Hermit crabs are decapod crustaceans of the superfamily Paguroidea. They are not closely related to true crabs.
Most frequently hermit crabs use the shells of sea snails; the tip of the hermit crab's abdomen is adapted to clasp strongly onto the columella of the snail shell. As the hermit crab grows in size, it has to find a larger shell and abandon the previous one.
This habit of living in a second hand shell gives rise to the popular name "hermit crab", by analogy to a hermit who lives alone.
