How can fish like salmon and trout survive the osmotic pressure of both fresh and salt water environments?
Salmon, for example, have evolved to survive in both fresh and salt water because of their life cycle. Salmon are born in freshwater streams, but then migrate into the ocean where they mature and spend about 1-5 years. After that, they migrate back to the same freshwater streams they were born in so they can reproduce. Their bodies have adapted to use osmoregulation to either retain or get rid of salt depending on their surroundings.
