More than 2,000 kinds of bats exist in the world today. Some bats eat insects, some eat fruits or pollen and others eat fish or smaller bats. Some bats also feed upon blood. These blood-eating bats are called vampire bats. Vampire bats are found in South and Central America. They hunt in the darkest of hours. The vampire bat makes a cut in its victim’s skin with its front sharp teeth. Then, it licks it up with its tongue. Earlier, it was believed that a vampire bat sucks up blood.
