Why can saltwater fishes only live in salty water?

  • To answer the question in your thread title, the reason why only saltwater fish can live in saltwater is due to them being able to process the salt through their organs/gills. There are some brackish, and very few freshwater fish that can live in saltwater (they have a special organ that can allow them to process saltwater), but other fish would slowly die due to them not being able to separate and process the salt in the water.

    Doesn't that answer the question of why freshwater fish can only live in freshwater more than why saltwater fish can only live in saltwater?
