Periclimenes dardanicola chiefly white, with red along the edges of the carapace and the abdominal somites. The legs are transparent yellow, with red bands. "P. dardanicola" is associated with the sea anemone "Calliactis", which is carried by hermit crabs of the genus "Dardanus", including "Dardanus arrosor", "D. crassimanus", "D. lagopodes" and "D. pedunculatus". This is one of the few examples of ecological associations between two species of decapod crustaceans. Specimens of "Periclimenes dardanicola" have been collected from various locations in the western Pacific Ocean, namely Suruga Bay (Japan), Vietnam, and Borneo (Indonesia). Although only formally described in 2006, this species has been
