What are the light 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 3 zones in the ocean?

What are the names of the 5 ocean 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 the 5 pelagic zones?
The pelagic zone is divided into epipelagic, mesopelagic, bathypelagic, abyssopelagic, and hadopelagic zones.
How many zones does the ocean have?
The ocean is divided into three zones based on depth and light level. Although some sea creatures depend on light to live, others can do without it.
What are the 5 zones in the ocean?

sunlit zone
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. Many animals inhabit this zone. Most fish live in this zone.

Which zone that gets a lot of sunlight?
euphotic
The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here.
Which ocean zone has the most sunlight?
The Epipelagic zone receives the most amount of sunlight since it’s the layer of water that forms the surface.
How many light zones can the ocean be divided into?
There are four ocean zones. The sunlight zone, twilight zone , midnight zone, and abyssal zone . The oceanic zone is subdivided into the epipelagic, mesopelagic, and bathypelagic zones. The mesopelagic (disphotic) zone, where only small amounts of light penetrate, lies below the epipelagic zone.
Where is the sunlight zone in the ocean?
The sunlight zone is the area between 0m and 200m beneath the surface of the sea and is home to endless quantities of life. The sunlight zone is where microscopic organisms are able to convert the Sun’s energy through photosynthesis.
What is the zone of the ocean that gets no light?
54% of the ocean lies in the bathypelagic (aphotic) zone into which no light penetrates. This is also called the midnight zone and the deep ocean. Due to the complete lack of sunlight, photosynthesis cannot occur and the only light source is bioluminescence.
