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

- Climate change decided who ruled as top predator...on August 13, 2026 at 5:40 pm
An international team of researchers from Belgium, France, Switzerland, Spain and the U.S. has reconstructed the evolution of body mass in carnivorous mammals during the Paleogene—a crucial window in the diversification of mammals that followed the extinction of dinosaurs. This work, published in Biology Letters, challenges the long-standing hypothesis that competition decided the fate of ancient top predators.

Postdoctoral researcher Renato Borras-Chavez's area of study—pinnipeds in the Southern Ocean—often takes him far from the University of Rhode Island campus. Now, the researcher in Sarah Kienle's CEAL Lab is sharing more about declining populations of certain seals and will present on the topic at the SCAR Open Science Conference in Oslo, Norway, this August.
- What 'Neil the Seal' can teach us about seal...on July 17, 2026 at 12:40 pm
Neil the Seal became a social media sensation almost overnight. Neil is a 5-year-old male southern elephant seal who weighs roughly 1 metric ton (1.1 tons). He was born on the Tasman Peninsula in October 2020 and has made an annual trip to Tasmania since. This is because many seal species regularly return to the place they were born, as well as the sites where they breed and rest.
