walrus

Freya became a global celebrity last year after she was seen frolicking and basking in a Oslo fjord before she was euthanized by the authorities. A bronze sculpture now honors her in Norway's capital.

Conservationists are trying to track walrus populations amid climate change but they can't do it alone.

The Trump administration refused last month to put the Pacific walrus on the endangered species list, spelling a "death sentence" for the species that lives in the seas between Alaska and Russia.

Groups of walruses are vulnerable to disturbances, but it's hard to avoid them if you don't know where they are. A new tool from U.S. and Russian researchers draws on history to protect the animals.
