The calves are dark gray-brown in color when born.Walrus change from pink-to-cinnamon brown to a lighter shade when it gets into cold water because it's blood vessels get smaller. Walrus are able to adjust to the surrounding temperatures with their blood circulatory system. When they get hot their blood is pumped to its blubber and skin and it gets cooled by the air or the water. When they're cold they can reduce the blood flow to the skin and blubber to save heat.

Population and they're habitat


more thn than 200,000 walruses in the same area at the same time in 1990. Now the population in very low and it is around the 45,000. Walruses live in the Arctic.,North Atlantic, North Pacific Oceans. Th
e oceans are cold so they have a tendency to stay up north because its colder up there and is near the north pole. They swim near the coast line were they like to stay at. In the spring time they float on ice to keep close to shore.

Other Walrus facts



  • Walruses spend about two-thirds of their lives in the water. Highly social in nature, huge herds of walruses haul out (leave the water to get on land) on sea ice to rest and bear their young. Most walruses live where the air temperature is about -15 degrees F to 5 degrees C.
  • The primary functions of the walruses' prominent tusks seem to be aiding in hauling out on ice and rocky shores and in establishing social dominance.
Breeding Mates January-February; 1 calf born mid-April to mid-June of following born weighs 100-150 lb (45-68 kg).

  • Walruses produce bell-like sounds under water.
  • Tactual communication occurs through body contact.
  • Walruses herd in groups to stay close so they won't loose each other.
  • Male Walruses may get in fights with other male Walruses over a female Walrus, then attack eachother with their masive tusks by stabbing eachother.
