Fish don't have ears that we can see, but they do have ear parts inside
their heads. They pick up sounds in the water through their bodies and in
the ear, according to the National Wildlife Federation.

A fish also senses movement in the water with the lateral lines that runs
down each side of its body. Sharks, which are fish, have a keen ability to
sense electricity. Oddly the genes that contribute to this ability are
responsible for the head and facial features in humans, linking sharks and
humans to a common ancestor way back in time.

Human ears, interestingly, evolved from fish gills.
