Snakes are cold blooded vertebrates of the class Reptilia, order Squamata, and suborder Serpentes. These legless carnivores are covered in protective scales and have the ability to consume their prey whole. Snakes are found in a wide variety of environments on every continent except Antarctica. There are over 3,400 species of snakes, and 18 families, but most can be separated into 5 main groups: Boas, Pythons, Colubrids, Vipers and Elapids. Vipers and Elapids are venomous snakes which inject their prey with a toxin to kill them, while Boas, Python, and Colubrids kill their prey by constricting their bodies. Some Colubrids, such as Garter Snakes and Indigo Snakes, quickly consume their prey alive without constriction. Snakes have an incredible sense of smell and detect prey by flicking their tongue and catching scent particles in the air. When they bring their tongue into their mouth, they run it across their Jacobson’s Organ, which sends a signal to their brain to identify what they smell. It is important with snakes to research their natural habitat and try your best to mimic it. Some snakes live in trees in the rainforest, while others burrow in the sands of the desert. Mimicking that environment is important to a long happy life in your home.
