The word "Colubridae" refers to a family of non-venomous snakes. Synonyms for this word include grass snakes, rat snakes, and whip snakes. These snakes are generally found in various parts of the world, especially in Asia, Africa, and America. They are known for their slender bodies and relatively low levels of aggression. One of the most common types of colubridae is the garter snake, which is found across North America. These snakes are harmless to humans and play an important role in many ecosystems.
