Bibron's Burrowing Asp

Bibron's Burrowing Asp is a secretive, fossorial venomous snake found across southern and eastern Africa. It belongs to a unique family of burrowing asps notable for their unusual fang mechanism, allowing them to deliver a stabbing bite by protruding a single fang sideways without fully opening the mouth.

It is venomous, and its bite can cause significant local pain and swelling, though it is generally not regarded as life-threatening to healthy adults. Its sideways-stabbing fang mechanism sets it apart from most other venomous snakes.

• Cylindrical, glossy body with smooth scales
• Uniform dark brown, purplish-black, or black coloration, sometimes with a paler belly
• Small head barely distinct from the neck, tiny eyes
• Short tail with a blunt or slightly pointed tip
• Adult length typically 30-60 cm (12-24 in)

Found in savanna, woodland, and semi-arid habitats across southern and eastern Africa, often in loose or sandy soils. Spends most of its time underground or under surface debris such as logs, rocks, and leaf litter.

Fossorial and largely nocturnal, rarely seen above ground except when disturbed. Feeds primarily on other burrowing reptiles, small mammals, and amphibians. Notable for its unique defensive bite, delivered by swinging a single protruded fang sideways rather than opening the jaws widely. Reproduction is oviparous.
