A group of five surfers was surprised by a shark hunting down one of them off Santa Barbara. The incident occurred when Ron Takeda, a fellow foil surfer, was trailing him in a 19-mile run to test out new equipment. The video shows a fellow surfer holding a selfie stick recording the waves, with Takinga trailing him. The shark eventually stopped following a long chase. This incident comes as experts warn of more shark appearances off California due to unusually warm ocean temperatures and a potential El Niño.
