The Sperm Whale is the classic whale of 'Moby Dick' fame, and is the largest of the toothed whales. Female Pygmy Sperm Whales are generally only about two-thirds the length of the males and half the weight. Despite this dimorphism, the sexes are very similar in appearance with a shape unlike that of any other whale.
The distribution shown is generalised from the Departments Species of National Environmental Significance dataset. This is an indicative distribution map of the present distribution of the species based on best available knowledge. Some species information is withheld in line with sensitive species polices.
They also have the largest brain out of any animal known to exist. Female sperm whales on the other hand tend to be much smaller growing to lengths of 34 — 38 ft. The head of the whale contains an organ known as the spermaceti organ, hence its name, which was once believed to produce sperm, but has since been proven to serve another unknown use.
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.
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 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.
Physical Description The Sperm Whale is the largest of the toothed whales and is the best known member of the whale family. The most distinctive feature is the large blunt and squared off head and the small, underslung jaw. A single blowhole is located forward on the left side of the head and the blow is projected forward, rather than straight up as it is with other whales. Its body has a shriveled appearance, particularly behind the head.
