Ocean Fact:

The flukes of a sperm whale as it dives into the Gulf of Mexico (courtesy NMFS)

Sperm whales (Physeter macrocephalus) use echolocation to find food. The whale emits a beam of high-frequency clicks. Structures in the whale’s head help to form & focus the sound beam. Returning sounds are received & transmitted to the inner ear allowing the whale to form a “picture” of its surroundings.
