There are two subspecies of walrus — the Atlantic and Pacific. For both, their world is changing fast.
Walruses may be massive, but they are incredibly sensitive to sounds and stress. Shrinking sea ice is opening the Arctic to economic opportunities, including oil and gas exploration and increased shipping through sensitive marine habitats. That noise and activity is hard on the walruses. A disturbance can result in a stampede, which may be lethal to these animals.
To see the heartbreaking effect of panic among Pacific walruses, watch this video from Our Planet, a Netflix original documentary series and collaboration involving Netflix, Silverback Films and WWF.
