Decorating materials in Loxorhynchus crispatus are attached to the hooked setae of the dorsal surface of the exoskeleton. Examination with the scanning electron microscope reveals that the setae bear spinules, a median groove, and a spiralled region. Ablation of these setae prevents the crabs from decorating, but removal of the glands of the first maxillipeds has no effect on the process. Attachment of decorating material appears to be mechanical, not by means of an adhesive secreted by the mouthparts.
