The name Colubridae refers to a family of snakes having 304 genera and 1938 species. Coluber, in Latin, means snakes. This is the largest family of snakes, accounting for about two thirds of all snake species extant. We can trace the earliest species of the Colubridae family to the period of the Oligocene epoch. The fangs of the Colubridae are not located at the front of the mouth. They form an angle at the back. So, they also call them rear-fanged snakes. Different from the Elaipids and the vipers, the Colubrids do not have hollow fangs. They are grooved to channel venom, when they bite. You can see the species of the Colubrid family in all continents except the Antartic. Most Colubrid species are not venomous. Some possess venom that are not harmful to human beings. They are mostly harmless. A few groups like the genus Boiga can cause potent bites of medical significance. The twig snakes, the Boomslang and the Asian genus Rhabdophis have caused human deaths. We cannot call Colubridae a natural group, since many of the species are closely related to other groups like Elaipids, than to one another. The family typically has attempted to classify the snakes that are misfits elsewhere.
