Cover illustration. The axial complex of echinoderms is morphologically and functionally associated with the gonads and genital haemal ring, with the perihaemal coeloms and the oral haemal ring, with the intestinal vessels, with the perioral coelom, and with the nerve structures associated with the perihaemal coeloms and epineural canals. However, the axial complex of Crinoidea differs so dramatically from that of other echinoderms that the homology has been questioned. In this issue of the Journal of Morphology, Ezhova and Malakov (pp. 1456–1475) present a detailed microscopic anatomical analysis of the axial organ complex of crinoids and compare it with that of all other clades of echinoderms. The cover image shows a graphical reconstruction of the morphology of the axial organ of Himerometra robustipinna , perivisceral coeloms, intestine, and gonads (see Figure 1a of that paper for details).
