Atractus trilineatus, commonly known as the three-lined ground snake, is a species of small burrowing colubrid snake.[3]
Geographic range
It is found in northern South America,[4] and the Caribbean island of Trinidad.[3]
Description
Adults may attain 225 mm (8 3⁄4 in) in total length, including a short tail of 15 mm (1⁄2 in). Dorsally, they are brown with three or four darker longitudinal stripes; ventrally they are either uniform white, or have a few brown dots. The smooth dorsal scales are in 15 rows, and the anal plate is entire. Ventrals are 125-150, and subcaudals only 11-19.[5]
Diet
They are believed to feed on soft-bodied insects and earthworms,[6] as well as fish and tadpoles.[7]
