When a hermit crab spots a new shell, it'll size up the shell for a good fit.

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.

Do hermit crabs fight over shells?

When hermit crabs fight, they're really squabbling over the shell that they can call their home. As crabs get bigger, they go in search of bigger shells, and the most convenient place to find a larger shell is on another crab.
