深海：深渊之光 (2016)

In a huge submarine canyon in California's Monterey Bay, there is an illuminating twilight zone. It is a world of countless exotic creatures, including sparkling jellyfish and deep sea fish that give off flashes. Using an ultra-high sensitivity 4K camera specifically developed for deep sea filming, together with experts in the field, Lights in the Abyss captures bioluminescent creatures in their natural habitat, deep in the Pacific Ocean.
