Thomas Kennedy of Lake Oswego was snorkeling near Kalama Beach Park in Kihei Friday morning when he was bitten on the leg by a shark, KHON-TV, Honolulu, reported.
"I started swimming as fast as I could. ... Obviously, I wanted to get out of the water. I kept watching behind; I was concerned it would come back again," Kennedy told The Maui News.
Maui Fire Department officials said an 8- to 10-foot tiger shark was spotted in the area about the time of the attack.
Construction crew members who had been working in a nearby house called 911, the News reported.
First responders arrived quickly after the 9:40 a.m. attack, Kennedy said.
Kennedy suffered multiple lacerations to his lower left leg and thigh. He is expected to make a full recovery.
