A surfer was not injured after a shark bit into his surfboard during an attack off a beach in San Mateo County over the weekend.

Luckily for one California surfer, a shark swimming in San Mateo County waters over the weekend managed to get only a sample of his surfboard. Jens Heller was about 100 yards offshore at Montara State Beach sitting on his board Saturday when the shark attacked, according to reporting from the San Francisco Chronicle.
