Legs are modified flippers/fins.
Lungs are modified swim bladders.
Sharks do not have swim bladders.
What do I win?
also, according to evolution, fish first developed the ability to breathe air through their skin before their fins evolved into legs.

I thought I heard somewhere that sharks would also die out of water for any decent amount of time because of their mass... Without the buoyancy of water, their own weight would slowly crush them, or something...? I have no clue where I remember hearing this.. and I may be thinking whales... but, wtf, it sounds good for sharks, too.
