Typhlophis

The genus Typhlophis is monotypic and restricted to northeastern South America. These are burrowing snakes with extremely cryptic habits, which explains their low number of records. Their most distinctive feature is the head covered with small, homogeneous scales similar to those on the rest of the body, along with an elongated, cylindrical body, very reduced eyes, and anatomy adapted to subterranean life.

These snakes are completely harmless to humans and feed mainly on small soil organisms, contributing to the regulation of these communities. Their appearance on the surface is usually accidental, generally associated with heavy rains or soil disturbance.

Although their ecological role is discreet, Typhlophis plays an important part in soil health, and its conservation depends on habitat preservation and the protection of subterranean ecosystems.
