Why Don't the Sea Fish Taste Salty???
Have you ever eaten sea fish? grilled or fried? Even eaten row? What about its taste?

Sea water is also mentioned as saltwater. The fish have a very direct and interconnected osmotic
relationship with the surrounding water. Their gill-membrane is an osmotic filter through which oxygen and other dissolved elements pass freely. The saltwater fish will die fairly quickly in freshwater, and vice versa.

Saltwater fish have evolved fewer mechanisms for adjusting to instability salinity of sea water and generally more susceptible to chemical fluctuations in the water where they live. Saltwater fish and freshwater fish have about the same amount of salt in their bodies, and this is similar to most other complicated animals on the

earth. This concentration is about the concentration of the early seas where life originated.

The oceans are saltier now, so they are saltier than the fish. Water tends to move through membranes toward the higher concentration of salt (osmosis), so freshwater fish are constantly urinating to
get rid of the extra water, while saltwater fish drink a lot of water and excrete the salt through specialized organs on their gills.

One of the biggest energy demands on fish is osmoregulation to control their salt content.
So, we can infer that the ability to regulate osmotic pressure by the "pump" is to get rid of excess salt contained in salty water.
