Order : Chiroptera
Bats are the cause of many myths and have always appealed to our imagination. Be it in a good way, like Batman, or in the form of Dracula. Bats are mammals that can fly because they adapted their forelimbs into wings. Their wings are, unlike birds, skin supported by four fingers. Bats are the only mammals that can fly. Most feed on insects, some have the ability to feed on fruits. Vampire bats really do exist, but only three species in Central and South America are known. Vampire bats feed on large birds, cows, horses and pigs.
All of the members of chiroptera (bats) are active during the night or during the twilight. Instead of relying on their sight, bats have excellent senses of smell and hearing. By emitting high-pitched sounds and listening to the echoes, the bats sense prey and other nearby objects. This is called echolocation. Echolocation is also common among dolphins and whales.
