The main characters that permit identification of the subsequent juvenile stages were assessed, as well as the moult interval and increment during successive moults and the beginning of development of the secondary sexual features. Megalopae of A. rubripes were collected from the Ubatuba region, São Paulo, Brazil using plankton and neuston nets. Morphological changes in body parts have been recorded for each stage and sex, as well as the duration of the intermoult period was noted. Possible effects of laboratory holding time on growth were checked by means of analysis of covariance. The importance of standardization of the terminology of setae is emphasized.53-64engLarval stageMorphological descriptionNeustonSexual differentiationArtigo10.1080/07924259.2010.548645WOS:000289010300007Acesso restrito579647401229365444759602002565920000-0002-2067-5406
