LEPTOTYPHLOPIDAE

This family of snakes is composed of 50 species in two families. They are generally regarded as the most primitive snakes, having a pelvic girdle and vestiglial hind limbs. They have a single lung and oviduct and are well adapted to their burrowing life style. They feed exclusively on small invertebrates such as ant and termite larvae. Leptotyphlopids are oviparous. There are two species of this family in North America.
