Walruses are called Aiviq in Inuktitut, the language spoken by Canada’s Inuit. The walrus (Odobenus rosmarus) is a pinniped mammal. It is the only member of the Odobenidae family, a name derived from the Greek words for “teeth” and “walk”, which refers to the way walrus use their tusks to move across ice. Adult female Atlantic walruses average around 2.75 m in length and weigh around 850 kg. Males average 3 m in length and weigh around 1,000 kg.
