The ocean water column is made up of five zones: the sunlight zone (epipelagic), the twilight zone (mesopelagic), the midnight zone (bathypelagic), the abyssal zone (abyssopelagic) and the hadal zone (trenches).
What are the 7 zones of the ocean?
The 5 Ocean Zones And The Creatures That Live Within Them
- The Sunlight Zone (Euphotic Zone) The sunlight zone gets its name because this is where most of the visible light is.
- The Twilight Zone (Dysphotic Zone)
- The Midnight Zone (Aphotic Zone)
- The Abyss (Abyssal Zone)
- The Trenches (Hadal Zone)
What are the 3 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.
- Euphotic Zone (Sunlight Zone or Epipelagic Zone)
- Dysphotic Zone (Twilight Zone or Mesopelagic Zone)
- Aphotic Zone (Bathypelagic, Abyssopelagic, and Hadopelagic Zones)
What are the 2 zones of the ocean?
The ocean can be divided into two basic areas: the benthic zone or ocean floor and the pelagic zone or ocean waters.
What are the 5 main zones in the ocean?
The ocean water column is made up of five zones: the sunlight zone (epipelagic), the twilight zone (mesopelagic), the midnight zone (bathypelagic), the abyssal zone (abyssopelagic) and the hadal zone (trenches).
What are the 5 main 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.
What are the 4 marine zones?
Like ponds and lakes, the ocean regions are separated into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. Some say that the ocean contains the richest diversity of species even though it contains fewer species than there are on land.
What were the 4 types of oceanic zones?
There are four ocean zones: the Sunlight zone, the Twilight zone, the Midnight zone, and the Abyssal zone.
What are the 3 major marine life zones in an open sea?
Open Ocean
- Epipelagic zone (ocean surface to 200 meters deep).
- Mesopelagic zone (200-1,000m) – This is also known as the twilight zone, because light becomes limited.
- Bathypelagic zone (1,000-4,000m) – This is a dark zone where water pressure is high and the water is cold (around 35-39 degrees).
How many zone are 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 is the name of the first zone of the ocean?
Epipelagic Zone – The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 meters (656 feet). It is also known as the sunlight zone because this is where most of the visible light exists. With the light come heat.
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.
What are the 6 marine zones?

- Pelagic.
- Epipelagic.
- Mesopelagic.
- Bathypelagic.
- Abyssopelagic.
- Benthic.
What are the 8 zones of the ocean?
Ocean zones and what creatures live in them
- Sunlight Zone. This zone extends from the surface down to about 700 feet.
- Twilight Zone. This zone extends from 700 feet down to about 3,280 feet.
- The Midnight Zone. This zone extends from 3,280 feet to 13,125 feet.
- The Abyssal Zone.

What is the largest zone in the ocean?
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. The temperature is constant at just above freezing.
What is the deepest zone of the ocean called?
The deepest regions of the sea are called hadopelagic (Gr.: hades = underworld). The hadopelagic extends into the deep-sea trenches, down to a depth of 11,000 metres. The inhabitants of this deepest marine region include bristle worms. The ambient pressure here is around 1000 times greater than at the water 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 are the ocean biomes?
These zones are speciality areas where different marine life-forms can breed and exist. An ocean biome is mainly divided into four zones: the Intertidal zone, the abyssal zone, the pelagic zone or the open ocean and the benthic zone.
What are the 3 types of main groups of marine life?
Lesson Summary
- Three main groups of ocean life are plankton, nekton, and benthos. Plankton float in the water. Nekton swim through the water. Benthos live on the ocean floor.
- Phytoplankton are the primary producers in the ocean. They form the base of most marine food chains.
Where is the pelagic zone?
“Pelagic zone is the region of the ocean outside the coastal areas and is also known as the open ocean.”
