Walruses live in very cold places like the Arctic Circle. This whiskered guy looks happy to be plunged into icy waters, or at least as happy as a walrus can look.
I learned that their tusks are actually canine teeth that can grow up to 40 inches. The tusks are used like hooks to haul their heavy bodies up onto land, for locating food on the ocean floor, in defense against polar bears or killer whales, and in dominance and mating displays. Interesting!
