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.

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 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.

Walruses and people

Walruses have long played an important role in the culture, economies and diets of Arctic peoples. Walrus meat, fresh or fermented, supplements locals’ diets in a region where store-bought food can be prohibitively expensive. Artists carve walrus ivory, and this practice provides cultural benefits and much-needed income.

What WWF is doing for walruses

Working with communities
WWF works with Arctic Peoples to protect habitat and reduce industrial threats to walrus.

Planning for a warmer Arctic future
WWF's work on climate change aims to cut global greenhouse gas emissions to prevent dangerous climate change, and aims to help species such as the walrus adapt to changes which are already occurring.

Did you know?

    • All male walruses, and some female walruses, have a large air sac in their throat which helps keep their head above water and also makes a bell-like sound during mating.
    • The tusks of a walrus can reach 1m in length.
    • The word walrus is thought to be derived from an Old Norse word meaning "horse-whale".
