Quick answer
Sperm Whales feed on squid, deep-sea fish, and occasional sharks, adjusting with season, age, and what is abundant in Deep offshore waters worldwide; males range into polar seas. That label is a preferred pattern, not every item an individual might sample.

Sperm Whale diet overview
Sperm Whales (Physeter macrocephalus) are best summarised as Carnivore — squid, deep-sea fish, and occasional sharks. Anatomy and habitat (Deep offshore waters worldwide; males range into polar seas) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How sperm whales find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Sperm Whale role in the food web
As predators or scavengers, sperm whales move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild sperm whales. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Extreme deep diving
Sperm whales hunt in darkness more than a kilometre down, holding breath for over an hour. Spermaceti organs in the huge head may aid echolocation or buoyancy control. Scars from giant squid tentacles are common on bulls.
Pod society and clicking
Females and young live in stable matrilineal pods, while mature males roam alone or in bachelor groups at higher latitudes. Coda clicks — patterned sequences — may function as clan identifiers across populations.
