Their wings are really webbed hands. Thin, elastic skin stretches right across their very long fingers to their hind legs. There are over 950 different kinds of bats. They vary greatly in size, color and habits. Most bats measure about 8-12 inches from wing tip to wing tip and weigh less than an ounce.
Bats rely on sounds to navigate, communicate and capture insects.
They can produce as many as 250 beeps per second. When these sounds hit an object, they bounce back to the bats as echos. From these echoes bats can determine the size, shape, texture, and distance of objects. This process is called echolocation. Most species of bats eat night-flying insects.
