The Atractaspididae are a family of snakes found in Africa and the Middle East. Currently, 12 genera are recognized.[1]

Description

This family includes many genera formerly classed in other families, on the basis of fang type. It includes fangless (aglyphous), rear-fanged (opisthoglyphous), fixed-fanged (proteroglyphous), and viper-like (solenoglyphous) species. Molecular and physiological data linking this family to others is ambiguous and often contradictory, which means the taxonomy of this family is highly contentious. The nominate family, Atractaspididae has itself been moved to and from other taxa, reinforcing the ambiguity of this family.

Geographic range

This family is found in Africa and the Middle East.[2][3][4]

Venom

Most of these snakes are inoffensive or far too small to envenom a person effectively. However, some can inflict severe tissue necrosis e.g. if the victim's thumb is bitten, the tip of that digit may be lost. Relapses may occur long after the bite. [5][6]

Very few deaths seem to have resulted from accidents with these snakes, although large individuals of Atractaspis microlepidota and a few other long-glanded species are very likely to be dangerous.[7] Some of the long-fanged species are able to stab their prey (or an unfortunate human) even while their mouth is closed, and the typical grasp used by herpetologists to securely hold venomous snakes is not necessarily safe for this group.[8][9] This ability to stab sideways even with a closed mouth is the basis for an English name used for some of them; side-stabbing snakes.[3]
