Ocean Zones

​RIP Take-Off

​OCean Zones

​

There are five distinct layers in the ocean that have their own characterstics. The layers can from the surfce longer where most ocean activities occur. ​

Some text here about the topic of discussion

​this zone is also called the sunlight zone with a dept ranging from 0-200 meters. There is ample light, photosynthesis also takes place in this zone.

​The Epipelagic ZOne

​

​Coral Reefs, Sea turtles, parrotfish, the Potugese man of war, and million of the other organisms inhabit this zone.

​​Key Facts:

​

​

​this zone is also called twilight zone and it lies 200 to 1,000 meters. this zone is cold and dimly lit. Many species produce their own light through biochemical process known as bioluminescence.

​mesopelagic

​

​cutterfish, opah, chain catsharks, and many other organisms inhabit this zone.

​key facts

​

​this si commonly known as midnight zone is fund between 1,000 to 4,000 meters below the surface of the ocean. No photosynthetic organisms cna be found there due to sunlight not reaching this zone.

​bathypelagic zone

​

​This zone has intense pressure, is dark, cold. Most of the fish living in this zone are black or red in color to defend themselves from predators in the zone above.

Dumbo Octopus, anglerfish, viperfish​

​​Subheader

also known as The Abyss and is located 4,000 to 6,000 meters. This zone is perpertual (neveer ending) darkness which takes up over 83% of the ocean

​The abyssopelagic zone

​the water along the seafloor of this zone is devoid (lacking) of oxygen resulting in organisms falling into a death trap

​The abyss

​This region of the ocean also contains a much higher concentration of nutrient salts like nitrogen, phosphorus, and silica due to large amunts of dead material

Anemone, deep-sea shrimp, and cusk eel ​

​​Subheader

​also known as the Trenches and named afteer Hades, The Greek God of the Underworld. This zone is the deepest of the region ranging from 6,000-11,000 meters and exists in a long narrow V-Shaped trenches,

​​HAdopelagic Zone

​The few organisms that are able to survice in this region like tiny-flea crustaceans called amphipods, tubeworms
