Green is the most common coat among tree-dwelling snakes, and for good reason. Bright and olive greens blend with leaves, while browns and greys match bark and dry twigs. The green vine snake, found in parts of India and Southeast Asia, is long, thin and leaf-green, with a pointed snout that looks like a tendril. Other species, such as the emerald tree boa of South America and the green tree python of New Guinea and northern Australia, have vivid green bodies that vanish among the canopy. Some snakes, such as the eyelash viper of Central and South America, come in several colours, including yellow, orange and speckled brown, which helps them match different perches.
