What is a hairy crab called?

There isn't one specific name for a "hairy crab." The term "hairy crab" is a general description that could refer to several different crab species, many of which have their own unique names.

Here are a few examples of crabs that could be considered "hairy":

* Hairy Stone Crab: This is a common name for *Lithodes aequispinus*, a species found in the North Pacific Ocean.

* Japanese Spider Crab: This crab, *Macrocheira kaempferi*, is famous for its long, spidery legs that are covered in hairs.

* Hairy Shore Crab: This is a general term for several species of crabs that live in the intertidal zone, including the *Pachygrapsus crassipes* and the *Hemigrapsus oregonensis*, both of which have hairs on their bodies and legs.

To give you a more specific answer, you'd need to tell me more about the crab you're thinking of. Where did you see it? What did it look like? What features were particularly "hairy"?
