The Riddler.

But fish DO breath. They take in water and separate the oxygen from the hydrogen and throw out the hydrogen through their gills. At least this is what I learned.

What about a black hole or space?

Some kind of fish.

  Sorry I haven't commented in a while, but Leatho Shellhound!  You are the winner!  The answer is fish!  And for any of you Middle Earth fans, that riddle was from Riddles in the Dark in The Hobbit.   I'm awesome, yes, I know.

Yes!

This thing all things devours:
Birds, beasts, trees, flowers;
Gnaws iron, bites steel;
Grinds hard stones to meal;
Slays king, ruins town,
And beats high mountain down.

[Rainshadow]

  The man who invented it doesn't want it. The man who bought it doesn't need it. The man who needs it doesn't know it. What is it?

 (Hint: This isn't from Riddles in the Dark!)

  Later:  Has no one guessed?!?!  It's actually quite an easy one!
