In marine fish, the total amount of salt in the blood is much lower than in seawater; the pressure of the internal environment is less than the external pressure. To explain what happens to a saltwater fish in freshwater, we must first examine the related atomic theory and diffusion. ThePets is an informational website that features articles written by qualified A sea fish can’t live within freshwater as the natural process of diffusion acts against them, while their bodies have already adapted to osmosis and saltwater living.
