Though they may look tough on the outside, the land hermit crab is a true softie on the inside. For these invertebrates, finding the perfect shell is critical to their survival because, beneath it, they have a long abdomen and a soft exoskeleton that allows them to fit into the unique spiral shape of a shell.
