Diffusion as defined by Encarta is “the flow of energy or matter from a higher concentration to a lower concentration.” So if our freshwater fish were placed in salt water, the water molecules contained in the fish’s body would pass through the cell membranes of the fish, causing the fish to lose water.

Why can’t saltwater fish live in freshwater?

If you put saltwater fish in freshwater, it becomes even harder for a saltwater fish to locate the traces of salt needed to regulate their body cells. 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.

How are freshwater fish adapted to living in fresh water?

Fishes that live in freshwater tend to have less saline body fluids than their surroundings. There is pressure for water to move from the less saline side to the more saline side. Freshwater fish tend to gain significant amounts of water through their gills and the skin over their bodies.

What is a freshwater adaptation?
