Typhlopidae

Typhlopidae is a family of blind snakes found across tropical and subtropical Africa, Asia, the Americas, Australia and many islands, comprising 18 genera and more than 200 species. They live underground, with vestigial eyes, a shovel-like scale over the mouth for digging, and jaws fixed in a way that limits them to prey smaller than their own mouth, mostly termites and ants. Reproduction is mostly by egg laying, though the Brahminy blind snake is a notable exception, the only known unisexual snake, with an all female population that reproduces by parthenogenesis. The family is thought to have originated in Madagascar in the Late Cretaceous before spreading across the tropics.
