Blue Planet II

Creatures that live in volcanic hot spots on the ocean bed, areas that reach temperatures hot enough to melt lead and which may hold the secrets behind all life on Earth. Other strange creatures from the depths of the sea include bone-eating worms, fish that walk rather than swim, and hordes of squid. Plus, footage of sharks in a feeding frenzy over the dead body of a whale and the wildlife of the Midnight Zone in the Pacific, an area that never receives any natural light, forcing creatures to rely on their own bioluminescence
