Walruses are very social creatures, and live in large herds year round. During non-breeding times, separate herds form for males and females. These herds also tend to migrate, moving from beaches to ice flows. As far as reproduction goes, females have 15-16 month gestation periods, and calves can weigh over 150lbs at birth!
Because Walruses are so massively large, their only non-human predators are Orcas and Polar Bears. Walruses were hunted for their tusks, hides, and oil for many, many years. Currently only a handful of native groups are allowed to hunt Walruses, and the numbers are carefully monitored.
