Many aquatic animals are filter feeders, which strain small organisms or food particles from the surrounding medium. The humpback whale, shown above, is one example. Attached to the whale’s upper jaw are comblike plates called baleen, which remove small invertebrates and fish from enormous volumes of water and sometimes mud. Filter feeding in water is a type of suspension feeding, which also includes removing suspended food particles from the surrounding medium by capture or trapping mechanisms.
