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. Females give birth every four to 20 years, and care for the calves for more than a decade. A mature sperm whale has few natural predators, although calves and weakened adults are sometimes killed by pods of killer whales orcas. Sperm whales can live for more than 60 years.

Deep Mystery: How Huge Whales Hunt Jumbo Squid
Sperm Whale is one of the most amazing creatures we have on our planet. This particular animal holds several records apart from being the largest creature on Earth — the crown that goes to Blue Whale that might come as a serious shock to anyone. So, let us learn some really interesting Sperm Whale facts that we think you might like and even need for your school project. Before we start with the list of Sperm Whale facts, let us quickly take a look at the scientific classification of animal.
In the cold, dark abyss of the Pacific lurk thousands of aptly named jumbo squid Dosidicus gigas , aggressive carnivores up to six feet long and pounds nicknamed "red devils" by fishermen. Still, even these creatures can become prey to leviathans. The largest predators in the world, sperm whales, have a voracious appetite for squid, devouring perhaps billion pounds a year or more, roughly equivalent to the entire annual harvest of all the commercial fisheries on Earth. Now, by electronically tagging both to peer at their habits up to thousands of feet underwater, scientists are discovering a deep sea version of "out of the frying pan and into the fire," with squid that flee the relative heat of surface waters potentially finding themselves in the maws of whales. Marine scientist William Gilly at Stanford University and his colleagues were tagging jumbo squid in the Gulf of California, also called the Sea of Cortez.

Sperm whales have several specialized physical characteristics that aid in this predatory behavior. They have large conical teeth for ensnaring their preferred prey. Like most active predators, they have large brains and in fact, the sperm whale has the largest brain of any animal on the planet.
