Dawn of the Ocean

Alien life forms lurk in our oceans, yet more than 95 percent of their depths remain unexplored. In this documentary, we journey toward the ocean floor, where eternal darkness prevails. Oceanographers search for creatures that thrive in extreme conditions scientists once believed too toxic to support any life. Photorealistic animation brings to life primitive creatures such as the armored Dunkleosteus, a shark-devouring beast.
