While birds rule the daytime skies, the bat, a flying mammal, is master of the air at night. Its leathery wings are made of flexible skin flaps that stretch between the incredibly long fingers of the bat's hands, making them very strong and efficient for flying. During the day, bats usually roost in large groups in caves, attics, or hollow trees, hanging upside-down with their clawed hind feet.

Most bats hunt for food such as moths, but some have different ways of feeding. Vampire bats from South and Central America feed on the blood of people, cows, and horses. Fruit bats, sometimes called flying foxes, feed on fruit of tropical trees. Hunting bats catch mice on the ground or fish that swim near the surface of a lake.

Bats find their food in complete darkness using a system called echolocation. The bat sends out very high-pitched noises (ultrasonic sounds) that "echo" or bounce off its prey. Using the echoes to locate its prey, the bat then chases, captures, and eats it.

More About Bats:

Backward pointing teeth


Backward pointing teeth are spikes used for holding onto prey.



The bat's breastbone acts as a main support for vast wings.



These foward-facing claws are mostly used for gripping branches.



Small and insignificant visual receptors compared to the bat's sonar system.



Air sacs used for ventilation.

Nose Flap


Used for broadcasting ultrasonic sounds only your dog can hear.

Sonar Receptors


Core navigational device for hunting down prey. First the bat sends out some ultrasonic rays, which bounce back and are recieved by this system.



Food processors.

Strut Supports


Filled with tubular veins containg blood and air.
