Superworms Clean Animal Skeletons in Iran Museum

Researchers in Iran used superworms, beetle larvae sold as pet food, to efficiently and safely clean animal skeletons at a natural history museum in Mashhad. The team at Ferdowsi University faced a shortage of freezer space for incoming animal specimens and sought alternatives to traditional cleaning methods like chemical treatments or boiling, which can damage bones or harm the environment.

Superworms proved to be “super gentle” and capable of cleaning skeletons of various sizes, from mice to wolves, without causing damage. The researchers found that 10 to 15 larvae work best for each specimen, and the same larvae can be reused for up to six months.

While some experts note potential risks like accidental bone breakage or the worms’ preference for a vegetarian diet, the method offers a potentially accessible solution for institutions lacking advanced facilities. Researchers hope superworms will become a viable option for preparing specimens for study and exhibition.
