1. Sunbeam Snake
The sunbeam snakes are the sole genus of the monotypic family Xenopeltidae, the species of which are found in Southeast Asia. Sunbeam snakes are known for their highly iridescent scales. The dorsal color pattern is a reddish-brown, brown, or blackish color. The belly is an unpatterned whitish-gray. Adults can grow up to 1.3 m (51 in) in length. The head scales are made up of large plates much like those of the Colubridae, while the ventral scales are only slightly reduced. These snakes are fossorial, spending much of their time hidden.
