A mermaid gaff, also called a fiji or feejee mermaid, is the torso and head of a juvenile monkey sewn onto the back half of a fish. They were common in sideshows and were advertised as mummified, real specimens of mermaids. The first one in the Western world dates back to 1822 when an American sailor bought the “original” fiji mermaid from Japanese soldiers. Fiji mermaids, however, were popular in Japan long before this. It was then given to P.T. Barnum, who used it in his sideshow.
Fiji mermaids are probably the most well-known taxidermy gaff after the jackalope, which is why we would like to add it to our collection.
