A 13-year-old boy cycled home after being bitten by a shark while surfing off a beach in western Australia Saturday, reports said. The boy had small puncture wounds on his right leg and was treated by a lifeguard before he hopped on his bike and went home, dpa reported. The incident occurred about 85 kilometers south of Perth. Police said the shark was about 2 meters long and probably mistook the boy's leg for a fish.
