Quick answer
Walruses feed on clams, molluscs, and occasional seals or seabirds, adjusting with season, age, and what is abundant in Arctic seas, pack ice, and coastal haul-outs. That label is a preferred pattern, not every item an individual might sample.

Walrus diet overview
Walruses (Odobenus rosmarus) are best summarised as Carnivore — clams, molluscs, and occasional seals or seabirds. Anatomy and habitat (Arctic seas, pack ice, and coastal haul-outs) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How walruses 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.
Walrus role in the food web
As predators or scavengers, walruses move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild walruses. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Tusks and feeding
Walrus tusks are elongated upper canines that can exceed one metre in large males. They are used to pull the body onto ice, establish dominance, and help the walrus 'feel' the seabed while foraging. A walrus may consume thousands of clams in a day, using powerful lips to suck meat from shells.

Walrus FAQs
What do walruses eat?
Walruses feed on clams, molluscs, and occasional seals or seabirds, adjusting with season, age, and what is abundant in Arctic seas, pack ice, and coastal haul-outs. That label is a preferred pattern, not every item an individual might sample.
What is the scientific name of the walrus?
Odobenus rosmarus — used in research and conservation listings for walruses.
Where do walruses live?
They are associated with Arctic seas, pack ice, and coastal haul-outs. Local presence depends on food, cover, and human land use.
What is the conservation status of walruses?
Listed in our guides as Vulnerable. Check the IUCN Red List and national assessments for the latest formal category.
Social haul-outs
Walruses rest in dense groups on sea ice or rocky beaches, vocalising with bell-like calls and whistles. Pacific walruses depend heavily on floating ice over shallow feeding grounds; when ice retreats beyond reach of feeding areas, animals haul out on land in enormous, sometimes dangerous crowds.
