How do bats not fall when sleeping?

The bumps on the tendons are angled so that once the ribbings slide in, they lock in place. This takes almost no effort from the bat, so it's called "passive digital lock."

Cave bats feed at night, catching insects such as moths, flying beetles, and mosquitoes. They use ultrasonic sound, called echolocation, to locate their food. This echolocation involves emitting a high frequency sound which bounces off obstacles.

How do bats grab things?

First, a bat flies into position, then opens its claws and grasps until it discovers a surface to grip. Bats simply relax and their talons grab hold of the surface. Its weight helps keep their claws closed. The upper body pulls down on the tendons connected to the talons and causes them to clench.

How do bats climb?
