Marine areas
According to factors such as temperature, salinity and light, the ocean is divided into different zones. Along the coast of every continent, there is a strip of land under water called the continental shelf, after the shelf, there is a large slope called the slope, which extends to the deepest strip of the ocean. In the shallowest regions, where sunlight penetrates, most species are concentrated, while the deeper ones are still poorly known, the pressure down there is very high for non-adapted living beings, such as humans.
Epipelagic from 0 to 200 m The Great Barrier Reef of Australia (size: 348,700km²) is equivalent to the territory of Italy + Slovakia. Mesopelagic from 200 to 1000 m Apnea diving record. Herbert Nitsch reached over 200m. Bathypelagic from 1000 to 4000 m In 1912, the ocean liner Titanic sank at a depth of 3,800m. Abyssopelagic from 4000 to 6000 m In this region you can find the Black Devil fish, which is bioluminescent, has “light antennae” on its head to attract its prey. The females of this animal are much larger, due to the scarcity of food in the depths, when the males find them, bite their "bellies" and start to live as parasites. Haddopelagic from 6000 to 11000 m The Mariana Trench, the deepest point of the ocean, is located at 11,000 meters, inside it Everest Mount would fit and there would still be space left.
