Bat Facts: What’s with the hanging?

Q: WHY DO BATS HANG UPSIDE DOWN?

A: Unlike the bodies of other animals, a bat’s body is best adapted for hanging upside down. Its hind limbs have rotated 180 degrees so that its knees face backwards. This rotation aids in the bat’s ability to navigate in flight and to hang by its feet. Bats actually have specialized tendons that hold their toes in place so that they are able to cling to their roosts without expending any energy. In fact, bats must flex their muscles in order to let go of the roosting surface. These adaptations are quite helpful for a flying mammal since bats only need to let go of the roost in order to drop into flight. Hanging upside down also provides bats with roosting space away from predators in safe places on the ceilings of caves, in trees, and buildings that few other animals can use because they have not evolved to hang upside down by their feet.

    Great answer. That makes sense. I have also heard that with bats, if they are flyinh around at night, if you somehow clap it can mess up their radar. I am not sure, exactly, what it is or was, however.
