What is the term describing the Norwegian Lundehund's characteristic of having extra toes?

Answer

Polydactyly

Polydactyly is the specific term used to describe the physical trait exhibited by the Norwegian Lundehund wherein it possesses more than the standard number of digits. In this breed, this manifests as six fully developed toes on each foot, complete with functional muscle and skin. This feature is highly valued as it directly contributes to the breed's ability to maintain exceptional purchase and stability while navigating the slippery, uneven surfaces encountered during its historical work on coastal cliffs.
