The Atractaspididae (atractaspidids) are a family of venomous snakes found in Africa and the Middle East, commonly called mole vipers, stiletto snakes, or burrowing asps. Currently, 12 genera are recognized.

Description This family includes many genera formerly classed in other families and subfamilies, on the basis of fang type. It includes fangless (aglyphous), rear-fanged (opisthoglyphous), fixed-fanged (proteroglyphous), and hinge-fanged (solenoglyphous) species. Early molecular and physiological data linking this subfamily to others were ambiguous and often contradictory, which means the taxonomy of this subfamily has been highly contentious. The nominate family, Atractaspididae, has itself been moved to and from other taxa, such as potentially forming a trichotomy with Elapidae and Colubridae, reinforcing the ambiguity of this subfamily.

Venom Many of these snakes are inoffensive or far too small to envenomate 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.Archived at Ghostarchive and the Wayback Machine: Archived at Ghostarchive and the Wayback Machine: The bites of stiletto snakes are often exceptionally painful.

Very few deaths have resulted from accidents with these snakes, although large individuals of Atractaspis microlepidota and other long-glanded species are very likely to be dangerous.Atractaspididae at the TIGR Reptile Database Some of the long-fanged species are able to stab their prey (or an unfortunate human) even while their mouths are closed, and the typical grasp used by herpetologists to securely hold venomous snakes is not safe for this group. 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" or "side-stabbers".
