You can tell a walrus from a seal by the long tusks protruding from their mouth. It is said that these are actually teeth that the walrus uses to pull itself out of the water, to chip off ice and to protect itself from predators. Aside from this, we can tell a walrus by its huge, flabby body which is said to be made up of a thick layer of fat called blubber. Blubber helps walruses survive in cold temperatures.
