Snakes are elongated, limbless, flexible reptiles. Their body shape depends on the habitat in which they live. Aquatic snakes usually have a flattened body; those living in trees are long and slender with a prehensile tail while burrowing snakes tend to be compact. Snakes are found in a huge range of colors, from bright to dull. Brightly colored snakes are usually venomous, their coloration serving as a warning to predators, while dull colored snakes use their coloration for camouflage. Some snakes mimic the color and pattern of venomous snakes.Brahminy blind snakes are the smallest snake at two inches in length. The anaconda can reach lengths of 38 feet. In captivity, some species will live as long as 50 years.
