Xenodon 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. While most colubrids are non-venomous (or have venom that isn't known to be harmful to humans) and are normally harmless, a few groups, such as genus Boiga and sub-family Homalopsinae, can produce medically significant bites. In addition, the African Boomslang and African Twig Snake have both caused human fatalities.

Examples of snakes found in the colubridae family include:

• Garter Snake
• Indigo snake
• King Snake
• Rat Snake
• Smooth Snake
• Water Snake
• Mussurana
