Common Vampire Bat: Desmodus rotundus

Desmodus rotundus is known as the Common Vampire Bat.  It is one of three species of vampire bats.  These bats prey upon the blood of cattle, horses, pigs, humans, large birds and other large animals.  Contrary to popular belief, vampire bats do not suck the blood from their prey.  Instead they make an incision in their victims and then lap up the blood from the wound.
