Diet: Sperm whales are carnivores (meat-eaters) that mostly hunt giant squid that live on the ocean bottom at great depths. They also eat fish, octopus, and skate.

Echolocation: Like other toothed whales, the Sperm Whale uses echolocation, a way of sensing in which they emit high-pitched clicks and sense them as they bounce back off objects (like prey). This is crucial in hunting in the dark ocean depths.
