Habitat
Atlantic walruses primarily inhabit the Arctic regions of the North Atlantic, including coastal areas around Greenland, Svalbard, and eastern Canada. They prefer pack ice, shallow waters, and beaches where they can haul out to rest. Their habitat is characterized by cold marine environments with access to benthic feeding areas.
Diet
Atlantic walruses mainly feed on benthic invertebrates such as clams, mussels, and snails, which they extract from the ocean floor using their tusks and suction. They occasionally eat fish, squid, or even marine mammals like seals. Feeding typically occurs in shallow waters during low tide or at night when prey is more accessible.
Behavior
Atlantic walruses are highly social, forming large herds on ice floes or beaches where they haul out to rest and socialize. They are mostly diurnal but can be active at any time, with males displaying territorial behavior during breeding by using tusks to fight for dominance. They communicate through vocalizations and migrate seasonally to follow retreating ice.
Conservation Status
The Atlantic walrus is classified as Vulnerable by the IUCN due to threats like climate change-induced ice loss and historical overhunting. Population trends indicate declines in some areas, with efforts focused on reducing hunting and protecting habitats.
