Colubrids are a diverse family of snakes known as Colubridae. They are found all over the world, except in extreme environments like polar regions. Most colubrids are non-venomous, although some can deliver mild venom. They come in various sizes and colors, making them fascinating to observe in the wild. These snakes play important roles in their ecosystems, often controlling populations of small mammals and insects. Common examples of colubrids include the garter snake and the rat snake. Their adaptability and wide distribution make them one of the most successful groups of snakes on the planet.
