The symbiotic relationship between hermit crabs and sea anemones is a well-known example of mutualism in the sea. Many species of hermit crabs carry symbiotic sea anemones on their chelipeds or the external surfaces of the shells they inhabit (Williams and MacDermott, 2004; Antoniadou et al., 2013).
Why do hermit crabs and snail shells live together?

Where do hermit crabs get their shells from?
The shells that hermit crabs seek are made by marine gastropods that secrete calcium carbonate from their mantel —the organ that covers their soft bodies. The shell is built up in deposits until the calcium carbonate becomes a crystalline structure held together via thin membranes of organic material.
