Doctor Attacked By 12-foot Tiger Shark In Hawaii

A Kansas doctor who fought off a 12-foot tiger shark last week in Hawaii described seeing a "dark gray cloud" in the water that kept getting bigger seconds before the fearsome fish ripped into him.

"I just saw a dark gray cloud and I didn't know what it was," 58-year-old Ken Grasing told KCTV. "The cloud was getting bigger, and eventually I could see it was a shark. I said, 'Oh no! This is a shark. This is a shark attack.'"

Grasing, a physician from Overland Park, Kansas, was snorkeling Wednesday with his family in 4 feet of water in Hapuna Bay off the Big Island when the massive shark attacked him, according to media reports.

Grasing suffered deep cuts to his left forearm and a gash on his left thigh, according to the station. He reportedly struck the shark in the head with his right hand as it circled around him -- saying it felt like hitting a wall.
