Sperm Whale

The sperm whale is a toothed whale with a massive, square-shaped head and a relatively narrow lower jaw. It dives deeply to hunt squid and other prey, using echolocation in dark water. Its blowhole lies near the front left side of the head. Females and young commonly live in social groups, while mature males range more independently. Tail flukes may rise above the surface before a deep dive. Sound is central both to locating food and to maintaining contact with other whales.
