    Corallium species have ecological, cultural and commercial importance and thus require tools to assist with their identification for both management and trade. The organic matrix (OM) of the skeletons of four Corallium species (C. rubrum, C. konojoi, C. secundum and C. elatius) was examined to provide insight into the biomineralization process and to develop a new tool of identification. The pattern of OM and the set of soluble organic matrix proteins (SOM) in the skeletons were examined by gel electrophoresis. Staining of cross-sections of skeletons showed a common cyclic, concentric pattern of OM during growth. Differences in molecular weight and isoelectric point were observed for proteins in the SOM in different Corallium species but not among different populations of Corallium rubrum. Immunolabeling with antibodies against the SOM of C. rubrum showed labeling of the OM of the three other Corallium species suggesting the presence of common epitopes.
