Can dolphins or whales live in fresh water?
They don’t need to breathe in water so assuming they have enough prey I don’t see why the water’s saltinity affects them.
But then why don’t we have dolphins playing in the Mississippi river?

Good call on buoyancy! Swimming in fresh water would probably feel like us walking in knee high mud.
