The Kapuas mud snake (Enhydris gyii ) is a species of snake, native to Borneo, that can change its epidermal colour spontaneously.[1]


The common name, Kapuas mud snake, refers to the Kapuas River. The specific name, gyii, is in honor of Burmese herpetologist Ko Ko Gyi.[2]

Colour change[edit]

The snake's chameleon-like behaviour was discovered accidentally in 2005 when a specimen was put in a dark bucket. The snake's skin turned pale white 20 minutes later.[3] Scientists determined the snake to be a new species belonging to the genus Enhydris.


Like all members of the subfamily Homalopsinae, the 60 inches (150 cm) long snake is mildly venomous, rear-fanged, and viviparous.
