This is one helluva fish story. Aussie fishermen in Victoria accidentally ensnared a 6.5-foot-long Chlamydoselachus anguineus and had no idea what they had netted. They also couldn’t find any colleagues who had ever seen the creature before. Yet it’s one of the planet’s most primitive species and has been baring its 300 teeth for nearly 80 million years. It was swimming far above the normal depth for its species when caught, and has become the first frilled shark spotted by humans in living memory.
