Why is it that salt water animals do not survive in fresh water environment?
The various species of fish found in oceans, lakes, rivers and streams have evolved over millions of years and have adapted to their preferred environments over long periods of time. Fish are categorized according to their salinity tolerance. Fish that can tolerate only very narrow ranges of salinity (such freshwater fish as goldfish and such saltwater fish as tuna) are known as stenohaline species. These fish die in waters having a salinity that differs from that in their natural environments. The only fish I know of that lives in both is Pacific salmon. Salmon are born and they reproduce in the safety of freshwater but spend the rest of their lives in the oceans. This type of fish (fresh and salt water) are called anadromous.

Take a freshwater fish and put it in a saltwater environment and the higher density of the water will generally crush the internal organs of the fish.

What are facts about salmon?
1. Salmon migrate up to 4,000 miles from the ocean to freshwater areas to spawn (or lay eggs). They also must swim against very strong ocean currents just to reach freshwater, and then swim upstream against the powerful flow of the river. Additionally, they must leap clear of the water to get above falls, and do all this while avoiding predators - who know they are there and want to catch and eat them. They do all this only to die only minutes after spawning.They are healthy fish.2. They are the state fish of Alaska.salmon(s) Live in salt water, they also migrate 4,000 miles every year,they are pinkish silver,and they are always traveling on the tidle waves:)salmon(s) Live in salt water, they also migrate 4,000 miles every year,they are pinkish silver,and they are always traveling on the tidle waves:)
