Sunbeam Snake

Xenopeltis unicolor

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The sunbeam snake is a semi-fossorial snake of South-East Asia, of a brownish black that in full light produces a spectacular iridescence: its scales break light into every colour of the rainbow. It spends the day buried and comes out at night to hunt frogs and rodents. It is the only surviving member of a very ancient family.

Fun facts

  • Its iridescence is among the most intense in the animal kingdom: microscopic layers on the surface of the scales diffract light, producing flashes of every colour of the spectrum against an almost black background.
  • It belongs to a family with only two living species, a very ancient lineage whose position in the snake family tree has been debated for decades.
  • It is common in the rice fields of South-East Asia, where it hunts rodents and frogs, and its presence is considered beneficial for the pest control it provides.
