Do walruses live in Alaska?
Yes, walruses live in Alaska. Pacific walruses inhabit the shallow waters of the Bering and Chukchi seas, hauling out on sea ice and coastal beaches between Bristol Bay and the Arctic coast. They are a key cultural, subsistence, and ecological species for Alaska Native communities. This overview covers where they live, how they behave, and how their populations are managed.
Walrus distribution in Alaska
Walruses range through seasonally ice-covered waters of the North Pacific, with the Alaskan population spanning from the Bering Strait south to the Aleutian Islands and east into the Beaufort and Chukchi seas. Major haulouts occur on St. Lawrence Island, the Pribilofs, the Diomedes, and around ice edges in spring and summer. Their distribution tracks the edge of sea ice and productive foraging grounds where they feed largely on benthic clams and other invertebrates.
Seasonal patterns
- Spring: Concentrated over the continental shelf ice, moving northward as ice retreats.
- Summer: Haulouts on islands, barrier beaches, and ice fragments; foraging in shallow waters.
- Fall and winter: Migration toward southern Bering Sea and into the Bering Strait region as ice forms.
Habitat and foraging ecology
Walruses rely on sea ice as a platform for resting, molting, and raising young, while shallow-water foraging depends on soft sediments rich in bivalves. Their tusks help them haul out on ice and defend against predators, including occasional polar bears and orcas. They can dive beyond 80 m and remain submerged for more than half an hour, though many foraging bouts occur in waters under 30 m.
Conservation and management
Alaskan walrus populations are managed by the U.S. Fish and Wildlife Service in consultation with Alaska Native organizations. Listed as ‘vulnerable’ by the IUCN, they face risks from climate-driven sea ice loss, which affects access to feeding and hauling habitat. Subsistence harvest is allowed under co-management agreements, emphasizing careful monitoring and community-based stewardship.

Behavior and life history
Walruses are highly social, forming large aggregations during molt and on haulouts. They use vocalizations, tusk clacking, and body postures to communicate. Calves are born on sea ice after a 15–16 month gestation and stay with their mothers for multiple years, learning diving and foraging skills. Predation pressure is generally low in most areas, but environmental change can increase stress and exposure.
Threats and climate impacts
Sea ice loss is the primary long-term concern, reducing access to traditional haulouts and foraging areas. Additional stressors include ocean acidification affecting prey, potential oil spills, and disturbance from vessel traffic and industry activities. Continued monitoring, habitat protection, and integration of Indigenous knowledge are central to conservation planning.
How to observe walruses in Alaska
Responsible viewing is possible from coastal communities, vessel-based wildlife tours, and select viewing platforms. Observe from a distance, avoid approaching haulouts, follow local guidance, and prioritize operators with wildlife viewing protocols. Community-based ecotourism in regions such as the Pribilofs and Nome can provide culturally informed, low-impact opportunities to see walruses in the wild.
