walrus : a large gregarious marine mammal (Odobenus rosmarus of the family Odobenidae) of arctic waters related to the seals that has limbs modified into webbed flippers, long ivory tusks, a tough wrinkled hide, stiff whiskers, and a thick layer of blubber — Webster
Walrus is a large flippered marine mammal with a discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere. The walrus is the only living species in the family Odobenidae and genus Odobenus. This species is subdivided into three subspecies: the Atlantic walrus (O. r. rosmarus) which lives in the Atlantic Ocean, the Pacific walrus (O. r. divergens) which lives in the Pacific Ocean, and O. r. laptevi, which lives in the Laptev Sea of the Arctic Ocean.
Adult walrus are easily recognized by their prominent tusks, whiskers, and bulk. Adult males in the Pacific can weigh more than 2,000 kg (4,400 lb) and, among pinnipeds, are exceeded in size only by the two species of elephant seals. Walruses live mostly in shallow waters above the continental shelves, spending significant amounts of their lives on the sea ice looking for benthic bivalve mollusks to eat. Walruses are relatively long-lived, social animals, and they are considered to be a “keystone species” in the Arctic marine regions. — Wikipedia

- Using eyes in the sky to locate seals in a...on September 14, 2022 at 6:46 pm
This summer, researchers managed to collect stunning drone images of both ringed seals and walruses. In one fjord, the St. Jonsfjorden, twelve ringed seals were found spread out throughout the fjord, resting on the fast ice. However, approaching and identifying these individuals is very challenging. Since ringed seals are hunted by polar bears, any mammal—either walking on four or two legs—will be avoided at all costs.
- Albatrosses from space: Wildlife detectives neededon September 5, 2022 at 2:59 pm
British Antarctic Survey (BAS) and RSPB are recruiting albatross detectives to help to search for wandering albatrosses in satellite images taken from space in an effort to learn more about how these sentinels of the sea are being impacted by climate change, intensive fishing, and invasive species.
- Why 'mercy' killing wild animals is so...on August 25, 2022 at 3:33 pm
Two wild animals that strayed from their ordinary habitats and into close proximity to humans were recently killed in high-profile cases. The life of Freya the walrus was ended by officials in Oslo on August 14 2022, reportedly because the animal posed a threat to humans. Four days earlier, the life of a beluga whale that had strayed into France's Seine River was ended during a failed rescue attempt.

A walrus nicknamed Freya that attracted crowds while basking in the Oslo fjord was euthanised on Sunday, with Norway officials saying it was the only option but experts slamming an "infinitely sad" decision.

The Bering Sea is the most productive ground fishery in the world, particularly for salmon, halibut and shellfish. About half of U.S. fish and shellfish come from that area and the fishing industry is the main driver of jobs in and around the Aleutian Islands. The freezing and melting of sea ice in the area heavily impacts the primary productivity, which is the bottom of the marine food chain.
