The Sperm whale is the largest of the toothed whales and can grow up to sixty six feet. It can be found in oceans world wide. Its head alone equals about one third of its entire body. These water living mammals can dive to at least 3,300 feet, maybe more, in search of one of its prey, the squid, as well as other types of fish and lobster. At this depth, they use sonar, the process of sending out sounds that reflect off an object and return to the animal's ears, to locate prey.
