Walruses live to about 20–30 years old in the wild. [33] The males reach sexual maturity as early as seven years, but do not typically mate until fully developed at around 15 years of age. [5] They rut from January through April, decreasing their food intake dramatically. The females begin ovulating as soon as four to six years old. [5]
Japanese macaques can survive in cold temperatures of below −15°C (5°F), and are among very few primates that can do so.. Chionophiles are any organisms (animals, plants, fungi, etc.) that can thrive in cold winter conditions (the word is derived from the Greek word chion meaning "snow", and -phile meaning "lover").
Walrus calves learn a variety of special skills from their mother, and without that kind of training, will survive this orphaned infancy, but will depend on human care for the rest of her life.
Accounting for these environmental factors, walruses more frequently haul-out from late morning to early evening and avoid hauling-out during weather periods of intense cold or high winds. [8] [11] Haul-out frequency is at a maximum for walruses during the summer using terrestrial haul-out sites as sea ice sites are then further from foraging ...
Thousands of walruses gathered together here in the Arctic Circle - an area where their habitat is under threat from shrinking ice. A meet-up like this is called a 'haulout' - where vast numbers ...

Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not ...
