Professor Richard Fortey joins Dr Mark Griffa to look more closely at the behaviour of the Hermit Crab as they put discarded shells to good use as a means of protection. They investigate their ability to change shell to allow them to stay camouflaged in their surroundings, ultimately increasing their chance of survival. The body and claws of the Hermit crab have become adapted to allow them to recycle another creature's shell. They have become asymmetrical allowing the crab to close over the shell to protect it from predators.
