The Common Vampire Bat (Desmodus rotundus) is a species from the Desmodus genus. It is a small, leaf-nosed bat native to the Americas.


Physical description[]

The common vampire bat is short-haired, with silver-gray fur on its undersides, sharply demarcated from the darker fur on its back. It has small, somewhat rounded ears, 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 long with a wingspan of 18 cm. It commonly weighs about 57 grams, but its weight can double 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. Common vampire bats exhibit sexual dimorphism in which females are bigger than males.

Range and habitat[]


Needs Information...


The common vampire bat feeds primarily on mammalian blood, particularly that of livestock such as cattle and horses. Vampire bats feed on wild prey like the tapir, but seem to prefer domesticated animals, and favor horses over cattle when given the choice. Female animals, particularly those in estrus, are more often targeted than males. This could be because of the hormones.


The lifespan is about 5 to 10 years
