Have you heard of a flatypus? How about a platysausage or a fattypus? These are all terms coined by Jack Ashby to describe badly-stuffed taxidermy platypuses.
"I think they're the most amazing animals that ever evolved, and they are very popular in museums," he said.
Dr Ashby, a Museum of Zoology assistant director at Cambridge University, says he has seen a lot of dodgy taxidermy in museums around the world during the course of his work.
