   The ocean twilight zone is an important source of food for many marine animals, including valuable species like tuna and swordfish. It also plays an important, but little-studied role in taking carbon out of the atmosphere, which helps to regulate Earth’s climate. These two benefits alone are very important for humans, but they occur mostly ...

   Is the twilight zone a major source of food for humans? Humans are unlikely to eat anything caught from the twilight zone—the animals there are mostly small, bony fish and gelatinous organisms. However, some governments and corporations are planning to harvest animals from the twilight zone to provide fish meal for aquaculture operations.

   Humans receive two key benefits from the twilight zone: the removal of heat-trapping carbon dioxide from the atmosphere, and the support of commercially important fisheries in the surface waters. Potential future benefits include the harvest of twilight zone fish to produce fish meal for aquaculture operations or fish oil for human health supplements.

   The ocean twilight zone is a layer of water that stretches around the globe. It lies 200 to 1,000 meters (about 650 to 3,300 feet) below the ocean surface, just beyond the reach of sunlight. 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 ...

   Scientists think that the largest animal migration on Earth may take place in the Twilight Zone, every day! At dusk, phenomenal numbers of creatures – fish, squid, shrimps – rise nearer to the surface to feed, using the dark of night to avoid predators. This would take the prize from birds, who see a huge annual migration of five billion.

   Jan 22, 2020 · A new report from researchers at Woods Hole Oceanographic Institution (WHOI) reveals for the first time the unseen—and somewhat surprising—benefits that people receive from the ocean’s twilight zone. Also known as the “mesopelagic,” this is the ocean layer just beyond the sunlit surface.

   Why do animals live in the Twilight Zone?

   • Some organisms spend their lives in its shadowy depths, while others travel to and from the surface every day in the largest animal migration on Earth. Animals in the twilight zone help support the ocean’s food web and transport huge amounts of carbon from surface waters into the deep ocean, helping to regulate global climate.

   How does the Twilight Zone affect Earth's climate?

   • By migrating to and from the surface, eating, being eaten, dying—and even by pooping—organisms in the twilight zone transport huge amounts of carbon from surface waters into the deep ocean. That process, called the biological pump, plays an important role in regulating Earth’s climate.
