Saltwater is formed when freshwater flows over land and the minerals in rocks are dissolved by running water and combined with the water, which eventually reaches the earth’s ocean. When it rains, the freshwater on the surface lessens the saltiness of the saltwater. Both ecosystems are completely different from one another, and fish develop different physiologies to thrive in each. Because of the salt content, saltwater is denser than fresh water. Marine water is salt water; however, freshwater is fundamentally different from marine water. Freshwater and marine aquatics cannot coexist in the same environment.
