According to the National Oceanic and Atmospheric Administration, no verifiable evidence of the existence of aquatic humanoids, or mermaids, has ever been discovered. Animal Planet's Mermaids: The Body Found Documentary disputes this claim. The documentary details the story of two scientists who claim to have acquired a mermaid's physical remains.
The documentary explores the legend of mermaids and shows carved depictions and illustrations. It examines why mermaids could exist under the aquatic ape theory, but does not offer verifiable evidence. Over the last decade, photographs of the Chennai Mermaid, the Tsunami Mermaid and the Marina Wash Up Mermaid have been published, but remained unverifiable.
