A surfer says he's lucky not to have lost an arm when a shark bit his board off Australia's most populous state.

Justin Daniels received a single tooth puncture wound to the back of his left hand on Tuesday when the shark clamped its jaws around the board's edge off Shelley Beach, 100 kilometers (60 miles) north of Sydney.

The attack was the 13th off the New South Wales state coast this year. There were only three attacks off New South Wales last year, including two fatalities.

The 42-year-old says he was paddling his board out to sea when a 1.8 meter (6 foot) shark struck from beneath.

He says he swam back to his board and then paddled quickly to shore.
