Can sharks live in fresh water?
Their ability to tolerate freshwater is rooted in salt retention Sharks must retain salt inside their bodies Without it, their cells will rupture and cause bloating and death Given this requirement, most sharks cannot enter fresh water, because their internal salt levels would become diluted
Why can’t freshwater fish live in saltwater?
On the other hand, freshwater fish can’t survive in the ocean or saltwater because the seawater is too salty for them The water inside their bodies would flow out their cells, and they wiil die of dehydration Both processes are called Osmosis
What happens if you put goldfish in saltwater?
