Deep Sea Creatures [National Geographic Documentary 2017 HD]

The Deep sea creature refers to organisms that live below the photic zone of the ocean. These creatures 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. Most creatures have to depend on food floating down from above.
These creatures live in very demanding 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 bars. 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.

The depths of the ocean are festooned with the most nightmarish creatures imaginable. You might think you’re safe, because these critters live thousands of feet down in a cold dark abyss, but the vampire squid, which looks like a nightmare umbrella, and the frilled shark—a literal living fossil—will live on in the recesses of your mind long after you’ve clicked away. Enjoy these deep sea horrors and try to have a relaxing day afterward.

Thanks You very much

  1. Amazing nature, our planet is soo fascinating! Why not spend money on finding out what's below the ocean and not what's on the moon! The oceans a lot closer and won't cost as much to study the deepest parts of the ocean!

  2. So, with the discovery of animal fluorescence, could be possible that this mechanism could be connected with each species vision mechanism? I mean, for example, if an especies absorbs and reflects certain frequency of colour spectrum, so it may have specialized receptors for this color on it's eyes, making mating easier?

  3. They talk about ability of organisms to specialize to new environment and emanating the light by depth predators is this. But why are they saying that it's something happened occasionally. There are thousands of species living in the dark but not all of them are light emanating! Why all this wonderwork is represented as the game of chance?
