Catfish are a group of fish that appearance wise usually have cat-like whiskers. They are actually barbers (although some catfish species do not have these). Some species of catfish can grow up to 3 meters while others can only grow up to 3 centimeters. Like many other fish, catfish use sounds created by their swimbladder to communicate with other catfish.
