- Common names: sunbeam snakes.[2]
The Xenopeltidae are a monotypic family of snakes created to the genus Xenopeltis, which is found in Southeast Asia. Its members are known for their highly iridescent scales. Currently, two species are recognized and no subspecies.[3]

Adults grow up to 1 m in length or slightly longer. The head scales are made up of large plates much like those of the Colubridae, while the ventral scales are only slightly reduced. Pelvic vestiges are not present.[4]
The dorsal color pattern is a reddish brown, brown, or blackish color. The belly is an unpatterned whitish-gray.[5] The scales are highly iridescent, creating a beautiful display of colors in the light.[4]
These snakes are fossorial, spending much of their time hidden. They emerge at dusk to actively forage for frogs, other snakes, and small mammals.[5]
Found in Southeast Asia from the Andaman and Nicobar Islands, east through Myanmar to southern China, Thailand, Laos, Cambodia, Vietnam, the Malay Peninsula and the East Indies to Sulawesi, as well as the Philippines.[1]

T) Type species.[1]
These snakes are not very commonly kept as pets because of their high mortality rate in captivity. Shipping and the first six months in captivity are very stressful and often kill captive snakes. They also have very little tolerance of handling, with the resulting stress leading to premature death. Captive specimens should be provided with a temperature gradient and a substrate that is easy to burrow in. The cage should be kept warm, but not hot, and they should be left alone.
