Walrus

Walruses are known for their massive tusks — which on average are 50 centimeters (19 inches) long, but did you know they are just enlarged canine teeth?

 

Found in the Arctic and sub-Arctic regions around the world, the walrus is one of the largest members of the seal and sea lion group, reaching weights up to 1,557 kilograms (3,432 pounds). They are social creatures, spending most of their time both on land and in water in groups that can be either a few individuals or thousands! Typically, they spend most of their time with other walruses of the same sex. However, during the breeding season, they all gather in huge groups, called haul-outs, and get very close — sometimes even piling onto one another!  

Their tusks not only help them to get out of the water — with the ability to break through 20 centimeters (7.9 inches) of ice — but also used for protection from predators like orcas (or killer whales) and polar bears, as well as displays of dominance. Despite having these fearsome teeth, walruses mostly eat clams and other mollusks from the seafloor. They have relatively small eyes, so they depend on their sensitive whiskers to help locate food.

 

 

Climate change poses a serious threat to the walrus’ way of life. With the sea ice that these mammals depend on disappearing and temperatures rising, the future of walruses and their habitat is uncertain. Additionally, reducing sea ice is also leading to heavier shipping traffic in some parts of the walrus’ habitat as well as oil and gas exploration, which can disturb these mammals and pollute their habitat. 

 

 

Oceana campaigns to protect critical habitat and tackle the climate crisis to ensure that species, like the walrus, are able to thrive. Reducing global carbon emissions is critical to preserving the sea ice habitats that Arctic species depend on.
