University staff and students are doing tests to uncover the origins of a museum exhibit which looks like a mummified mermaid.
They have already found the mysterious Buxton Mermaid's hair is human.
The University of Lincoln team is now testing the DNA of the mermaid's tail to see what fish it came from.
Anita Hollinshead, a conservation and restoration masters student, came across the mermaid while working at the Buxton Museum and Art Gallery.
"We think that it came from the mid-19th Century," she said.
"We are still doings tests to find that out."
It will be interesting to see if this "mermaid" was exported from Japan. Mummified supernatural creatures, or "yokai", were popular attractions at traveling fairs long before regular contact with the west was established. Many ended up being given as temple offerings, and thanks to the protected environment of the shrines some have been able to survive for hundreds of years.
It's fascinating how both the east and west developed a tradition of faux creatures and body parts for both entertainment and religious reasons.
