Wildlife
Common vampire bats need to feed on blood almost daily to avoid starvation. They are are not the fearsome, blood-sucking creatures portrayed in the movies, however, but rather ordinary-looking, medium-sized bats with a highly evolved feeding method. They don't actually suck blood, but lap it up from cuts made by their razor-sharp incisors. A chemical in the saliva stops the victim's blood clotting and numbs the wound. Vampire bats live in large colonies in Central and South America where they feed mostly from the abundant livestock.

The common vampire bat (Desmodus rotundus) is a small, leaf-nosed bat native to the Americas. It is one of three extant species of vampire bat, the other two being the hairy-legged and the white-winged vampire bats. These species are the only parasitic mammals. The common vampire bat mainly feeds on the blood of livestock, approaching its prey at night while they are sleeping. It uses its razor-sharp teeth to cut open the skin of its hosts and laps up their blood with its long tongue. The species is highly polygynous, and dominant adult males defend harems of females. It is one of the most social of bat species with a number of cooperative behaviors such as alloparenting, social grooming and food sharing. Because it feeds on livestock and is a carrier of rabies, the common vampire bat is considered a pest. Its conservation status is categorized as Least Concern by the International Union for Conservation of Nature (IUCN) because of "its wide distribution, presumed large population tolerance of a degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category."
