★ 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.

★ These notorious bats sleep during the day in total darkness, suspended upside down from the roofs of caves.

★ They typically gather in colonies of about 100 animals, but sometimes live in groups of 1,000 or more.

★ In one year, a 100-bat colony can drink the blood of 25 cows.

★ Rather than sucking blood, vampire bats make a small cut with their teeth and then lap up the flowing blood with their tongues.Its saliva prevents the blood from clotting..

★ Vampire bats need about 2 tablespoonfuls of blood each day. The creature is able to extract its dinner in approximately 20 minutes.

★ Each bat has a heat sensor on its nose that points it toward a spot where warm blood is flowing just beneath its victim's skin.A warmer spot is where the blood is close to the surface.

★ These bats are so light and agile that they are sometimes able to drink blood from an animal for more than 30 minutes without waking it up. The blood sucking does not hurt the animal.

★ The bats have few teeth because of their liquid diet, but those they have are razor sharp.

★ Vampire bats only need blood to survive. If they could not find blood within 2-3 days, they will die. A normal daily blood diet for a bat is about ½ its body weight.
