If the Bermuda land crab, Gecarcinus lateralis, loses numerous walking legs or both chelipeds, it undergoes almost immediate preparations for molting with attendant limb regeneration. Injections of the arthropod-molting hormone, ecdysterone, have no effect in either intact animals or those missing legs.
