What is the Rarfotic Zone? The ocean area is simply the area of the ocean where the depth of water in the ocean drops below 656 feet to the open ocean.

Within the area, there are several features, such as cracks that are sometimes deeper than the height of Mount Everest.
Other features that can be found in the area include things like volcanoes and ocean basins. In this area, there are few species due to the unwanted environment.
Subzones of the ocean
Until recently, there have been three main subdivisions known and understood from the ocean area. These zones are the batipelágica, mesopelágica and epipelágica zones (zone illuminated by the sun).
The three are classified according to the amount of sunlight that each zone receives. As the alternative name suggests, the epipelagic zone receives a lot of sunlight for photosynthesis to occur.
Temperatures here range from 104 ° F to 27 ° F. In terms of depth, it varies from the surface of the ocean to depths of around 660 feet.
Also known as the dyspotic zone, the mesopelagic zone, which is located below the epigelagic zone, receives some sunlight compared to the epigelagic zone. Sometimes, this area is also known as Twilight Zone because of the low sunlight that is similar to twilight.
In this area, temperatures range between 41 ° F and 39 ° F. In addition, there is a high pressure that can reach 10,100,000 Pa. This area begins where the epigelagic zone ends at 660 feet and ends at a depth of about 3,300 feet. .
The remaining zone, the batipelágica zone, has approximately 90% of the ocean. Also known as the afotic zone, this zone receives no light at all. For this reason, it is also known as the midnight zone or the deep ocean.
The lack of sunlight obviously means that photosynthesis is impossible. The only source of light comes from bioluminescence. Water pressure is even higher here with extremely cold temperatures ranging from 32 ° F to 43 ° F. This area starts at a depth of 3,300 feet to a huge 13,000 feet down.
The rarfótica zone
Recently, in 2018, the University of Oxford discovered a new ocean area that is known as the raripotic zone or the rare light zone.
The area extends from approximately 226 feet to 984 feet according to Oxford researchers. As things stand, it is not clear how the new area will affect the classification of the other main areas, as they seem to overlap.
100 species have been discovered, including miniature crustaceans known as tanaids, from previously undiscovered organisms that reside in the new area. Other species include new species of algae and black coral with heights of about six feet.
An example of a species of newly discovered fish is the Haptoclinus dropi, which was named after the Smithsonian deep reef observation company.
