Vampire bats are members of the New World Leaf-nosed bats, the Phyllostomidae. All three species of living vampire bats occur in South and Central America. Fossils of three other species reveal that several thousand years ago vampire bats were more widespread.
Vampire bats made news earlier this week when researchers reported that these bats are able to find blood through a heat-detecting molecule covering nerve endings on their noses. According to ScienceDaily, once an adult vampire bat has found a vein to feed on, it can drink half of its body weight in blood.
