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]
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
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 ...
Polar regions are dry areas; there is very little precipitation due to the cold air. There are some times when the humidity may be high but the water vapor present in the air may be low. Wind is also strong in the polar region. Wind carries snow creating blizzard like conditions.
Fourteen walruses are now in human care in the United States.
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 ...
