- Аннотация: Heterochronic development has been proposed to have played an important role in the evolutionof echinoderms. In the class Ophiuroidea, paedomorphosis (retention of juvenilecharacters into adulthood) has been documented in the families Ophiuridae and Ophiolepididaebut not been investigated on a broader taxonomic scale. Historical errors, confusingjuvenile stages with paedomorphic species, show the difficulties in correctly identifying theeffects of heterochrony on development and evolution. This study presents a detailed analysisof 40 species with morphologies showing various degrees of juvenile appearance inlate ontogeny. They are compared to a range of early ontogenetic stages from paedomorphicand non-paedomorphic species. Both quantitative and qualitative measurements aretaken and analysed. The results suggest that strongly paedomorphic species are usuallylarger than other species at comparable developmental stage. The findings support recentnotions of polyphyletic origin of the families Ophiuridae and Ophiolepididae. The importanceof paedomorphosis and its correct recognition for the practice of taxonomy and phylogenyare emphasized
