What Big Ears

Most frogs have excellent hearing, but cannot hear the highest or lowest sounds that humans hear.

A frog’s eardrum, or tympanum, is on the outside of its body just behind the eye.

The size of the eardrums and the distance between them determine which sounds a frog hears best.

To protect its sensitive ears, a frog may produce special vibrations in its body to partly block the sound of its own loud call.
