail scorpion?
The Fattail scorpion is the common name for scorpions of the genus Androctonus, a group that can reach roughly 10 cm in length and is regarded as one of the most lethal scorpion lineages on the planet. They are native to arid zones stretching from northern Africa through the Middle East into northeastern India.
Why is it called a "Fattail" scorpion?
The nickname refers to the genus's unusually thick metasoma, the segmented tail section that carries the stinger. That swollen, bulbous tail is the most visually distinctive feature that separates Androctonus from many other scorpion families.
How dangerous is a Fattail scorpion sting to humans?
The venom is loaded with powerful neurotoxins and the genus is responsible for multiple human fatalities every year. Because of this, pharmaceutical companies produce dedicated antivenom specifically for treating Androctonus envenomations.
What does the scientific name Androctonus actually mean?
It comes from the Greek words anḗr (man) and kteínein (to kill), so the name essentially translates to "man killer." The label underscores the genus's well-documented history of causing serious and sometimes fatal stings in people.
Where do Fattail scorpions live in the wild?
Androctonus species occupy a wide band of dry and semi-arid terrain, spanning northern Africa, the Middle East, and reaching as far east as northeastern India. Their preference for hot, arid habitats makes them a common and dangerous encounter in those regions.
