The Colubridae (from Latin coluber, snake) are a family of snakes. With 304 genera and 1,938 species, they are the largest snake family, and include about two-thirds of all known living snake species. The earliest species of the family date back to the Oligocene epoch. Colubrid species are found on every continent except Antarctica.
