salt water
Bull sharks and River sharks are the only true sharks that live in fresh water, although there are several other species of fish that sometimes have "shark" in their informal names.on the lighter side...only wimpy sharks
It is all to do with the curvature of their claws. Alligators have short legs and so they would ruin their beautiful feet if they scraped along the bottom of the shallow end. As they pass the 50 metre mark however, the small flick at the end of their tail transforms as if by magic into a turbo jet and the forces of motion expended by this action convert the salt in fresh water rivers into the main constituent of a raspberry trifle.
Some domesticated ducks only need water to preen in, not to swim in , but yes; wild ducks do need water to swim in.
Ducks swim in lakes and rivers- mostly small bodies of water. They almost never swim in oceans.most fresh water; Ponds, lakes, rivers
ducks have to swim under water to get food because they will have no food if they dont go under water and they need water also.
Salt water has a slightly higher density, so it will be a little quicker to swim in fresh water.

for a simple answer,Yes
Because there is salt in sea water and salt makes you float better so is easier to swim.
probally fresh because no salt in mouth or eyes addition: it is easier to float/swim in seawater since seawater is denser than fresh water.
clean the tank and while you are doing that put it in a small bowl but with enough room to swim with fresh water but make sure that if it is a fresh water its in fresh water if it is salt water it is in salt water
The bull shark.
You are more buoyant in salt water than in fresh water, so it takes less energy just to stay afloat, making it easier to swim.

I don't know about health benefits, but...You are more buoyant in salt water, but fresh water feels better on the skin. salty water is the best to swim in because if your ill every year you can swim in it and you will not be ill for a year
it depends... is it a salt water or fresh water type of fish. if it is a fresh water kind there is something wrong with it but if it is a salt water kind apparently some have been found to swim backwards for no apparent reason.
