Asian Sunbeam Snake

About the Asian Sunbeam Snake

Xenopeltis unicolor, commonly known as the sunbeam snake, common sunbeam snake or iridescent snake, is a non-venomous sunbeam snake species found in Southeast Asia and some regions of Indonesia. This is a primitive snake known for both its highly iridescent scales and its ability to reproduce quickly, as it is oviparous and as such can lay up to 10 eggs at a time. No subspecies are currently recognized.

Grows to an average of about 1 m (3 ft 3 in). The color is reddish brown, brown or blackish with an unpatterned withish-grey venter. A fossorial species, the head is wedge-shaped and narrow with little neck delineation, which makes it easy to push through the soil. Its most defining characteristic is its iridescent, highly polished scales that give this snake its common name. They have a layer of dark pigmentation just below the surface on each scale that enhances the iridescence. The young look very similar to the adults, except that they have a strong white "collar" of scales evident just below the head. This coloration fades within the first year. They have two cone opsins allowing for the potential of dichromatic color vision.
