The demersal zone refers to the part of the ocean or a body of water that is close to the bottom, including the seabed and the water layer just above it. This zone is significant for various ecosystems and is characterized by a distinct set of environmental conditions, such as temperature, pressure, and light availability. Demersal fish and other organisms, such as crustaceans and mollusks, inhabit this area.
