The sperm whale is the largest toothed predator on Earth and the deepest-diving mammal, capable of descending over 3,000 meters in search of giant squid. The massive square head, which comprises up to one-third of the animal’s body length, houses the spermaceti organ — a vast reservoir of waxy oil believed to function in buoyancy regulation and the focusing of powerful echolocation clicks. These clicks are the loudest sounds produced by any animal, reaching 230 decibels.
