The sperm whale or cachalot [a] Physeter macrocephalus is the largest of the toothed whales and the largest toothed predator. It is the only living member of the genus Physeter and one of three extant species in the sperm whale family , along 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 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. Their most prominent feature is the bulbous squared head and huge conical teeth in the lower jaw.
The inspiration for the white whale of Moby Dick, sperm whales have the largest heads, biggest brains, and make the loudest sound of any animal on Earth. Region: Arctic, Antarctica. Helena, Tristan da Cunha, Iceland. Short, wide flippers, broad, triangular fluke, and a single blowhole. Sperm whales usually eat a little over kg almost 2, pounds of food per day.
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 spermaceti is an oil sac that helps the whales focus sound.
