Hermit crabs have a soft tail end and live inside empty sea snail shells for protection. As they grow they need to find a bigger snail shell to move into. They thoroughly check any empty shells before moving in, but some crabs may fight over a ‘desirable residence’. Hermit crabs on the rocky shore hide in their shells to avoid drying out at low tide. They use their largest claw to seal the entrance.
