Formerly known as Physeter catodonthe Sperm whale is the largest of the toothed whales Odontoceti. Males reach 50 to 60 feet 15 to 18 m and weigh 48 tons 43 m toneswhile females grow to feet 4. This species is very distinctive looking, with a massive bluntly square head which can be one third the length of its body.
It is the only living member of the genus Physeter and one of three extant species in the sperm whale familyalong with the pygmy sperm whale and dwarf sperm whale of the genus Kogia. The sperm whale is a pelagic mammal with a worldwide range, and will migrate seasonally for feeding and breeding. The females cooperate to protect and nurse their young.

The sperm whale is dark blue-gray or brownish, with white patches on the belly. It is thickset and has small paddlelike flippers and a series of rounded humps on its back.
Sperm whales are the largest of the toothed whales and have one of the widest global distributions of any marine mammal species. They are found in all deep oceans, from the equator to the edge of the pack ice in the Arctic and Antarctic. They are named after the waxy substance, spermaceti, found in their heads.
The sperm whale is the largest toothed whale. Males reach 60 feet 17 m in length and the smaller females are 37 feet 12 m. They are dark gray in color, have a hump rather than a dorsal fin, and usually display their tail flukes when they dive.
They possess the largest brain in the animal kingdom and spend much of their lives in the light-starved depths of the oceans hunting prey. The mighty sperm whales look nothing like any other whale. For a start, they each have an enormous square-shaped head which accounts for around a third of their body length.
Sperm whales roam the deep waters of all the oceans, though they seldom approach polar ice fields and are most common in temperate and tropical latitudes. They have also be seen occasionally near coastlines in the Gulf of Mexico, where they were once quite common. Sperm whales swim through deep waters to depths of 2 miles, apparently limited in depth only by the time it takes to swim down and back to the surface.
The sperm whale received its name from an organ inside its head—the spermaceti organ—that old-time whalers used to believe produced sperm. Instead, the spermaceti organ contains high quality oil. Sperm whales are very difficult to study because they spend most of their time in open water, away from coastlines.
The Sperm Whale is the largest of all toothed whales, and many people immediately think of the story of Moby Dick when they see one. It is well known for the grayish color that it features. The unique body design also offers a very large head with rows of sharp teeth.
