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 — Merriam-Webster See also OneLook
Encyclopedia
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 have 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 social animals, and they are considered to be a “keystone species” in the Arctic marine regions. — Wikipedia

Science
Mammalogy is the study of mammals – a class of vertebrates with characteristics such as homeothermic metabolism, fur, four-chambered hearts, and complex nervous systems. Mammalogy has also been known as “mastology,” “theriology,” and “therology.” The major branches of mammalogy include natural history, taxonomy and systematics, anatomy and physiology, ethology, ecology, and management. — Wikipedia

- Svalbard polar bears show improved fat reserves...on January 29, 2026 at 4:00 pm
The body conditions of polar bear (Ursus maritimus) populations around the Norwegian island of Svalbard have improved despite sea ice losses, according to new findings. The findings differ from previously published observations of polar bear population declines coinciding with sea ice loss across the Arctic.
- Q&A: Climate shifts drove carnivores' evolution...on December 17, 2025 at 8:59 pm
The ancestors of our furry cats and dogs once looked similar to today's modern mongoose, a mammal with a long body and small, round ears. In fact, all members of the order Carnivora, which includes a variety of mammalian species, such as bears, wolves and even seals, evolved from these 'mongoose-like' creatures.
- Arctic sees unprecedented heat as climate impacts...on December 16, 2025 at 7:01 pm
The Arctic has experienced its hottest year since records began, a US science agency announced Tuesday, as climate change triggers cascading impacts from melting glaciers and sea ice to greening landscapes and disruptions to global weather.
