The Anomalepididae are a family of nonvenomous snakes, native to Central and South America. They are similar to Typhlopidae, except that some species possess a single tooth in the lower jaw. Currently, four genera and 15 species are recognized.[2] Common names include primitive blind snake[2] and dawn blind snake.



Species in the family Anomalepididae are small snakes, in total length (including tail) usually less than 30 cm (12 in), with blunt heads and short, blunt tails. They are mainly burrowing snakes, and due to their life style their eyes are vestigial.

Geographic range


The family Anomalepididae is found from Southern Central America to north-western South America. Disjunct populations occur in north-eastern and south-eastern South America.[1]
