Sharks can apparently have heart attacks.
Also, their hearts only have two chambers.
Lessons from the call!

More shark facts:
shark teeth are actually modified scales, which is why they form replaceable rows of teeth in the mouth.
Contrary to common belief, shark visual acuity is actually pretty good. You can often tell which sharks depend more on eyesight for hunting by the size and complexity of their eyes. Sharks with reduced eyes clearly don't need them to hunt.
Bull sharks can live in fresh or salt water, because they have awesome osmoregulation. (They're also pretty aggressive.)
