Suitable shells for hermit crabs
It is known that the growth and egg production of marine and especially land hermit crab are affected by the weight of the shell occupied. (Bertness 1981b, Osorno et all. 1998)
Experiments have shown that hermit crabs in well-fitting shells can survive without food or water six times as long as those removed from their shells.
