Walrus Fact File
Size: Adults can reach up to 3.5m long and weigh 1.5 tonnes! Males are larger than females and the Atlantic subspecies is 10-20% smaller than the Pacific
Distribution: Atlantic individuals inhabit coastal areas from north-eastern Canada to Greenland, while the Pacific subspecies inhabit the northern seas off Russia and Alaska, migrating seasonally from their southern range in the Bering Sea — where they are found on the pack ice in winter — to the Chukchi Sea
Diet: They prefer to feed in shallow waters and eat clams, molluscs, worms, snails, shrimp and sea cucumbers
Behaviour: These marine mammals are extremely sociable, prone to loudly bellowing and snorting at one another, but are aggressive during mating season
IUCN Status: Vulnerable. Their current population trend is unknown but their biggest threat is believed to be climate change. Walrus rely on pack ice while giving birth and aggregating in the reproductive period. In addition, they are highly susceptible to noise, and are still harvested for their tusks
