The walrus palate is uniquely vaulted, enabling effective suction; researchers measured pressures in the oral cavity as low as -87.9 kPa in air, and -118.8 kPa underwater. [77] Walruses at the Tierpark Hagenbeck were easily able to suck the five-pound metal plug out of the bottom of their pool, at a water depth of 1.1 metres. [78]
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 ...
Articles relating to Walruses (Odobenus rosmarus), with their uses and depictions in human culture. The species represents a large pinniped marine mammal with discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere. It is the only extant species in the family Odobenidae and genus Odobenus.
The citizen science scheme by WWF and British Antarctic Survey aims to help conserve walruses in the face of climate change. Walrus detectives: public asked to count Arctic mammals in satellite images
Scientists say warmer climate cycles mean sea ice, where walruses traditionally haulout, is shrinking, and that they are threatened from oil and gas exploration and more Arctic shipping.
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.
Meanwhile, the young walrus feasts on clams for three days with the rest of its herd on a clam bed they might revisit in another five years. The two animals then take similar paths. They have to travel because shorter winters mean ice that freezes later and melts sooner, making it harder to survive and eat as the water of Arctic Ocean expands ...
Tourists who want to view Alaska's Pacfic walrus may want to do it sooner rather than later. The Interior Department has decided that global warming is threatening the Pacific walrus, but will not ...
