The bathypelagic zone or bathyal zone (from Greek βαθύς (bathýs), deep) is the part of the open ocean that extends from a depth of 1,000 to 4,000 m (3,300 to 13,000 ft) below the ocean surface. It lies between the mesopelagic above and the abyssopelagic below.
Temperatures in the Mesopelagic zone range from 5 to 4 °C (41 to 39 °F). The pressure is higher here, it can be up to 10,100 kilopascals (1,460 psi) and increases with depth. [1] 54% of the ocean lies in the Bathypelagic (aphotic) zone into which no light penetrates. This is also called the midnight zone and the deep ocean.
The bathypelagic and abyssopelagic zones are aphotic, meaning that no light penetrates this area of the ocean. These zones make up about 75% of the inhabitable ocean space. [2] The epipelagic zone (0–200 metres (0–656 ft) deep) is the area where light penetrates the water and photosynthesis occurs. This is also known as the photic zone.
Every adaptation that Bathydevius has developed to live in the midnight zone, classified as the deep waters that exist between 3,300 feet (1,000 meters) and 13,100 feet (4,000 meters) below the ...
The findings are incredibly important for the understanding of ocean life in the bathypelagic zone, which lies between 1,000 and 4,000 meters deep and is the largest animal habitat on Earth, the ...
What little energy is available in the bathypelagic zone filters from above in the form of detritus, faecal material, and the occasional invertebrate or mesopelagic fish. [44] About 20% of the food that has its origins in the epipelagic zone falls down to the mesopelagic zone, [22] but only about 5% filters down to the bathypelagic zone. [40]
It lives at an extreme depth of 1,000 to 4,000 meters, or 3,300 to 13,100 feet, below the surface in the ocean’s midnight zone, creating a unique challenge for scientists who’ve worked for ...
Altogether, the pelagic zone occupies 1,330 million km 3 (320 million mi 3) with a mean depth of 3.68 km (2.29 mi) and maximum depth of 11 km (6.8 mi). [2] [3] [4] Pelagic life decreases as depth increases. The pelagic zone contrasts with the benthic and demersal zones at the bottom of the sea. The benthic zone is the ecological region at the ...
