The Vampire Bat (Phyllostomatidae) is a large family of about 150 species of bat distinguished by a well developed 'leaf' above the nose, or by skin folds or warts beneath the chin. The middle finger of the wing has three joints. Vampire Bats are confined to the tropical and sub-tropical regions of the world where they live in forest areas feeding on fruit and insects, although two species, Desmodus and Diphylla are blood sucking.
