Despite their fearsome name, vampire bats are kind of adorable.
These fuzzy flyers include three species of bats that live in Mexico, Central and South America. Two are the hairy-legged vampire bat and the white-winged vampire bat. But the most abundant and well-known species is the common vampire bat (Desmodus rotundus).
Just a few inches long, common vampire bats spend their days hanging upside-down from creepy locations, such as the roofs of caves, hollow trees and empty buildings. They navigate through the darkest of nights with echolocation.
These critters often feed from sleeping cows, horses and other farm animals — but usually not humans. (The other two species of blood-drinking bats feed on birds and other forest animals.) When a vampire bat lands on its prey, it makes a small cut with its teeth and laps up the blood that spills out. This feeding is so stealthy that a bat can drink blood for half an hour without waking its prey. The bats don’t take enough blood to harm their hosts — though their bites can spread diseases such as rabies.
Common vampire bats live in groups of hundreds to thousands. Bats that live together are known to groom each other and even team up for hunting. When one bat can’t find food, another may even spit up some blood to feed its hungry neighbor.
So while vampire bats may literally be bloodthirsty, they can be surprisingly gentle with both their prey and each other.
