Abstract

Despite the recent increase in research efforts regarding jellyfish and associated blooming events, which have important economic and health impacts, much of the evolutionary relationships among Medusozoa are still unclear. In this sense, much debate exists concerning the number of species within the genus Aurelia (moon jellyfish), dating back to the 1800s and still unresolved. Through time, many of the species described were synonymized and only A. aurita, A. limbata and A. labiata were considered valid, although recent molecular efforts have proposed additional four to six species. This emphasizes the crypticism of speciation within the genus, and therefore the need of more detailed morphological, genetic and geographical evaluation of presumed species. In this study, we propose to describe in detail the suggested molecular species of the Brazilian coast, Aurelia sp. In order to accomplish this we will analyse the morphology of living animals in different life cycle stages (polyps, ephyrae and young medusae) and of preserved specimens from museum collections, as well as genetic data from specimens of distinct localities along the coast. A discussion of the genus will also be necessary in order to characterize the identity of the species from the Brazilian coast. This will be an important step towards understanding speciation within the Medusozoan clade, and therefore better comprehending its biodiversity. (AU)
