Quick answer
Sperm Whales feed on carnivore — squid, deep-sea fish, and occasional sharks, adjusting seasonally based on local habitat and prey or plant availability.
Diet overview
Sperm Whales are mammals that rely on carnivore — squid, deep-sea fish, and occasional sharks. The sperm whale is the largest toothed predator on Earth, with males reaching 16–20 m (52–66 ft) and over 50 tonnes. Famous for deep dives exceeding 2,000 m hunting giant squid, it has the largest brain of any animal and lives in social female-led pods across the world's oceans.
Feeding behaviour
Foraging strategy varies by season. Sperm Whales may hunt, graze, filter-feed, or scavenge depending on ecology.
Role in the food web
As mammals, they interact with predators, prey, and competitors across their range.
Human-related feeding risks
Never feed wild sperm whales — it habituates animals to people and can spread disease.
