By simply looking at the surface, sitting in a boat or standing on the shore, it's very difficult to see the amazing diversity of life that exists in the ocean.
The ocean is vast, covering a little more than 71 percent of Earth's surface. Of that, 65 percent is considered blue water (open ocean)--waters that lie beyond the coastal shallows (coastal ocean). The world of people, trees and birds is relatively flat, never extending too far above or below the ground. Oceans are different; they have an average depth of more than 2 miles and contain life nearly everywhere, even on the deepest bottoms!
Oceanic life is divided into two major categories: the benthic environment (the sea floor) and the pelagic environment (the ocean waters). The pelagic environment is further divided based on water depth.
The neritic zone is the first 200 meters (656 feet) of ocean water, which includes the seashore and most of the continental shelf. Most photosynthetic life (life that uses light enery to convert carbon dioxide and water into food), such as phytoplankton and floating sargassum, is found in this region. Zooplankton, which is the floating creatures ranging from microscopic diatoms to small fish and shrimp, also live here. Many species of whales, like the gigantic blue and humpback whales, feed almost entirely on the tiny zooplankton. These whales force seawater through baleen plates (combs of bony material that form in the place of teeth) to filter out the tiny sea creatures. The largest of all fish, the whale shark, lives off plankton alone!
Although fish are found everywhere in the ocean, the abundance of small organisms in the neritic zone provides a plentiful source of food for larger animals. Great schools of tuna and mackerel feed on squid, krill and small fish that gather where warm waters meet nutrient-rich cooler waters. The largest example, the Northern Bluefin Tuna, can grow to be more than 10 feet long and weigh over 1500lbs! Most sharks are common near the surface as well, some feeding on schools of fish, while others, including the basking and whale sharks, eat plankton.
The oceanic zone extends from 200 meters (656 feet) deep all the way down to the bottom of the ocean, which can be thousands of meters deep.
The neritic zone is a part of an ocean which is shallow, up to 200 meters in depth. It is also the section of the ocean where plants can still conduct photosynthesis.

The epipelagic ocean zone is most habitable.
The ocean floor is the most anaerobic zone in the ocean.
The photic zone of the ocean is the surface of the ocean that receives sunlight.
The epipelagic ocean zone is most habitable.
The epipelagic ocean zone is most habitable.
The ocean zone is the deep, or open ocean zone, where they swim amongst the coral and red water ;D
in what ocean zone do blue shark live in
The abyssal zone is the region of the deep ocean that is just above and on the ocean floor.
The aphotic zone is permanently dark. Organisms would need to be able to manufacture and obtain food without photosynthesis.
The Intertidal Zone, Coastal Zone, Open Ocean, Ocean Trench, Photic Zone, and Aphotic Zone. (i asked this question then found it in my textbook)
