Today there are several hundred kinds of bats. They live everywhere in the world except near the polar regions. Bats are the only mammals that can fly. They range in size from 15 cm wings spread to two meters wings spread!
Most bats eat insects. Many bats of the tropics eat fruit or the pollen from flowers. Other bats eat fish or smaller bats. Some of them eat blood.
The blood-eating bats are called “vampire bats.” It is on account of this variety of hats that people are so frightened of all bats. There was a time, when in Eastern Europe, there were many legends about vampires. A vampire was the soul of a dead person, which assumed the form of some animal at night and roved the countryside looking for victims from which to suck the blood. During the early 18th century, explores who travelled to South and Central America found bats that fed on blood. They returned with exaggerated stories and soon, all the old vampire legend stories were associated with bats. Since that time, vampires have been thought of mostly as bats.
Vampire bats are found in Central and South America. They have a wing spread of about 30 cms and a body length of about 10 cm. They have needle-sharp front teeth; with which it makes small cuts in the skin of its victim. It was thought that a vampire bat sucked blood, but it actually laps it up with its tongue. Factually, a Vampire bat can be feeding on its victim, while the person remains asleep.
It is thought, its saliva contains some substance that deadens the pain of the wound, as well as something that prevents the blood form clotting. Vampire bats do not prefer to feed on human beings. They are just as happy to feed on horses, cows, goats and chickens. There are places where vampire bats have transmitted a disease that is sometimes fatal to the victim.
