Mortal poison: Understanding Snake Venom and How It Works

Venomous snakes of the family Colubridae have a single open canal on each fang which serves as a passageway for venom. Venomous colubrids typically have fixed rear fangs and chew their prey while injecting venom. Colubrid venom tends to have less harmful impacts on humans than the venom of elapids or vipers. However, venom from the boomslang and twig snake has resulted in human deaths.
