Chironius exoletus colubridae snake


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.

Description

Colubridae httpsuploadwikimediaorgwikipediacommonsthu

While most colubrids are not venomous (or have venom that is not known to be harmful to humans) and are mostly harmless, a few groups, such as genus Boiga, can produce medically significant bites, while the boomslang, the twig snakes, and the Asian genus Rhabdophis have caused human fatalities. Colubridae also include the few species of actually poisonous snakes, notably Rhabdophis tigrinus, the Japanese grass snake or yamakagashi, the difference between poisonous and venomous being that venom requires direct administration (i.e. intravenous injection) and poison can be administered indirectly (i.e. skin contact or ingestion).

Some colubrids are described as opisthoglyphous, meaning they have elongated, grooved teeth located in the back of the upper jaw. The opisthoglyphous dentition appears at least twice in the history of snakes. These are unlike those of vipers and elapids, which are located in the front.

Classification

The Colubridae as traditionally defined are not a natural group, as many are more closely related to other groups, such as elapids, than to each other. This family has classically been a "garbage bin taxon" for snakes that do not fit elsewhere. Additional research will be necessary to sort out the relations within this group.
