The walrus is easily recognised by its sheer size and magnificent tusks. It is a keystone species in Arctic marine ecosystems. The walrus was once threatened by commercial hunting, but today the biggest danger it faces is climate change.

Walruses and people

Threats to walruses

Climate change
Walruses depend on sea ice as a platform for feeding and resting, and a warming Arctic is disrupting their normal patterns. In the past decade, earlier melting of sea ice in summer sea ice has forced abnormally large numbers of Pacific walruses ashore on the coasts of Russia and Alaska. These “haulouts” of up to 35,000 individuals can be deadly, particularly for walrus calves that are crushed in stampedes provoked by disturbances.
Industrial impacts
As sea ice melts, walrus populations will be exposed to more industrial activity, like shipping and oil and gas exploration. In addition to direct impacts like icebreaking ships and disturbance to walruses on shore, there’s an increased risk of oil spills. A WWF study found that oil spills on ice are virtually impossible to clean up.
Unsustainable hunting
Limited numbers of walrus are hunted in the United States, Canada, Greenland, and Russia. WWF supports up-to-date research into population trends to ensure the hunt remains sustainable.

Belugas are extremely sociable mammals that live, hunt and migrate together in pods, ranging from a few individuals to hundreds of whales.


The narwhal is famous for the long ivory tusk which spirals counter-clockwise several feet forward from its upper lip. The tusk is actually the whale's upper left canine tooth. Male narwhals commonly have a single tusk, but they sometimes have two tusks, or none at all. Around 15% of females have a tusk.
