How many zones are there in the ocean?
five zones 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 …
What are some characteristics of the four zones of the ocean?
Marine ecosystems include four zones such as the intertidal zone, neritic zone, open ocean or bathyal zone, and deep ocean or abyssal zone. The intertidal zone is an area between high and low tides, wherein the land meets the ocean. This includes the rocky shores and beaches.
What are the 3 main zones of the ocean?
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.
What are the major zones found in the ocean?
There are three main ocean zones based on distance from shore. They are the intertidal zone, neritic zone, and oceanic zone.
Why is the ocean divided into zones?
Oceanographers have divided the ocean into zones based on how far light reaches. All of the light zones can be found in the oceanic zone. The epipelagic zone is the one closest to the surface and is the best lit.
What are the 5 vertical zones of the ocean?
There are 5 distinct photic layers of the ocean: the epipelagic zone (the sunlight zone), the mesopelagic zone (the twilight zone), the bathypelagic zone (the midnight zone), the abyss (the abyssopelagic zone), and the trenches (the hadalpelagic zone).
What is the deepest zone of the ocean called?
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.
Where is the pelagic zone?
the open sea The pelagic zone is the part of the open sea or ocean comprising the water column, i.e., all of the sea other than that near the coast or the sea floor. In contrast, the demersal zone comprises the water that is near to (and is significantly affected by) the coast or the sea floor.
What are the 5 layers of the ocean?
The ocean has five layers called zones. From the surface to the deepest part of the ocean, the zones are the epipelagic, mesopelagic, bathypelagic, abyssopelagic, and hadalpelagic zones.
Which is the largest zone in the ocean?
However, there are a few sea creatures who swim this far down to feed, such as sperm whales. In fact, being fifteen times the size of the epipelagic zone, the bathypelagic is generally regarded as the world's largest ecosystem.

How are ocean zones classified?
Two ways oceanic zones are classified are by vertical zones, the different zones found as you move from the surface of the water to the ocean floor, and horizontal zones, the different zones found moving from shore outward.
What is the largest zone in the ocean?
However, there are a few sea creatures who swim this far down to feed, such as sperm whales. In fact, being fifteen times the size of the epipelagic zone, the bathypelagic is generally regarded as the world's largest ecosystem.
Where is the twilight zone in the ocean?
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.
Are there 3 or 5 ocean zones?
The sunlight zone, twilight zone, and deep ocean are the three major zones of the ocean. The deep ocean is further divided into 3 layers which are the midnight zone, the abyss and the trenches.
Where is the abyssal zone?
The abyssal zone, also known as the abyssopelagic zone, is one of the levels into which the oceans are divided and it is found between 3,000 and 6,000 metres below the surface. In fact, the word abyssal comes from the Latin abyssalis, meaning abyss, something bottomless or extremely deep.
What are the pelagic and benthic zones?
The first major distinction is between the pelagic and benthic zones. The pelagic zone refers to the water column, where swimming and floating organisms live. The benthic zone refers to the bottom, and organisms living on and in the bottom are known as the benthos .
What are the 3 pelagic zones?
The pelagic zone is divided into zones based on light penetration from the surface: Epipelagic (sunlight; 0-200m) Mesopelagic (twilight; 200-1,000m) Bathypelagic (no light; 1,000-4,000m)
What zone do sharks live in?
Habitat. 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.

What lives in the abyssal zone?
The abyssal zone is surprisingly made up of many different types of organisms, including microorganisms, crustaceans, molluscan (bivalves, snails, and cephalopods), different classes of fishes, and possibly some animals that have yet to be discovered.
Do sharks live in the Twilight Zone?
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. The sharks in this zone feed primarily on other deep-sea creatures.
Which is the largest ocean zone?
However, there are a few sea creatures who swim this far down to feed, such as sperm whales. In fact, being fifteen times the size of the epipelagic zone, the bathypelagic is generally regarded as the world's largest ecosystem.
What is the hadal zone in the ocean?
In most areas, the ocean floor lies 4,000 to 6,000 meters (13,000 to 20,000 feet) below the surface, but deep ocean trenches can extend this depth to 11,000 meters (36,000 feet). The region extending from 6,000 to 11,000 meters is called the hadal, or hadalpelagic, zone after Hades, the Greek god of the underworld.
Whats the difference between benthic and abyssal zone?
Since the benthic zone is the zone at the bottom, it starts right at the coastline, and carries on along the continental shelf into the deep ocean. The benthic zone in deep waters is equated with abyssal plains. Organisms living in the benthic zone, particularly on the surface of oceans, are known as benthos.
What is oceanic pelagic zone?
“Pelagic zone is the region of the ocean outside the coastal areas and is also known as the open ocean.”
Where is the benthic zone?
the seafloor The benthic zone is the lowest ecological zone in a water body, and usually involves the sediments at the seafloor. These sediments play an important role in providing nutrients for the organisms that live in the benthic zone.
Which zone do whales live?
Twilight Zone This zone extends from 700 feet down to about 3,280 feet. The light that reaches this zone is pretty faint. Larger fish like, whales and giant squid dive to these depths to feed.
What zone do dolphins live in?
Bottlenose Dolphins live in the pelagic zone of the ocean, which includes those waters further from the land, basically the open ocean. The pelagic zone is generally cold.
What lives in the midnight zone?
The midnight zone is home to many different animals including the: Anglerfish, Octopuses, Vampire Squids, Eels, and Jellyfish. It is the third layer down from the top of the ocean. It is mostly dark and very cold in the midnight zone, just like the Abyssal zone we learned about yesterday.
