[4] The females are diestrous, coming into heat in late summer and around February, yet the males are fertile only around February; the potential fertility of this second period is unknown. The walrus spends the cold winter months over the Bering Sea. [64] Atlantic walruses routinely also rest ashore in the summer and autumn, as feeding grounds in the Atlantic are closer to land. [98][99] Analysis of trends in ice cover published in 2012 indicate that Pacific walrus populations are likely to continue to decline for the foreseeable future, and shift further north, but that careful conservation management might be able to limit these effects. The entire pregnancy lasts about 15 months, but the baby actually grows for only 11 months. Dust. Both the orca and the polar bear are also most likely to prey on walrus calves. Advertisement. When not feeding they spend much of their time on sea-ice. Walruses use their tusks to haul themselves out of the water and onto the sea ice. [82] The walrus does not, however, comprise a significant component of either of these predators' diets. [50][51] There were roughly 200,000 Pacific walruses in 1990.
