The Fiji Mermaid: Barnum’s Greatest Hoax
The Fiji Mermaid: P.T. Barnum's Famous Hoax Explained
The Fiji Mermaid, also spelled Feejee Mermaid, is one of the most famous hoaxes in American sideshow history. A shriveled, nightmarish figure usually described as a manufactured “mermaid” made from monkey-like and fish-like parts, it drew enormous crowds to P.T. Barnum's American Museum in the 1840s. People paid to see it even after the press called it a fake.
That's the thing about a great hoax. You don't need believers. You just need the curious.
Fiji Mermaid at a Glance
- What it was: A fabricated sideshow “mermaid,” usually described as a monkey-like upper body combined with fish parts and crafted materials.
- Also known as: Fiji Mermaid, Feejee Mermaid, FeJee Mermaid, and Barnum’s Fiji Mermaid.
- Most famous promoter: P.T. Barnum, who used staged expertise, planted publicity, and public controversy to turn the object into a sensation.
- Era: Most famous in America during the 1840s, though gaff mermaid specimens and “monkey-fish” curiosities circulated before and after Barnum.
- Why it matters: The Fiji Mermaid shows how hoaxes, sideshow culture, fake specimens, museum curiosities, and monster folklore can feed each other.
What Was the Fiji Mermaid?
The Fiji Mermaid was a gaff, a fabricated curiosity made to look like the dried remains of a creature that was part human or primate and part fish. Surviving Feejee Mermaid-style specimens are not all built the same way. Some have been described as monkey-and-fish composites, while museum investigations of similar “merman” figures have found fish parts, papier-mâché, clay, fabric, teeth, claws, and other crafted materials.
That uncertainty matters. The famous Fiji Mermaid should not be treated as a clean case of one known animal sewn to another. It belonged to a broader world of manufactured curiosities, where the whole point was to make the viewer lean closer and wonder where the animal ended and the trick began.
Barnum himself described the specimen as "an ugly, dried-up, black-looking, diminutive specimen, about 3 feet long. Its mouth was open, its tail turned over, and its arms thrown up, giving it the appearance of having died in great agony."
Not exactly the siren of sailor mythology.
Similar “monkey-fish” figures were associated with Japanese curiosity-making and nineteenth-century collecting, though the exact origin and construction of Barnum’s famous specimen remain difficult to prove. Some objects were treated as exotic marvels, some as religious or folk curiosities, and others as outright sideshow gaffs. The craftsmanship was grim and deliberate. These weren't accidents. They were made to disturb.
Origins: How the Feejee Mermaid Came to America
According to the commonly repeated chain of ownership, the specimen that became famous in America was purchased by Captain Samuel Barrett Edes in the early nineteenth century and exhibited in London around 1822. After that, it reportedly passed through several collectors' hands before landing with Moses Kimball of the Boston Museum.
Kimball knew exactly what he had, or at least knew enough to understand its commercial value. He later described the mermaid as a fraud, but he also recognized a profit opportunity when he saw one. He brought it to his friend P.T. Barnum in 1842. What happened next was less about the object and more about the man holding it.
How P.T. Barnum Turned a Taxidermy Prank into a Sensation
Barnum didn't just display the mermaid. He constructed an entire publicity machine around it. He planted or arranged newspaper letters under different names, each one claiming to have heard about a remarkable specimen. He circulated promotional material. He used a supposed naturalist, “Dr. J. Griffin” of the fictional British Lyceum of Natural History, to give the exhibit a scientific costume before the doors opened.
Dr. Griffin was not a real visiting naturalist. He was part of the act. The point was not simply to make people believe in mermaids. The point was to create just enough authority, mystery, and argument that people wanted to inspect the thing for themselves.
Barnum later wrote about the core challenge in his memoir Struggles and Triumphs: the goal wasn't to make people believe mermaids were real, but to make them curious enough to pay and judge for themselves. The exhibit drew massive crowds. Science dismissed it. The press ridiculed it. None of that stopped people from showing up.
Controversy, it turns out, is just advertising with better reach.
