It's not like they breathe through gills. They breathe through a blowhole when they surface.

But their skin, their blood, and their body chemistry are all adapted to constant contact with salt water. I find it difficult (but not impossible, if there's someone around with actual expertise) to believe that none of that would be thrown off in a fresh-water environment.

Well........we are adapted to "constant contact" with air but we don't melt when we go swimming in water. I'm no marine biologist, but I don't think a few days in fresh water would be all that harmful to a dolphin.

Im not a dolphin expert but there are sweet water species. It's not one species like most people think.
