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


The mating scene and after l.jpg

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 wherecopulation 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 thattime.
