Hermit Crab (Dardanus calidus), Port-Cros NP, France Dardanus calidus can grow to a length of 12 cm. It uses large gastropod shells which it often decorates with one or more sea anemones of the species Calliactis parasitica. The relationship with the anemone is truly symbiotic, since the anemone gains scraps of food from the hermit crab, while the crab benefits from the anemone's stinging tentacles deterring predators.
