There are 400 known fish species living in Arctic seas and adjacent waters, most living on or near the bottom. So, based on global fisheries and the overall biodiversity of coral reef ecosystems, the Pacific Ocean wins for most marine life.
What ocean zone do most fish live in?
Sunlit Zone
Sunlit Zone: This is the top layer, nearest the surface.
It is also called the euphotic zone. Here there is enough light penetrating the water to support photosynthesis. Because photosynthesis occurs here, more than 90 percent of all marine life lives in the sunlit zone. The sunlit zones goes down about 600 feet.
Which ocean contains the most fish?
the Pacific Ocean
Among these oceans, the Pacific Ocean is considered the biggest ocean that also contains the most number of fishes and other aquatic organisms.
Which ocean zone has the most animals?
The epipelagic zone reaches from the surface of the ocean down to around 650 feet. This is the zone most exposed to light, and as such is host to the highest concentrations of the ocean’s life. There are thousands of animals that roam this zone, including dolphins, most sharks, jellyfish, tuna and corals.
What are the 3 main ocean zones?
The ocean is generally divided into three zones which are named based on the amount of sunlight they receive: the euphotic, dysphotic, and aphotic zones.
- Euphotic Zone (Sunlight Zone or Epipelagic Zone)
- Dysphotic Zone (Twilight Zone or Mesopelagic Zone)
- Aphotic Zone (Bathypelagic, Abyssopelagic, and Hadopelagic Zones)
What fish live in the abyssal zone?
These include the anglerfish, cookiecutter shark, frill shark, viperfish, bristlemouths, lanternfish, and flashlight fish. Other types of animals found in the abyssopelagic zone include deep-sea jellies, sea stars, deep-sea shrimp, and the dumbo octopus.
What fish live in euphotic zone?
The ocean life in the Euphotic zone include sharks, jellyfish, sea turtles, coral, and zooplankton. The reason why there are so many various life in this zone is because of its access to sunlight.
Where are most fish found?

|---|---|---|
| 1 | China | 11.5 million tons |
| 2 | Peru | 8.26 million tons |
| 3 | Chile | 4.89 million tons |

Which ocean is the best for fishing?
Pacific Ocean
The Pacific’s greatest asset is its fish. The shoreline waters of the continents and the more temperate islands yield herring, salmon, sardines, snapper, swordfish, and tuna, as well as shellfish.
Do most fish live near coasts?
Coastal fish are the most abundant in the world. They can be found in tidal pools, fjords and estuaries, near sandy shores and rocky coastlines, around coral reefs and on or above the continental shelf.
In which zone do you think the majority of ocean animals live Why?
Of the open ocean zones, most life is found in the epipelagic zone. This is where light is able to penetrate the ocean, allowing for photosynthetic processes to take place. It extends roughly 200m or 650 feet below the surface.
What zone do sharks live in?
Deep sea sharks live below the photic zone of the ocean, primarily in an area known as the twilight zone between 200 and 1,000 meters deep, where light is too weak for photosynthesis. This extreme environment is limited in both sunlight and food.
What ocean zone is the Titanic in?
The Titanic lies at 3,800 meters or about 12,500 feet. This area of the ocean is known as the Bathyal zone. The average temperature is 39° F. The pressure at this depth is 5,850 pounds per square inch.
Which ocean zone has the most nutrients?
The neritic zone is the region of shallow water (200 meters depth) above the continental shelf where light penetrates to the sea floor. Due to the abundant supply of sunlight and nutrients in this zone, it is the most productive ocean zone supporting the vast majority of marine life.
What is the deepest ocean zone?
hadalpelagic zone
The deepest zone of the ocean, the hadalpelagic zone extends from 19,700 feet (6,000 meters) to the very bottom at 36,070 feet (10,994 meters) in the Mariana Trench off the coast of Japan.
Are there fish in middle of ocean?
Oceanic epipelagic fish can be true residents, partial residents, or accidental residents. True residents live their entire life in the open ocean. Only a few species are true residents, such as tuna, billfish, flying fish, sauries, pilotfish, remoras, dolphinfish, ocean sharks, and ocean sunfish.
What is the deepest ocean fish?
The fish that currently holds the depth record is a species of cuskeel (family Ophidiidae) called Abyssobrotula galatheae. This 20 cm long fish has been collected from the Puerto Rico Trench at a depth of 8,370 m (27,455 feet).
What is the rarest deep sea fish?
Discovered in 1976, the megamouth shark (Megachasma pelagios) is one of the rarest fish in the world. Weighing on average 1,700 pounds, and measuring around 16 feet long, the megamouth is known for its large, barrel-shaped mouth.
What lives in the photic zone?
Life in the photic zone
Ninety percent of marine life lives in the photic zone, which is approximately two hundred meters deep. This includes phytoplankton (plants), including dinoflagellates, diatoms, cyanobacteria, coccolithophores, and cryptomonads. It also includes zooplankton, the consumers in the photic zone.
