It's not every day that human appendages are found in animals. But in 1935, a 14-foot tiger shark regurgitated a human arm at an Australian aquarium and prompted a legal investigation. The shark was caught by a fisherman when it got tangled in his line, and the animal was brought it to the Coogee Aquarium Baths for show. And what a show it turned out to be. The mangled arm was vomited out along with a bird and a rat, and investigators were immediately called to the scene.
