- This zone is also known as the open ocean—it’s the oceanic water htat is not in direct contact with the shore nor the bottom of the sea floor. The Pelagic zone is also subdivided into vertical zones and even though these waters are known as the deserts of the sea, there are still a large amount of organisms that live there.
- This zone begins from the surface of the water down to where photosynthesis cannot occur because the light cannot travel that far down. The types of animals that live in this zone include tunas, sharks, and larger marine mammals. There are also some cnidarians that are found here.
- This zone reaches from 200-1000m in depth. The technical deep sea divers reach the 300m mark.
