Layers of the Ocean


                 The euphotic zone in the ocean is the top section where the light    exposure is the strongest! An example of an animal that is found in this layer is the sperm whale. 
This big guy spends most of his time in the euphotic section but dives to great depths to find his dinner which is usually a giant squid.
     








           Next is the disphotic zone which starts at about 600 ft below the surface and has little light. It is also referred to as the twilight zone. No plants grow at this point in the ocean. An animal you would likely encounter at this point would be a Rattail fish. Most of the fish in this zone don't chase their food. They either stalk it or wait for it to float or swim by.



          The bottom level is the aphotic zone. At the point there is absolutely no light and water pressure can be as much as two tons per square inch. The deep sea gulper eel lives in this part of the ocean but is very rare to find. They have large enough mouths to swallow prey twice their size. This species of eel is unlike any other because of its rare mouth. To lure its prey it emits a redish glow.
