Typhlopidae
The Typhlopidae are a family of blind snakes. They are found mostly in the tropical regions of Africa, Asia, the Americas, and all mainland Australia and various islands.〔Shine. R, 2007 Australian Snakes, a natural history, New Holland Publishers Chatswood ISBN 978-1-876334-25-3〕 The rostral scale overhangs the mouth to form a shovel-like burrowing structure. They live underground in burrows, and since they have no use for vision, their eyes are mostly vestigial. They have light-detecting black eye spots, and teeth occur in the upper jaw. The tail ends with a horn-like scale. Most of these species are oviparous. Currently, ten genera are recognized containing over 200 species.〔
==Geographic range==
They are found in most tropical and many subtropical regions all over the world, particularly in Africa, Asia, islands in the Pacific, tropical America, and southeastern Europe.〔
