Within the Anomura, there are several families of hermit crabs, each with multiple species. For example, some common hermit crab families include:
* Paguridae: This is the largest family, with over 500 species.
* Diogenidae: This family includes the "true" hermit crabs.
* Coenobitidae: This family contains the terrestrial hermit crabs.
So, to specify the scientific name of a hermit crab, you need to know the genus and species. For example, the common hermit crab is scientifically named Pagurus bernhardus.
