Demersal fish is a type of fish that is primarily inhabits the lower depths of a body of water, particularly the ocean floor. The term "demersal fish" does not refer to a specific species, but rather it describes a group or category of fish based on their shared habitat preference.
These fish are adapted to life near or on the seabed, and are commonly found in coastal areas, continental shelves, and deep-sea environments. These types of fish share features that make them well-suited for this habitat, such as flattened bodies, strong pectoral fins, and specialized feeding structures. This group of species can be subdivided into 'large' and 'small' demersal fish, and includes various types of flatfish, cod, flounder, skates, and many more. Demersal fish play a crucial role in marine ecosystems as they interact with other species in the benthic (bottom-dwelling) environment.
As mentioned on the general page for Demersal fish, this group of species can be subdivided into 'large' and 'small'. Please find the full list of included species below. The impact of

Demersal fish is a month-by-month, computer generated data layer following calculations made by the ecosystem simulation (EwE). For more information on how Ecopath-with-Ecosim (EwE) works, please visit our Wiki page or visit the official EwE website at https://ecopath.org.
