“…Palácio (1982) já enfatizava a importância da temperatura como fator limitante da distribuição de organismos marinhos e Fujita (1996), estudando a distribuição batimétrica dos ofiuróides, registra uma queda brusca da temperatura entre 100 e 400 m relacionando a isso as mudanças observadas na composição específica da fauna de Ophiuroidea do norte do Japão.…”

-This study focuses on the ophiuroids collected during the Programme of Evaluation of the Living Resources of the Exclusive Economic Zone for the Brazilian coast (REVIZEE), South Score/Benthos, in the states of Rio de Janeiro (Ilha Grande Bay), São Paulo, Paraná, Santa Catarina and Rio Grande do Sul (Tramandaí) (24° 07,113' S and 29° 48,500' S; and 43° 46,759' W and 49° 06,800' W). Samples were collected on the continental shelf and slope (60-810 m) using the following equipment: van Veen, box corer and a rectangular dredge. Individuals were identified, measured and photographed under a stereomicroscope and a scanning electron microscope. Growth series of the species that contributed with more than 10 individuals were analysed. A total of 5044 individuals were collected and were represented by 29 species, which belonged to seven families. The most abundant species were Ophiura ljungmani and Ophiomisidium pulchellum, which represented 79.7% of the total number of individuals. The analyses and description of species as well as the organization of the growth series allowed the verification that some characteristics of morphological structures used for the identification of the group remain unaltered throughout the life of the organism, whilst others undergo alterations. We recorded two new occurrences for the Brazilian coast: Ophiostriatus striatus and Amphilimna mirabilis. The ophiuroid fauna is composed of species with wide distribution along the Brazilian coast, such as Ophiothrix angulata and Amphipholis squamata, species with occurrence restricted to certain areas, such as Ophioleptoplax brasiliana and Nudamphiura carvalhoi. Most species were collected within the bathymetry limits previously described for them.Keywords -taxonomy; Ophiuroidea; geographical distribution; bathymetric distribution; Brazil.Resumo -Este estudo foca os ofiuróides coletados durante o Programa de Avaliação do Potencial Sustentável dos Recursos Vivos da Zona Econômica Exclusiva (REVIZEE), Score Sul/Bentos, nos estados de Rio de Janeiro (Baía de Ilha Grande), São Paulo, Paraná, Santa Catarina e Rio Grande do Sul (Tramandaí) (24° 07.113' S e 29° 48.500' S; e 43° 46.759' W e 49° 06.800' W). As amostras foram coletadas na plataforma e talude continental (60-810 m de profundidade) usando os seguintes equipamentos: van Veen, "box corer" e uma draga retangular. Os indivíduos foram identificados, medidos e fotografados em um estereomicroscópio e um microscópio eletrônico de varredura. Séries de crescimento das espécies com mais de 10 exemplares foram analisadas. Do total de 5044 indivíduos, foram identificadas e descritas 29 espécies pertencentes a sete famílias, sendo que as mais abundantes foram Ophiura ljungmani e Ophiomisidium pulchellum, representando 79,7 % do total amostrado. A análise e descrição das espécies assim como a organização das séries de crescimento, permitiram constatar que algumas estruturas morfológicas utilizadas para a identificação do grupo permanecem inalteradas durante toda vida do organismo, enquanto outras ...

“…According to Palácio (1982), this region comprises the internal or coastal portion of the São Paulo State Biogeographic Province, a zone of faunal transition characterized by complex seasonal environmental variations giving rise to an endemic fauna, adjacent to the provinces of the Caribbean and of Patagonian Provinces, and also including circumtropical organisms. According to Pires (1992), crustaceans dominated by crabs represent approximately 66 to 90% of the benthic fauna living in the inner continental shelf of the northern São Paulo State.…”

The objective of the present study is to characterize the physical and chemical environmental parameters of Ubatuba Bay (SP), as a subsidy for studies of the composition and distribution of benthic crustaceans which live on the non-consolidated sublittoral bottom of this area. Depth, temperature, salinity, dissolved oxygen, organic content and granulometric composition of the sediments were measured monthly from September/95 to August/96 in eight subareas of the bay. The bay presents an average depth of 9.3 m and is characterized by the following annual mean values for the hydrologic factors: temperature 23.8 o C, salinity 33.2‰ and dissolved oxygen 5.11 mg/l. The annual mean for the organic matter content of the bay bottom sediments was 11.8% and most subareas presented a grain size composition dominated by pelitic sediments. These peculiar abiotic characteristics are very important for the reproduction and development principally of brachyuran and anomuran crabs, and shrimps which have a close relationship with those substrates.Key words: Crustacea, environmental factors, sediment, organic content, Ubatuba, Brazil. RESUMO Caracterização dos parâmetros físicos e químicos da Enseada de Ubatuba, litoral norte de São Paulo, BrasilO presente trabalho objetivou a caracterização de alguns parâmetros físicos e químicos da Enseada de Ubatuba (SP), como subsídio para estudos sobre composição e distribuição de invertebrados bentônicos associados ao substrato não-consolidado desta área, além de servir para comparações com cenários futuros da região. Foram estabelecidas oito subáreas para a amostragem dos parâmetros ambientais (profundidade, temperatura, salinidade e teor de oxigênio dissolvido na água, teor de matéria orgânica e granulometria do sedimento de fundo). Em todas a subáreas as coletas foram efetuadas mensalmente, durante três dias consecutivos, de setembro de 1995 a agosto de 1996. As amostras de água foram coletadas com uma Garrafa de Nansen e o sedimento de fundo com um pegador do tipo Van Veen (1/40 m 2 ). Os valores médios dos parâmetros encontrados na Enseada foram: profundidade (9,3 ± 3,66 m), temperatura (23,8 ± 0,62 o C), teor de oxigênio dissolvido (5,11 ± 0,29 mg/l), salinidade (33,2 ± 0,35‰) e teor de matéria orgânica (11,8 ± 5,35%). Quanto à granulometria, houve predomínio das areia fina e muito fina. Entre as subáreas, pode-se constatar diferenças significativas na profundidade, no teor de oxigênio dissolvido, no teor de matéria orgânica e na granulometria do sedimento. Os valores encontrados permite-nos caracterizá-la como uma enseada com um padrão semelhante às adjacentes, mas com parâmetros hidrológicos e sedimentológicos fortemente estabe-
