Deep sea creatures are actually fishes that live in the darkness below the sunlit surface waters, which is actually below the epipelagic. Some call it the photic zone of the ocean, and it is home of some rare creatures.
Humans rarely encounter deep sea creatures, because they rarely dive so deep. But a team of divers does exactly that for a BBC documentary. Showing some of the most common, but also rare deep fishes, the documentary takes you as deep into the ocean as you can handle.
The most common deep sea fish is the lanterfish, but you can also encounter frilled shark, six-gill shark, giant tube worms, vampire squid, pacific viperfish, giant spider crab and much more.
To understand how deep these divers go, the deep-sea is considered to be some 5,000 feet or 1,500 meters below the surface.
