When considering aquatic habitats, many variables come to mind. Obviously, there is a continuum of salinity ranging from essentially distilled water at glacier faces and high mountain streams, to other freshwaters, to estuaries where fresh and salt waters mix, to oceans, to hypersaline environments such as the Great Salt Lake. Current is another factor; water may be still and stagnant, or flow in currents of various velocities. Currents may be unidirectional, such as in streams, or multidirectional, such as when waves wash across a beach. Aquatic habitats may occur in open water, or they may be associated with the bottom of the body of water, and both will be affected by the mechanical and chemical makeup of the local geology. All sorts of daily and seasonal temperature regimes can be expected. Aquatic habitats vary in the amount of light they receive and range in size from tiny pools at the base of a plant to the Pacific Ocean in size.

SriLakshmi11: Aquatic habitats occur at a range of scales, from a micro-habitat under a particular log to a macro-habitat such as a pool or riffle and, at the broadest scale, to the entire river system.

SriLakshmi11: Typical habitats include bed substrate such as silt, sand, clay, stone, rock; aquatic and riparian vegetation; debris from vegetation such as leaf litter, twigs and logs; areas of different water quality, depths and flow speeds such as pools, riffles/rocky rapids and backwaters. Some plants and animals require floodplain habitat and some animals need to move along the length of a river system
