Benthic Zone

What is the Benthic Zone?

The benthic zone is the bottom layer of a body of water, including the sediment surface and sub-surface areas. This zone hosts various organisms, including bottom-dwelling fish, invertebrates, and decomposers, which are adapted to live on or within the substrate.

Benthos Organisms

Benthos are organisms that live on or near the ocean floor, which is called the Benthic Zone. These creatures include crabs, sea stars, clams, sea urchins, and certain types of fish. Some benthos crawl along the ocean floor, while others, like clams and worms, burrow into the sand or mud. Many benthic organisms feed on particles and nutrients that settle down from higher layers of the ocean, making them an important part of the ocean ecosystem by helping to recycle nutrients.
