I heard from someone today that is very talented in science. That he heard Steve I. felt it come in him but the moment he pulled it out OUCH he was dead! Why because (warning here this is a little harsh) on the bulb of the stingray there are teeth, it goes in easy but coming out it the opposite. So it just ripped his heart apart. How nasty! This was from a news report the witness of this terrible rather abrupt death happened.
