Walrus Skin Weighs A Lot

As babies, walruses can gain about 1 kilogram (2 lbs) every day. Males grow to be larger than the females, and their tusks-which are their canine teeth-can reach lengths of 1 meter (3 ft 3 in). Males wield these tusks in fights for dominance, but females have them too, and both sexes use them to hoist themselves out of the water.
