Like snails, it is incredibly difficult to humanely get the shell off hermit crabs and ensure they'll still live. Also, because of the fact they have an exoskeleton (skeleton on the outside), injecting needles cannot get through to their innards. They hide when you touch them, plus they're quite small compared to most pets.
As most people know hermit crabs have gills most animals that breathe under water have gills for example a fish. The hermit crabs gill's can work on land but in order for the hermit crab to survive they hermit crabs gills have to be moist....
