Description

edit

Most species of Leptotyphlops look much like shiny earthworms. They are generally black, grey, or blackish-brown and their scales give them a segmented appearance. Their common name comes from the fact that their eyes are greatly reduced almost to the point of uselessness, and hidden behind a protective head scale. The species which are called thread snakes are so named because of their very narrow, long bodies.

Behavior

edit

All blind snakes including those of the genus Leptotyphlops are burrowing snakes, spending most of their time deep in loose soil, typically only emerging when it rains and they get flooded out.

Diet

edit

The primary diet of Leptotyphlops is ant and termite larvae.
