i assume "saltwarter" means saltwater. saltwater eels do not sting, they do not have anthing that can sting you. but god gave them viscious jaws, they have a very strong bite and large eels are known to have taken off divers hands. so my advice to you is not to stick your hand anywhere their jaws. which idiot wrote that? you can eat eat eels. when they're dead they don't bite.
Some animals that live primarily in saltwater need fresh water because saltwater does not absorb the necessary impurities from their metabolic systems. Salmon and some species of eels spend part of their life cycle in fresh water (where they have to retain salt) and part in the sea (where they have to balance their body salt with the saltwater around them).
