Quick answer
Narwhals feed on fish, squid and shrimp, adjusting with season, age, and what is abundant in Arctic oceans and ice-edge waters. That label is a preferred pattern, not every item an individual might sample.

Narwhal diet overview
Narwhals (Monodon monoceros) are best summarised as Carnivore (fish, squid, shrimp). Anatomy and habitat (Arctic oceans and ice-edge waters) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How narwhals 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.
Narwhal role in the food web
As predators or scavengers, narwhals move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild narwhals. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
The tusk that inspired unicorns
The narwhal's spiraled tusk is its most famous feature — a single tooth that grows straight through the upper lip and can reach 3 m (10 ft) long. Found mainly in males, it is packed with millions of nerve endings, making it a sensitive organ as well as a possible weapon. In medieval Europe, narwhal tusks were sold as unicorn horns for enormous sums.
Life in the Arctic ice
Narwhals are one of the few whales that live in the high Arctic all year, moving with the advancing and retreating sea ice. In winter they dive beneath dense pack ice to depths of more than 1,500 m (4,900 ft) in search of fish, surfacing to breathe through narrow cracks and breathing holes in the ice.
