Anemone Hermit Crab

The hermit crabs of this family have formed a symbiotic relationship (mutualism) with the anemone Calliactis polypus. The anemone attached to the shell provides camouflage and protection while the anemone benefit by getting food from the crab. By moving around the reef, the Anemone hermit crab also help the anemones disperse. When the crab find a new shell, it transfers the anemones to his new home.
