What are the 5 zones of the ocean?

The ocean is divided into five zones: the epipelagic zone, or upper open ocean (surface to 650 feet deep); the mesopelagic zone, or middle open ocean (650-3,300 feet deep); the bathypelagic zone, or lower open ocean (3,300-13,000 feet deep); the abyssopelagic zone, or abyss (13,000-20,000 feet deep); and the ...

How many zones are there in the ocean?

Which ocean zone is the coldest?

In the thermocline, temperature decreases rapidly from the mixed upper layer of the ocean (called the epipelagic zone) to much colder deep water in the thermocline (mesopelagic zone). Below 3,300 feet to a depth of about 13,100 feet, water temperature remains constant.

Where is the sublittoral zone?

adjective Ecology Geology. of or relating to the biogeographic region of the ocean bottom between the littoral and bathyal zones, from the low water line to the edge of the continental shelf, or to a depth of approximately 660 feet (200 meters).

What ocean zone do anglerfish live in?

The deep sea anglerfish, also known as the humpback anglerfish, is a medium sized (7 inches/18 cm) anglerfish that lives in the bathypelagic zone of the open ocean. Living at depths of at least 6600 feet (2000 m), this species lives its life in the complete absence of sunlight.

Where is the Mariana Trench?

The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth. According to the Exclusive Economic Zone (EEZ), the United States has jurisdiction over the trench and its resources. Scientists use a variety of technologies to overcome the challenges of deep-sea exploration and explore the Trench.

Do sharks live in the twilight zone?

Different shark species spend varying lengths of time in the twilight zone. Blue sharks spend up to an hour hunting for a meal; whale sharks can spend a few hours; and basking sharks take it to the extreme, spending up to four months feasting on twilight zone creatures before re-emerging to the sunlit surface waters.

Which zone is the hardest for animals to live in?

Deep in Darkness

It is very cold and completely dark in the midnight zone. Water pressure can be as much as two tons per square inch. Life isn't easy here and this zone has fewer organisms than the other zones. Because there is no light in this zone, some animals don't have eyes.

What is special about the twilight zone ocean?

The ocean twilight zone is a layer of water that stretches around the globe. ... 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.
