Here is an uncommon video of a common blue-legged hermit crab in the act of changing shells.  Don’t blink … the swap transpires in about one second (a little after the 1:00 mark).  Hermit crabs do not build their own shells, so make sure to provide your hermit crabs additional shells for them to move into as they grow.
