If you are asking if they defecate (poop) then yes, they do. The orifice where the waste comes out is on the abdomen, which stays within the hermit crab's shell. The crab will defecate in it's shell, and it's feces look like little brown turds. If you have ever seen a gold fish go to the bathroom, it looks a bit like that, except brown and dry and in short little bits.
The crab will occasionally clean the feces out of his shell using his small back legs which are the same ones that hold him in his shell. They are attached to the abdomen (the white part) and are very short.
