A circumpolar marine animal whose habitat includes Arctic and subArctic areas, the walrus is known for its large flippers, long whiskers, and of course, really big tusks. The walrus species includes three subspecies: Atlantic walruses, Pacific walruses, and (debatably) Laptev walruses. The only species of walrus we see are Atlantic walruses, and we find them in eastern Greenland and Svalbard during our Arctic cruise season.
