| ABSTRACT A new species of orbiniid, Scoloplos maranhensis sp. nov., is described from a tropical mangrove (Quebra Pote, state of Maranhão, Brazil, 02°41.344’S; 44°12.604’W) along with a comparative table with all Scoloplos species. The main distinguishing characters of S. maranhensis sp. nov. are thorax with 12 chaetigers, neuropodia from first chaetiger, notopodia and neuropodia without papillae, conical branchiae from 12th chaetiger to the end of the body, being larger and more robust in the anterior segments. Thoracic notopodia with seven crenulated capillary chaetae and abdominal notopodia with furcated and capillary chaetae. Thoracic neuropodia rounded with two crenulated capillary chaetae and six slender-smooth hooks, abdominal neuropodia with a... |

| Seasonal variation of large medusae abundance and biomass was studied in the North Bay, Santa Catarina, southern Brazil (27°30'S, 48° 32'W), from February to December 2005. Collecting was conducted seasonally with the help of fishing bottom trawl in 30-minute sections (12 in summer, 18 in each of the remaining seasons) in six stations, totaling 66 samples. Eight species were found: the hydrozoans Aequorea sp., Olindias sambaquiensis Müller, 1861, and Rhacostoma atlantica L. Agassiz, 1850; the cubozoans Chiropsalmus quadrumanus (Müller, 1859) and Tamoya haplonema Müller, 1859, and the scyphozoans Aurelia sp., Chrysaora lactea Eschscholtz, 1829 and Lychnorhiza lucerna Haeckel, 1880. Capture rates were low, up to 38 indiv. ha-1, and only ~47% of the samples... |

| Olindias sambaquiensis Muller, 1861 (Olindiidae) é uma hidromedusa comum e abundante no litoral Sul do Brasil. Em contribuição ao estudo da espécie, variações morfológicas foram analisadas em 1092 exemplares coletados em águas costeiras de Guaratuba, Paraná. Em 70 (6,4%) indivíduos, foram reconhecidas alterações relacionadas ao número, forma e ramificações dos canais radiais e centrípetos, que resultaram, em diversos casos, em uma aparente mudança do padrão de simetria da espécie. |

| Associations between jellyfish and other organisms are frequently reported. Neverhteless, few of those records include crabs inhabiting medusae. Lychnorhiza lucerna Haeckel, 1888 were sampled (n = 1988) on the coast of the State of Paraná (25º20'-25º55'S, 48º10'-48º35'W), southern Brazil, from December 1997 to December 2004. Eight percent (166 individuals) of the medusae had one spider crab Libinia ferreirae Brito Capello, 1871 living within its subgenital porticus or on the oral arms. Megalopal stages of the same crab were also found on three jellyfish. All crabs associated with L. lucerna were young and smaller (< 3 cm) than solitary crabs caught on the bottom. Thus, L. ferreirae probably colonizes the jellyfish as a late larva and uses it as a... |

| The scyphozoan Phyllorhiza punctata von Lendenfeld, 1884 (Mastigiidae), known only from Indo-Pacific waters prior to the 1950s, is today found far from its original distribution, probably due to human activities. First seen in 1955 in Brazilian waters, medusae were found in southern and southeastern coasts, disappearing (at least as a medusa) in the early 1960's. Another population was found in the late 1990's, in the state of Bahia, and again in late 2001, many sightings were reported along the coasts of Paraná and Santa Catarina (25º20'S, 48º12'W to 27º26'S, 48º22'W). A large summer bloom, followed by decline and disappearance in winter and spring, occurs every year since then. The reasons for this recent mass occurrence are unknown. Despite few... |
