Unlike most mega bats, they use a simple form of echolocation to navigate. There may be more myths about bats than any other animal. Some people think bats are blind bloodsuckers that fly into your hair and carry rabies. In fact, this flying mammal is extremely useful to humans. Like other mammals, bats are warm-blooded, have hair, and give birth to live young.
Some bats migrate to warmer climates during the winter, others hibernate.
Bats Great and Small Bats are divided into two major groups. They have big eyes and excellent eyesight. The largest bat, at two pounds, is the giant flying fox with a wingspan of six feet. Included in this group is the smallest bat, the bumblebee bat, weighing the same as a penny and less than two inches long. Bat wings contain the same bones as a four-fingered human hand.
