ABSTRACT
One of the most enigmatic features of the echinoderms is the tremendous difference in the morphology of adults and their larvae. Even after 150 years of the study of echinoderms there are still well-known larvae of ophiuroids that have not been assigned to adults. Most common amongst these are Ophiopluteus compressus and Ophiopluteus bimaculatus. By a process of deduction and reduction we suggest species that we believe are the adults of these ophioplutei. In the poster in Dijon we presented evidence for the distribution of these two ophioplutei and compare these data with the benthic distribution of potential adults. Our evidence is also supported by observations and growth stages of post larvae from these ophioplutei that have been collected in the field or cultured in the laboratory.
