  • Description:
    The video is part of the Ocean Today educational video collection (sub-collection: Marine life). It has open captions and can be viewed in regular (640 x 36) or high resolution (1280 x 720). Video's transcript (narrated by Allan Peck): "NARRATOR: The Arctic Ocean and subarctic seas are home to a hefty fellow: the walrus. These beasts use sea ice for resting and giving birth. And not any ice will suffice; it has to be thick enough to support their weight, which can reach up to 4000 pounds. Their blubber serves as a layer of insulation in the cold marine environment and helps them store energy. Their flippers are hairless. The skin on them is thick and rough, providing traction on land and ice. The Latin name for the walrus translates as "tooth-walking sea horse." You can understand why. Walruses use their long ivory tusks to haul their heavy bodies up onto the ice, to forage for food, and to defend against predators. The main role of the tusks, however, is a social one. Walruses use them in their herd for dominance and mating displays. Guess they gotta look cool in this type of climate. And that's life with the ice for walruses."
