The fish species that spend some or all of their lives in freshwater is simply known as freshwater fish. All are freshwater fishes whatever in rivers and whatever in lakes, and with a slight salinity, less than 1.05%. These environments may differ from maritime conditions in dozens of ways, the most obvious being the difference in levels of salinity, though to survive in freshwater, the fish need a range of physiological adaptations.
Almost 42% of all known species of fish are found in freshwater. This is mainly due to the rapid speciation that the scattered habitats make possible.
