1. There are two main subspecies of walrus

The Atlantic and Pacific – which both occupy different areas of the Arctic. There's thought to be around 25,000 Atlantic and around 200,000 Pacific walrus in the wild. 
 

2. They weigh a tonne

Male Pacific walruses can reach 3.6 m long and weigh over 1,500kg (that’s 1.5 tonnes!). And big is beautiful – they need fat to stay alive.

3. Both male and female walruses have large tusks

 They use these tusks to help them haul themselves out of the water and onto sea ice. Their tusks are also used for fighting with other walruses, and defence against predators. 

 

4. Mother walruses are very protective of their young

A mother will pick a calf up with her flippers and hold it to her chest if it’s threatened, diving into the water with it to escape predators. Walruses have young fairly infrequently, so it is vital for them to protect their offspring.

5. They can live to around 40 years old

And it shows. Most of them carry a vast map scars on their skin – wounds inflicted in disputes with fellow walrus during the breeding season.  

 

6. Walruses are rarely found in deep water

They seem to prefer feeding at the bottom of shallow waters, eating clams, molluscs, worms, snails, soft shell crabs, shrimp and sea cucumbers. Tasty.

7. Pacific walruses spend spring and summer feeding over a huge continental shelf

They feed on the shallow continental shelf in the Chukchi Sea. These walruses use sea ice for resting between feeding bouts, breeding, giving birth and nursing their young, as well as for shelter from rough seas and predators.

8. Atlantic walruses prefer to rest ashore 

Unlike Pacific walruses, Atlantic walruses prefer to rest ashore, as most feeding grounds in the Atlantic are closer to land.

9. Walruses are highly susceptible to disturbance and noise.

During their mass gatherings, stampedes can occur as easily spooked walruses attempt to reach the water.

10. The greatest threat to walruses is climate change

Melting sea ice means more Pacific walruses are resting on land, further from their feeding grounds. These ever growing gatherings can be deadly, especially for young calves. 

And as the Arctic opens up to more shipping, tourism, industry and noise, the Atlantic walruses are at greater threat of disturbance, and therefore stampedes. 

Climate change is driven by us, but it can be fixed by us.
