In zoos, colonies of this species are like yeast — a few sent to another zoo soon reproduce to the carrying capacity of their exhibit, and more colonies can be established from there. From a few importations more than 30 years ago, there are now more than 6,000 of these fruit-eating bats distributed among more than 30 North American collections. This is a widespread species, found from Mexico to Paraguay. In the Mayan epic, the Popol Vuh, a bat, Zotz, stole the head of the Hero God Hunahpu for the Gods of the Underworld to use in a ballgame.
It might seem surprising that Vampire bats have the fewest number of teeth of any bat — only 20, most of them tiny. However the incisors and canines, that dominate their jaws, are superbly suited to slice through skin, giving their owner access to the blood that is its sole food. Found from Northern Mexico to Chile, they prey on a wide variety of sleeping mammals and birds, including occasional humans (who are often attacked through their toes). They do well in captivity, and most zoo specimens are captive-bred. Their DWA diet is cow’s blood.
