Males ar… , Walruses prefer shallow shelf regions and forage primarily on the sea floor, often from sea ice platforms. This is similar to modern humans, whose testes are also of very modest size and produce a relatively small amount of sperm. It disturbs (bioturbates) the sea floor, releasing nutrients into the water column, encouraging mixing and movement of many organisms and increasing the patchiness of the benthos. Both in Chukotka and Alaska, the aurora borealis is believed to be a special world inhabited by those who died by violence, the changing rays representing deceased souls playing ball with a walrus head.

They are pink in warm weather when tiny blood vessels in the skin dilate and circulation increases.

Both the killer whale and the polar bear are also most likely to prey on walrus calves. The walrus relies on this ice while giving birth and aggregating in the reproductive period.

The weight of the heaviest polar bear is reported at 1,000 kg.  The bears also isolate walruses when they overwinter and are unable to escape a charging bear due to inaccessible diving holes in the ice. Females molt over a more prolonged period.
