Check out this report of a shark biting off a good chunk of leg from Dr. Erich Ritter - a leading "sharks are our friends" nutcase, who was recently attacked and nearly killed by one of his cuddly ocean friends...
Dr. Erich Ritter, the director of Green Marine and one of the world's leading experts on shark behavior, is recovering from the shark accident that occurred April 11, 2002, at the shark research facility on Walker's Cay in the Bahamas. After thousands of encounters with sharks without incident, Dr. Ritter was mistaken bitten by an 8 foot Bull Shark. Based on available information, the Bull Shark was going after a remora that had grabbed a piece of bait fish and then darted under Dr. Ritter. As the Bull went for the remora, it bite into Dr. Ritter's calf. Unable to release its bite, the shark tore off a substantial portion of Dr. Ritter's left calf. Dr. Ritter was immediately flown to a trauma center in West Palm Beach, Florida. He is presently in their intensive care unit, being treated for the wound. Dr. Ritter is recovering nicely, and it is anticipated that he will be hospitalized for from 4-6 weeks.
Notice they don't say that he lost his leg, nor do they admit that the Bull shark didn't spit the "mistake" out, but gladly took it as natural meal.
Normally, a wouldn't wish a shark attack on my worst enemy, but this kook really was asking for it, and with his idiotic attitude, did deserve it.
