Life on the Arctic Deep Sea Floor. Animals that live on the sea floor are called benthos. Most of these animals lack a backbone and are called invertebrates. Typical benthic invertebrates include sea anemones, sponges, corals, sea stars, sea urchins, worms, bivalves, crabs, and many more.

What is found in the benthic zone?
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.
What is common in all benthic zones?
The benthic zone refers to the ecological zone located at the bottom of any marine or freshwater body, such as a river, ocean, lake or pond. ... On account of the depths it can reach, the benthic zone is usually characterized by low temperature, high pressure and minimal sunlight.
Why do animals live in the benthic zone?
Although this zone may appear barren, it plays a vital role in the health of aquatic ecosystems. Tiny, microscopic benthic organisms live in this zone and act as a source of food for bottom feeding animals. Benthic organisms are very important as they are good indicators of water quality.
What is benthic life?
Benthos (from Ancient Greek βένθος (bénthos) 'the depths (of the sea)'), also known as benthon, is the community of organisms that live on, in, or near the bottom of a sea, river, lake, or stream, also known as the benthic zone.
Where does a benthic fish live?
Benthic fish (also known as demersal) are fish that live on the bottom of seas or lakes. The diversity of marine life is most obvious on the bottom where animals have adapted to a multitude of niches and with extremely diverse looks and behaviour.
What animals and plants live in the benthic zone?
Typical benthic invertebrates include sea anemones, sponges, corals, sea stars, sea urchins, worms, bivalves, crabs, and many more. Recent research indicates that the diversity of species living in the deep-sea may rival the species richness found in tropical coral reefs!
What are benthic plants?
Benthic habitat map for Pacific Island Territories. The term benthic refers to anything associated with or occurring on the bottom of a body of water. The animals and plants that live on or in the bottom are known as the benthos.
What animals live in the euphotic zone?
The Euphotic zone is characterized by its many diverse ocean life. The ocean life in the Euphotic zone include sharks, jellyfish, sea turtles, coral, and zooplankton. The reason why there are so many various life in this zone is because of its access to sunlight.
What organisms are benthic?
The word benthos comes from a Greek term meaning “depths of the sea.” Benthic communities are complex and include a wide range of animals, plants and bacteria from all levels of the food web. Clams, worms, oysters, shrimp-like crustaceans and mussels are all examples of benthic organisms.
What could you find in the benthic zone of a lake?
The benthic zone is region of a body of water (lake, river, or ocean) that is near the bottom. It includes the surface and some of the sub-surface layers of the sediment. The sediment can sand, mud, rocks, coral, among other substances. Benthos are organisms living in the benthic zone.
How do organisms that live in the benthic zone obtain food for energy?
Many benthic organisms, including filter feeders like hard clams, bay scallops, and mussels, obtain their food by taking in seawater. As the water flows through their bodies, sediments, organic matter, and pollutants are filtered out and ingested.
Are coral reefs in the benthic zone?
The benthic zone is one of the ecological regions of a body of water. ... Some benthic zones, such as areas of coral reefs, kelp forests, and eelgrass beds, help to buffer wave action along coastlines, providing storm protection (CSC 2008).
Where does plankton live?
Plankton are a collection of tiny organisms that live at and beneath the surface of lakes, rivers, ponds, and oceans across the planet. They're named for the Greek word planktos, meaning to drift or float.
Is a jellyfish a plankton?
Jellyfish are plankton—they're drifters. Usually we think of plankton as being tiny, and many of them are, but plankton just means living things in the water that can't fight a current, which includes floating jellies.
