What are some fun facts about the deep sea?
Amazing Facts
- Approximately 98% of the ocean’ species live in, on, or just above the floor of the sea.
- The estimated number of seamounts ranges from 30,000 to 100,000.
- Seamounts are home to a breathtaking array of species (for example, over 850 species were found on seamounts in the Tasman and Coral Seas).
What is in deep sea?
This is the deep sea. Most are familiar with the surface layer, which extends down 650 feet (200 m) and receives the most sunlight, allowing photosynthetic organisms like phytoplankton to convert sunlight to energy. It is the home of pods of dolphins, schools of fish, and shoals of sharks.
What is the deep sea called?
Abyssopelagic Zone – The next layer is called the abyssopelagic zone, also known as the abyssal zone or simply as the abyss. It extends from 4,000 meters (13,124 feet) to 6,000 meters (19,686 feet). The name comes from a Greek word meaning “no bottom”.
Why is the deep sea so important?
The Deep Sea plays a major role in climate change mitigation. By storing a large part of the CO2 produced by human activities and by absorbing the heat accumulated by greenhouse effect, the Deep Sea slows down the warming of surface waters and land.
How deep is the deep-sea?
35,876 feet
The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
How cold is the deep sea?
Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.
How many deep sea are there?
The average ocean depth is 3.7 kilometers (2.3 miles). That’s 2.74 kilometers (1.7 miles) down! The average depth of the ocean is about 3,688 meters (12,100 feet).

Are there plants in the deep sea?
From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can’t take place, there are no plants, either. Animals that live in the abyssal zone feed on detritus raining down from above—or on each other.
Why are deep sea animals red?
At depth, these animals are not visible. The black animals absorb all colors of light available and the red animals appear black as well since there is no red light to reflect and their bodies absorb all other available wavelengths of light. Thus, in the deep ocean, red and black animals predominate.
Why is the sea red?
The Red Sea is the saltiest sea of all the seas that connect to the ocean without even one river meeting the sea. A popular hypotheses about the origins of the Red Sea’s name is that it contains a cyanobacteria called Trichodesmium erythraeum, which turns the normally blue-green water a reddish-brown.
