| | Bites Venom |
 | | In snakes, venom is an evolutionary adaptation to immobilize prey, secondarily used in defense. |
 | | Africa’s rich venomous snake fauna is dominated by true vipers (ncluding arboreal vipers, desert vipers, nightadders, puffadders, and saw-scaled vipers), terrestrial elapids, (cobras and mambas), molevipers (Atractaspidinae), and two of the world’s four deadliest colubrids, the boomslang (Dispholidus typus) and the African birdsnake (Thelotornis kirtlandii). |
 | | In proteroglyphous snakes, the fangs are short because large fixed fangs would require a deepening of the mouth cavity to prevent the fangs from perforating the floor of the mouth. |
