The mesopelagic zone (Greek μέσον, middle), also known as the middle pelagic or twilight zone, is the part of the pelagic zone that lies between the photic epipelagic and the aphotic bathypelagic zones. [1]

Mar 28, 2023 · The Abyssopelagic Zone (or abyssal zone) extends from 4,000 meters (13,100 feet) to 6,000 meters (19,700 feet). It is the pitch-black bottom layer of the ocean. The water temperature is constantly near freezing, and only a few creatures can be found at …

Jul 3, 2019 · The mesopelagic zone extends from 200 to 1,000 meters (660-3,300 feet) below the surface of the ocean. This area is known as the twilight zone, as it sits between the epipelagic zone, which receives the most light, and the bathypelagic zone, which receives no light.

Sep 29, 2023 · Also known as the midwater or mesopelagic, the twilight zone is cold and its light is dim, but with flashes of bioluminescence—light produced by living organisms. The region teems with life.

The mesopelagic zone refers to the oceanic layer extending from 200 to 1000 meters below the surface, characterized by limited sunlight penetration and a critical role in the global carbon cycle and marine food webs.

The mesopelagic zone is sometimes called the twilight zone because it is a middle zone of the ocean, found between lighter and darker areas, similar to the twilight time of day. It is a layer of water stretching around the whole globe .

The ocean water column is made up of five zones: the sunlight zone (epipelagic), the twilight zone (mesopelagic), the midnight zone (bathypelagic), the abyssal zone (abyssopelagic) and the hadal zone (trenches). The upper layer of the ocean is known as the sunlit, or euphotic, zone.

Below this zone lie the mesopelagic, ranging between 200 and 1,000 metres, the bathypelagic, from 1,000 to 4,000 metres, and the abyssalpelagic, which encompasses the deepest parts of the oceans from 4,000 metres to the recesses of the deep-sea trenches.
