it depend on the density of the water . fresh water is more dense than sea water. therefor human can float on sea water easier than fresh water. divers are good at water density.
It is easier to float in salt water than in fresh water.
Salt water is more buoyant than fresh water is, because salt water is slightly more dense. -- Anything that floats in salt water will float higher than it does in fresh water. -- Anything that sinks in salt water will sink slower than it does in fresh water. -- Anything that just barely floats in salt water may possibly sink in fresh water.
Ships float in fresh water too. Only a little deeper, since fresh water is less dense than salt water.
Salt water is more dense than fresh water. So when you're in salt water you float more than when you are in fresh water
Salt water has a greater density than fresh water. So the same object will foat higher in salt water than in fresh, and some things will foat in salt water that are too dense to float in fresh water.
yes, they can survive in fresh water as well as saline water
they can if the ocean is fresh water
yes human being can't survive without fresh water
yes all puffer fish can survive in fresh water areas
no
No.

Swim
fresh
yes
No. Puffer fish can only survive in the ocean.
Sea mammals cannot survive without fresh water, but they do not have to drink fresh water in order to obtain it. They get much of their water through the food they eat and through their own bodies which remove the salts from sea water and the water in their food.
