- In the deep sea, since there is almost no light, many organisms produce their own light, called bio-luminescence.
- If organisms cannot produce their own light then they have large eyes that are able to detect the slightest light. - The deepest point on earth is 11 kilometer deep in the Mariana Trench, near the Mariana Islands. - The fish that lives in the deepest part of the sea can live up to a depth of 8368 meters. - We have only discovered a fraction of the organisms of the deep sea. - The largest deep sea fish is called Greenland shark.
