Sperm Whale

Physeter macrocephalus

Also Called: Cachalot

The head of the sperm whale is its most distinctive feature. It is very blunt and square with a small lower jaw and can take up 1/3 of its total body length. The sperm whale has a single blowhole and its blows project forward and to the left (instead of straight up as in other whales.) The sperm whale is primarily a dark, brownish gray with white patches around its mouth and with a lighter gray ventralWhat does ventral mean? surface. The skin of the sperm whale is very wrinkled particularly behind its head. The sperm whale does not have a pronounced dorsalWhat does dorsal mean? fin. It is more of a large bump on its back. However, the flukeWhat does fluke mean? of a sperm whale is very large (16 ft). The sperm whale is the deepest of the whale divers and can dive to depths of 3300 feet and stay down for over an hour. At these depths, there is no visible solar light so sperm whales use a highly developed sonarWhat does sonar mean? system. It is possible that they use bursts of sound to stun preyWhat does prey mean?. In the forward part of a sperm whales head is the spermaceti organ.
