The profundal zone is a deep zone of a body of water, such as an ocean or a lake, located below the range of effective light penetration. A body of water is any significant accumulation of Water, usually covering the Earth or another planet An ocean (from Greek, ''Okeanos'' (Oceanus) is a major body of saline water, and a principal component of the Hydrosphere. A lake (from Latin lacus) is a Terrain feature (or Physical feature) a body of Liquid on the surface of a world that is localized to the This is typically below the thermocline, the vertical zone in the water through which temperature drops rapidly. The thermocline (sometimes metalimnion) is a thin but distinct layer in a large body of water such as an ocean or lake in which temperature changes more rapidly with depth Temperature is a physical property of a system that underlies the common notions of hot and cold something that is hotter generally has the greater temperature The lack of light in the profundal zone determines the type of biological community that can live in this region, which is distinctly different from the community in the overlying waters. The profundal zone is part of the aphotic zone.
