Habitat
Laptev walruses primarily inhabit the Arctic waters of the Laptev Sea, favoring areas with sea ice floes for resting and breeding. They are often found in shallow coastal regions and continental shelves where they can access the seafloor for food. Their range is limited to the Russian Arctic, preferring cold environments with pack ice.
Diet
Laptev walruses mainly feed on benthic invertebrates such as clams, mussels, and snails, which they extract from the seafloor using their tusks and suction. They also consume worms, crustaceans, and occasionally fish, foraging in shallow waters during daylight hours. Feeding dives typically last 5-10 minutes and occur multiple times a day.
Behavior
Laptev walruses are highly social, forming large herds on ice floes or beaches, with males establishing dominance through vocalizations and physical displays. They are diurnal, spending much of the day resting on ice and foraging underwater at night, and exhibit migratory behavior following seasonal ice movements. Territorial disputes among males are common during breeding season, but they generally tolerate close proximity in groups.
Conservation Status
The Laptev walrus is not separately assessed by the IUCN, but as a subspecies of the walrus, it falls under the Least Concern category for the Pacific walrus, with potential threats from climate change and habitat loss due to melting sea ice. Population trends are poorly understood, but hunting and environmental changes pose risks.
