Hermit crabs can't be too picky about choosing a new home, because while they're looking for new digs they're at the mercy of predators.
But hermit crabs do seem to have a sense of style when it comes to choosing a new shell, and they're often attracted to shells that have shiny bling, sharp edges or shells that look tough and intimidating.
I can't imagine any animal, predator or otherwise, would want to mess with a hermit crab sporting a creepy doll head on their back, so this hermit crab shared on Reddit may have found the ultimate form of passive defense.
