The Jaws of a Cetacean

The Jaws of a Cetacean

A sperm whale is the largest of the toothed whales and the largest toothed predator that is found around the world – but its teeth are only on the underside of its jaws. Some other interesting facts:

  • Females and young males live together in groups, while mature males (bulls) live solitary lives outside of the mating season.
  • Females give birth every four to twenty years, and care for the calves for more than a decade.
  • Its head represents up to one-third of its length.
  • Plunging to 2,250 meters, it is the third deepest diving mammal on the planet.
  • It has the largest brain on Earth, more than five times heavier than a human’s.
  • Sperm whales can live 70 years or more.
  • Sperm whaling was a major industry in the 19th century.
