Catfish

A catfish is any fish of the order Siluriformes. The name comes from the fact that many kinds of catfish have barbels resembling a cat's whiskers.

Economic importance[edit]

Some of the larger kinds of catfish are raised as food, while some of the smaller kinds are kept in aquariums as bottom feeders and algae eaters.
