description Sperm Whale Overview
A massive, block-shaped head gives the sperm whale an unmistakable profile. It is the largest toothed whale and the largest living toothed predator, with adult males reaching about 20 meters. The head contains the spermaceti organ, and the species has the largest brain of any living animal. Unlike baleen whales, sperm whales use teeth and suction to capture individual prey.
Deep dives take them beyond 1,000 meters in search of squid, including giant squid, as well as other deep-water prey. Their social lives differ by sex and age: females and young form lasting family units centered on maternal relationships, while mature males often travel alone and younger males may gather in bachelor groups. The species is classified as vulnerable. Its deep-ocean feeding and complex family behavior make it distinctive within comparisons of large whales.
