The family Colubridae consists of a diverse group of snakes, commonly known as colubrid snakes. They are found all over the world, except in extreme polar regions. Colubrids vary greatly in size, color, and habitat, making them one of the largest snake families. Most colubrids are non-venomous, although some possess mild venom that is not harmful to humans. Colubrids play essential roles in their ecosystems, often acting as both predators and prey. They primarily feed on small animals, such as rodents, birds, and lizards. Some well-known colubrid species include the garter snake and the rat snake, which are popular among snake enthusiasts and are often kept as pets.
