Atractus trilineatus, commonly known as the three-lined ground snake, is a species of small burrowing snake in the family Colubridae. The species is native to South America.[3]
A. trilineatus is found in northern South America,[4] including the Caribbean island of Trinidad.[3]
The preferred natural habitat of A. trilineatus is forest and savanna, at altitudes from sea level to 500 m (1,600 ft), but it has also been found in agricultural and horticultural areas.[1]
A. trilineatus may attain a total length of 225 mm (8+3⁄4 in), including a short tail of 15 mm (1⁄2 in). Dorsally, it is brown with three or four darker longitudinal stripes; ventrally it is either uniform white, or has a few brown dots. The smooth dorsal scales are in 15 rows, and the anal plate is entire. The ventrals number 125–150, and subcaudals only 11–19.[5]
A. trilineatus is believed to prey upon soft-bodied insects and earthworms,[6] as well as fish and tadpoles.[7]
A. trilineatus is oviparous.[3] Eggs are layed in March, May and August, and clutch size is three to five eggs.[7]
