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. They will form dense layers according to species. Most species prefer to remain close to the coast where they are commonly found in large schools near the continental slopes. They do this to follow the similar migrations of plankton, which serve as their primary food source. Background Information: Lanternfishes are represented by 246 species and are found all around the world in oceans. Everything is spread out, and patchy. Out of all marine species, 98% of them can be found on the ocean floor, making the benthic zone the lifeblood of diversity in the ocean, comprised of mostly scavengers or detritivores, organisms that feed off of dead organic material. Salinity: Primarily freshwater, but some in brackish waters to about 20 parts per thousand [5, 20]. This isn’t the first time the region has been studied, but it’s one of the most thorough and cutting-edge attempts to see inside a realm that was once entirely hidden. With estimated global biomass of 550-660 million metric tons, fisheries around the world catch on several occasions, lanternfish attributing much of the biomass to the world’s deepest depths. The twilight zone, or the mesopelagic zone, is the region of the global oceans between 650 feet and 3,300 feet deep, and it is one of the world’s last great wildernesses. There’s the countless bioluminescent jellyfish and, one of Caiger’s favorites, the stoplight loosejaw, a fish that can perceive red light (which is the equivalent of night vision goggles in the deep sea). 2. Dysphotic Zone (Twilight Zone or Mesopelagic Zone) Also known as the twilight zone (or mesopelagic zone), light intensity in this zone is severely reduced with increasing depth, so light penetration is minimal.

Cool sea creatures like lanternfish, dragonfish, squid, and eels live in this zone. But many animals use bioluminescence in short bursts. These oblong creatures have tiny eyes, short snouts, big mouths, and jaws. After hatching, young larvae have a small number of photophores to create light. To sustainably manage fisheries in the ocean twilight zone, it's critical to understand how much overall life (or "biomass") the zone holds, and what . “It’s very dark, out of sight, and out of mind,” says Porter Hoagland of WHOI, who studies the economics and public policy that govern marine resources. Lanternfish are one of the most abundant groups of organisms in the oceans and inhabit the 'twilight' zone, the part of the ocean between 200 - 1000 metres which only a small amount of sunlight . They have been duly named after the use of bioluminescence. The common deep-sea squid Gonatus onyx eating a lanternfish in the ocean twilight zone.

According to scientists monitoring sea plastic in the eastern garbage patch of the Pacific Ocean, more than 80 plastic chips have been found in the gut. The early stages of these fishes develop in the epipelagic layer nearer to the surface, but juveniles and adults move down into the dark zone. They have a very slender, compressed body covered with silvery scales and relatively small fins. Although plentiful and plentiful, there are currently only a few commercial fungus fisheries: limited operations in South Africa, the sub-Antarctic, and the Gulf of Oman. Taken together it’s the largest animal migration on the planet. Migration patterns also depend on the age of life, gender, latitude, and season. Loud. Gelatinous invertebrates such as sea angels and sea butterflies are struggling to make their own shells in acidifying oceans, Caiger says, and whatever hurts the surface impacts the twilight zone, and vice versa. They do this to follow a similar migration to plankton, which serves as their primary food source. Researchers later realized that this was not a moving seafloor, but a mass movement of life—the nightly migration of plankton, fish, and other creatures from the twilight zone to the surface on the hunt for food. It is believed that this behavior helps to reduce competition between species. The twilight zone is also home to lanternfish, a remarkably diverse family of small mesopelagic fish with more than 250 species. the oxygen-minimum zone begins at about 500 meters depth and extends to about 1,000 meters.
