On the occurrence of scyphozoan ephyrae (Cnidaria, Scyphozoa, Semaeostomeae and Rhizostomeae) in the southeastern Brazilian coast

Abstract: The occurrence of ephyrae of the scyphozoan orders Semaeostomeae and Rhizostomeae is reported for the first time for the Brazilian coast. The specimens, caught in plankton tows in the São Sebastião Channel and the Cananéia lagoon estuarine system, are: Chrysaora lactea (Semaeostomeae), Phyllorhiza punctata (Rhizostomeae), and an unidentified species of Pelagia (Semaeostomeae). A table with all species of scyphozoan with the known life cycle is provided.

“…Although we did not find A. aurita ephyrae in our samples, recently released ephyrae of this species were reported by Mianzan (1989a) who suggested the use of this coastal area as a reproduction site. Regarding C. lactea even though medusae are rather common and widespread, ephyrae have been rarely observed in plankton samples elsewhere (Mianzan 1989a(Mianzan , 1989bTronolone et al 2002). In our samples, however, ephyrae of C. lactea were frequently found, which supports the suggestion by Mianzan (1989a) about the reproduction area for these scyphozoans.…”

“…The very small medusae obtained in early summer also point to the presence of scyphistomae populations in Paraná and Santa Catarina regions, with the whole life cycle of the species occurring in the area. In April 2001, and in January and February 2002, ephyrae have also been collected in Cananéia, São Paulo (TRONOLONE et al 2002). Smaller individuals caught in late May probably were senescent.…”
