cyclops snake

A rare, small, non-venomous burrowing snake of the genus Achalinus (especially Achalinus spinalis or related odd-scaled snakes), native to the damp mountain forests of East and Southeast Asia and characterized by iridescent, non-overlapping keeled scales and diminutive eyes.

Any snake born with cyclopia, a rare congenital craniofacial malformation in which the embryonic prosencephalon fails to divide the orbits of the eye into two cavities, resulting in a single, centrally located eye.
