A Fiji mermaid (also Feejee mermaid) is a common feature of sideshows. It is presented as a mummified body of something, supposedly a creature that was half mammal and half fish (like a grotesque version of normal mermaid stories).The original exhibit was popularized by circus great P.T. Barnum, but has since been copied many times in other attractions, including the collection of famed showman Robert Ripley. The original exhibit was shown around the United States, but was supposedly lost in the 1860s when Barnum's museum caught fire. The exhibit has since been acquired by Harvard University's Peabody Museum of Archaeology and Ethnology and is currently housed in the museum's attic storage area.
