What are the different domains of the marine environment?
Pelagic domain
Benthic domain
The pelagic domain is the saltwater column and is populated by pelagic organisms, such as plankton, necton, and neuston.
The benthic domain comprises the ocean floor and includes different zones according to depth, such as the supralittoral, sublittoral, and hadal zones.
The benthic domain can be divided into soft bottoms, which are rich in fauna, and rocky bottoms, which harbor flora and fauna that can attach to the substrate.
