Description:

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 known 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 groups of females. It is one of the most social of bat species with a number of cooperative behaviors such as 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."

The common vampire bat is short-haired, with silver-gray fur on its undersides, demarcated from the darker fur on its back. It has a deeply grooved lower lip, and a flat, leaf-shaped nose. A well-developed, clawed thumb on each wing is used to climb onto prey and to assist the animal in take-off. The bat averages about 9 cm (3.5 in) long with a wingspan of 18 cm (7 in). It commonly weighs about 25-40 grams (2 oz), but its weight can drastically increase after a single feeding. The braincase is relatively large, but the snout is reduced to accommodate large incisors and canines.  It has the fewest teeth among bats. The upper incisors lack enamel, which keeps them razor-sharp.
