This photo, released by the Awashima Marine Park in Numazu, south of Tokyo January 24, 2007, shows a frilled shark, rarely seen alive because its natural habitat is 600 metres or more under the sea. This primitive shark was caught and filmed at the Japanese marine park after a call was received from a fisherman at a nearby port on Sunday when he came across the odd-looking eel-like creature with a mouthful of sharp teeth.
