What is the neritic zone ecosystem?

Neritic zone, shallow marine environment extending from mean low water down to 200-metre (660-foot) depths, generally corresponding to the continental shelf. Neritic waters are penetrated by varying amounts of sunlight, which permits photosynthesis by both planktonic and bottom-dwelling organisms.

The neritic zones in tropical climates, like the Great Barrier Reef in Australia, are home to thousands of species of sea life, such as coral, sharks, and sea snakes that are found nowhere else in the world. Northern neritic zones are also flourishing with sea life, including sea otters, whales, and the giant octopus.

One may also ask, what are some animals that live in the neritic zone? Organisms. A diverse variety of organisms make the neritic zone a permanent home. Some of the most well-known are crabs, shrimp, starfish, scallops and sea urchins. Other species, such as different types of cod, tuna, flatfish and halibut, hang around at the edge of the continental shelf.

Also to know is, do sea turtles live in the neritic zone?

Sea Turtle Glossary Of, relating to, or inhabiting the shallow water, or nearshore marine zone extending from the low-tide level to a depth of 200 meters. The neritic zone is populated by benthic organisms because of the penetration of sunlight to these shallow depths.

What are the two types of neritic ecosystems?

Water environment is divided into two major ecosystems: Neritic Zone – The passively drifting Algae (Phytoplankton) is dominant in the Neritic Zone. It extends from a high tide mark to the continental shelf.


  • Mangroves.
  • Lagoons.
  • Estuaries.

What plants are in the neritic zone?

Plants found in the neritic zone: Kelp forests, Plankton, Seaweeds, Coral reef plants, and Algae.

Where is the neritic zone located?

The neritic zone is the region of shallow water (200 meters depth) above the continental shelf where light penetrates to the sea floor. Due to the abundant supply of sunlight and nutrients in this zone, it is the most productive ocean zone supporting the vast majority of marine life.

How big is the neritic zone?

The neritic zone receives ample sunlight for organism to thrive. In marine biology, the neritic zone (which is also known as the coastal ocean, the coastal waters, or the sublittoral zone) of the ocean refers to a shallow region that has a depth of about 660 feet.

What lives in the benthic zone?

Macrobenthos comprises the larger, visible to the naked eye, benthic organisms greater than about 1 mm in size. Some examples are polychaete worms, bivalves, echinoderms, sea anemones, corals, sponges, sea squirts, turbellarians and larger crustaceans such as crabs, lobsters and cumaceans.

What is Epipelagic zone?

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 are the conditions in the oceanic zone?

The Oceanic zone extends from the edge of the continental shelf over the continental slope to the ocean floor beyond. It begins where the water is over 200 meter (656 feet) deep. This zone contains deep trenches, volcanoes, and ocean basins.

What does Epipelagic mean?

Definition of epipelagic. : of, relating to, or constituting the part of the oceanic zone into which enough light penetrates for photosynthesis.

How much light is in the neritic zone?

The deeper into the ocean sunlight travels, the more diluted it becomes; at 3,000 feet, there is no sunlight. About 90% of all marine life exists in this sunlit zone and all of the coastal ocean zone is included in this.

How deep is the oceanic zone?

660 feet

Why do sea turtles live in the Epipelagic zone?

While most sea turtles stay in the epipelagic zone, leatherbacks have been recorded diving down into the bathypelagic zone. The upper portion of the epipelagic zone receives sunlight that drives photosynthesis in microscopic floating plants called phytoplankton.

How deep is the benthic zone?

In oceanic environments, benthic habitats can also be zoned by depth. From the shallowest to the deepest are: the epipelagic (less than 200 meters), the mesopelagic (200–1,000 meters), the bathyal (1,000–4,000 meters), the abyssal (4,000–6,000 meters) and the deepest, the hadal (below 6,000 meters).

What lives in the abyssal zone?

Animals in this zone include anglerfish, deep sea jellyfish, deep sea shrimp, cookiecutter shark, tripod fish, and abyssal octopus also known as the dumbo octopus. The animals that live in this zone will eat anything since food is very scarce this deep down in the ocean.

Is plankton a fish?

Plankton are the diverse collection of organisms that live in large bodies of water and are unable to swim against a current. The individual organisms constituting plankton are called plankters. They provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales.

Why is the neritic zone rich in life?

Why is the neritic zone particularly rich in living things? Sunlight can easily pass through the shallow water, photosynthesis can occur. This allows many large schools fish feed on algae and coral reefs may form provide homes for wide array of fish.
