How does a hermit crab protect themselves?

Why is my hermit crab out of its shell and not moving?
When a hermit crab is out of its shell—either because of a molt or another environmental cause—it’s stressed and vulnerable. Your crab needs protection from the other crabs in the habitat, as well as a little coaxing so that it will return to its shell. The molting cycle can take up to one month, so be patient.
Do hermit crabs come out of their shell to die?
Eventually, your hermit crab won’t be molting, hiding or cooling off — he will die at some point. If he’s dead, his body will droop out of its shell, but this is also common in molting crabs. If you come across a “body” in the crabitat, don’t assume it’s your dead crab because it may be your crab’s exoskeleton.
What happens if you disturb a molting hermit crab?
