Dog-faced Water Snake

A Colubrid is a snake that is a member of the Colubridae family. It is a broad classification of snakes that includes well over half of all snake species on earth. A colubrid's body is almost completely covered in scales. While most colubrids are non-venomous and are normally harmless, a few groups, such as genus Boiga, Coluber and Rhabdophis, can produce medically significant bites. In addition, the Boomslang and African Twig Snake have both caused human fatalities.The venom-injecting fangs associated with venomous colubrids are almost always in the back of the mouth, compared to vipers and elapids.
