Shaw's dark ground snake or Shaw's black-backed snake (Liophis melanotus) is a species of colubrid snake endemic to northern South America.[3]
Description
It grows up to a total length (body plus tail) of 43 cm (17 in).[3]
Dorsally, it has a light yellow or pinkish color, with a wide, dark vertebral stripe,[3] which is bordered on each side by a thin whitish stripe, followed by a thin dark stripe. The top of the head is olive, and there is a dark stripe passing through the eye. The upper labials and the venter (underside) of the snake are whitish.[4]
The dorsal scales are smooth, with apical pits, and are arranged in 17 rows at midbody.[4]
Behavior & diet
It actively forages during the day for food, which may include fish, amphibians, and lizards.[3]
Geographic range
Its distribution includes Colombia, Venezuela,[5] and Trinidad and Tobago. It is probably extirpated from Grenada.[3]
