Walruses By: Katy Erdle and Kerry Carlisle

2 The life of a Walrus There are 2 walrus subspecies that exist today one is the Pacific and the other is the Atlantic Walrus. A Walrus lives around years. The age of a walrus can be estimated by slicing a section of the cheek tooth and counting the layers. The total population of Walruses today is estimated to be around 250,000. The Walruses scientific name is Odobenus rosmarus.

3 Walruses living quarters!
Walruses live in very cold water. They like it where the air temp. is -15 to +5 degree C. Walruses spend about 2/3 of their lives in water. They also love to lay on the ice in the artic. Walruses have a thick layer of blubber to keep warm.It is about 15cm thick.

4 Walruses appetite and birth!
A female walrus takes 1 year to develop its young before birth after mating. A walrus weighs lbs at birth. A walrus can weigh up to 3,000 lbs. at full growth. And it can get up to 8-12 ft. in length. A Walrus eats bivalve mollusks such as clams. They will also eat worms, snails, squads, and crabs.

5 Facts about Walruses reproduction!
Most male Walruses are mature at 8-10 years old. Successful reproduction is probably around 15 years. Most females are sexually mature at 5-6 years old. Most mating occurs December-March. A male Walrus is called a Bull A female walrus is called a cow. A baby Walrus is called a calf

6 The Mating scene and after!
A Bull displays visually and vocally from the water while the female rests. The display includes teethclacking, clanging bell-like sounds, and whistles. The female or cow then joins the Bull and that is where copulation takes place. After the mating season the bulls return to all- male herds. The calf is born a year later. The calf stays with it’s mother up to 2 years maybe longer, if the mother does not have another calf in that time.
