The fascinating deep sea creatures you see above must survive in extremely harsh conditions, such as hundreds of bars of pressure, small amounts of oxygen, very little food, no sunlight, and constant, extreme cold. In this video, you’ll see “beautiful and bizarre creatures, from 40m-long jellyfish to grotesque angler fish and vampire squid.” Continue reading for more.

Most creatures have to depend on food floating down from above. These creatures live in very harsh environments such as the abyssal or hadal zones, which, being thousands of meters below the surface, are almost completely devoid of light. The water is between 3 and 10 degrees Celsius and has low oxygen levels. Due to the depth, the pressure is between 20 and 1,000 bar. Creatures that live hundreds or even thousands of meters deep in the ocean have adapted to the high pressure, lack of light, and other factors.
