What is found in the mesopelagic zone?
The mesopelagic zone hosts a diverse zooplankton community. Common zooplankton include copepods, krill, jellyfish, siphonophores, larvaceans, cephalopods, and pteropods. Food is generally scarce in the mesopelagic, so predators have to be efficient in capturing food.
Are there plants in the mesopelagic zone?
Mesopelagic Zone There is not enough light for photosynthesis, so plants will not be found at this zone with the exception of some possible phytoplankton, most of which has probably sunk from the higher epipelagic zone. Oceanic zone animals living here include squid, cuttlefish, wolf fish and swordfish.
What are the producers in the mesopelagic zone?
Phytoplankton are the dominant primary producers in this zone. B. The mesopelagic zone (about 200 m-1,000 m) is the twilight zone. Because there is not enough light for photosynthesis, much less energy is available to support animal life.
What are some adaptations for living in the mesopelagic zone?
Many fish of the mesopelagic zone have eyes that are outwardly different, tubular eyes that are upwardly directed are a common adaptation; this may help to see things above them that are silhouetted in the dim light.
What is the temperature like in the mesopelagic zone?
Temperature in the mesopelagic zone declines with depth from near-surface temperatures at the top of the zone to temperatures of 5°C, or about 40°F, at a depth of 3000 feet. This temperature is the same as that in your refrigerator at home. The bathypelagic zone.
What animals live in mesopelagic zone?
Animals That Live in the Mesopelagic Zone These animals include fish, shrimp, squid, snipe eels, jellyfish, and zooplankton. Mesopelagic animals play an important role in the global carbon cycle and ocean’s food chain. These organisms migrate in massive number to the oceans surface at dusk in search of food.
What is the base of the food chain in the mesopelagic?
Copepods like these pictured are the base of the ocean twilight zone food web.

What type of species thrive in the mesopelagic zone of the ocean?
Why is the mesopelagic zone called the twilight zone?
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.
What do mesopelagic fish eat?
zooplankton
Their diet consists mostly of small, free-floating organisms – zooplankton!
How much sunlight does the mesopelagic zone get?
The area between 200 and 1,000 meters (656 and 3,280 feet) is the dysphotic 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.