What Did the Fiji Mermaid Actually Look Like?
Visitors expecting a beautiful sea siren got something considerably worse. The figure was small, dark, leathery, and contorted, with a face frozen in apparent agony. Its mouth was open. Its teeth were visible. Its body looked less like a fairy-tale mermaid and more like a preserved warning from somewhere it should not have survived.
That grotesque quality was precisely what made it compelling. Audiences couldn't decide if they were looking at a fraud, a natural oddity, or something that genuinely shouldn't exist. The uncertainty was the attraction. The horror was the point.
What Happened to the Original Fiji Mermaid?
This is where the story gets murky and stays that way.
The original specimen’s fate is uncertain. One common account says it was lost when Barnum’s American Museum burned in 1865, but surviving documentation is muddy, and later gaff mermaids complicate the trail. Barnum’s museum also suffered another major fire in 1868 after rebuilding, which makes the object’s final path even harder to verify.
Harvard’s Peabody Museum of Archaeology and Ethnology holds a Feejee Mermaid specimen donated by Kimball’s heirs in 1897. That does not mean it can safely be called Barnum’s original. Harvard describes the object’s origins as unknown, and the Peabody specimen is better understood as one of several Feejee Mermaid-style figures associated with the same general tradition.
What definitely survived was the idea. Replicas, variants, and related gaff mermaids continued to appear in museums, sideshows, and oddity collections long after Barnum’s exhibit. The lineage of fakes outlasted the original object, whichever object that actually was.
Why the Hoax Still Matters
The Fiji Mermaid became cultural shorthand for a specific kind of deception: not one that hides from scrutiny, but one that thrives on it. Barnum understood something counterintuitive. The more people argued about whether the mermaid was fake, the more valuable the exhibit became.
For cryptid and sideshow history, the Feejee Mermaid remains one of the clearest examples of a gaff: a deliberately manufactured specimen designed to look like evidence of an impossible creature. It established a template for sideshow deception that shaped American carnival culture and still echoes whenever someone claims to have physical proof of a creature that should not exist.

Frequently Asked Questions
Was the Fiji Mermaid real?
No. The Fiji Mermaid was a constructed fake, not a real mermaid. It is usually described as a gaff specimen combining monkey-like and fish-like parts, though surviving Feejee Mermaid-style objects can also include papier-mâché, clay, fabric, teeth, claws, and other crafted materials.
Where is the Fiji Mermaid now?
The fate of Barnum’s original specimen is uncertain. One common account says it was lost in the 1865 fire at Barnum’s American Museum. Harvard’s Peabody Museum holds a Feejee Mermaid donated by Kimball’s heirs in 1897, but its exact origin is unknown and it cannot safely be identified as Barnum’s original.
Who made the Fiji Mermaid?
The maker of Barnum’s famous Fiji Mermaid is not known for certain. Similar “monkey-fish” and merman figures were associated with Japanese curiosity-making and nineteenth-century collecting, but the exact origin and construction of the famous exhibit specimen remain difficult to prove.
What is a Feejee Mermaid?
"Feejee" is an older spelling associated with Fiji. Barnum used the exotic-sounding name to give the exhibit a faraway origin story. "Feejee Mermaid," "Fiji Mermaid," and "FeJee Mermaid" all refer to the same famous hoax and the broader category of gaff mermaids it inspired.
Was P.T. Barnum the first to exhibit a Fiji Mermaid?
No. The specimen was reportedly exhibited before Barnum became involved, but Barnum was by far its most famous promoter. His publicity campaign, fictional expert, planted newspaper interest, and manufactured controversy turned a strange object into a national sensation.
The Lasting Legacy
The Fiji Mermaid never proved mermaids were real. What it proved was that a fake object can still become a real cultural artifact. Barnum’s exhibit survived in public memory because it gave people a reason to look twice: part fraud, part horror show, part media experiment.
The hoax also feels strangely modern. Give people something they can't quite explain, surround it with confident claims and public argument, and curiosity starts doing the work. The formula has not disappeared. Only the medium has changed.
The seams were always showing. That was never the point.
