My research found numerous newspaper accounts of shark attacks on scuba divers. Many of these were great white sharks who attacked with varying degrees of ferocity. On one occasion a diver was able to get away with the shark only jostling his legs. However, most of the incidents were manglings, and others involved death. I've also profiled a group of English divers who attempted to set a world diving depth records off Santa Catalina Island, in 1962.
