In 600 BCE, Greek legendary fabulist, Aesop, told a fable about a bat that borrowed money to start a business. The business failed, and the bat had to hide during the day to avoid those it owed money to. According to Aesop, this is why bats come out only at night.

Contrary to popular belief, vampire bats do not really “suck” blood. Instead, they typically “lap” up two teaspoons a night with their tongues. The blood moves through the bat’s mouth in two channels under its tongue. Its body uses only red blood cells, and within two minutes of starting to eat, the bat’s body rids itself of blood plasma in the form of urine.

Vampire bats have to drink as much as their own weight in blood every day. To give you an idea of how much that is, a human vampire like Dracula would have to drink the blood of a whole table full of guests every night just to stay alive.
