Bats are the only mammals that can fly, but vampire bats have an even more interesting distinction- they are the only mammals that feed entirely on blood. In one year, a 100-bat colony can drink the blood of 25 cows. Sleeping cattle + horses are their usual victims, but they have been known to feed on people as well. They don’t remove enough blood to harm their host, but their bites can cause nasty infections + disease. The bats have few teeth because of their liquid diet, but those they have are razor sharp. The common vampire bat is found in the tropics of Mexico, Central America + South America. Now you can have your own specimen encased in resin! Measures 3 inches square.
