Catfish
Catfish live in coastal waters and freshwater habitats in every part of the world except Antarctica, living life as bottom feeders. Catfish have broad, flat heads, and very prominent whiskers that protrude from their mouth.
It is these whiskers, or barbels, that are responsible for their feline name. The barbels are for more than just show, though, and are in fact used to smell and sense food and prey.
