| 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 photo-graphed 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... |

| This study describes the gametogenic cycle of Ophioderma januarii Lütken, 1856, a common species of ophiuroid in Southeastern Brazil. The specimens were collected during the project "Biodiversidade Bêntica Marinha no Estado de São Paulo-BIOTA/FAPESP-Bentos Marinho" (Marine benthic biodiversity in the State of São Paulo-BIOTA/ Fapesp-Marine Benthos) which was conducted off the northern coast of the state of São Paulo. Specimens were captured monthly between February 2001 and December 2002. Due to the low number of individuals the monthly data was grouped in seasons (spring to winter). A total of 101 specimens were obtained: 33 in spring, 10 in summer, 23 in autumn, and 35 in winter. The gonads of eighty-eight individuals (45 females, 42 males, and one... |

| Ophiomusium (Ophiolepididae) and Ophiomisidium (Ophiuridae) are similar, but differ in features such as size of the adult, number of disc dorsal plates, length of the arms, shape of the first ventral arm plates and number of the tentacle. In this contribution, a large number of specimens of Ophiomusium acuferum Lyman, 1869 and Ophiomisidium pulchellum (Wyville Thomson, 1878) were sampled from southeastern and southern Brazilian at depths ranging from 46 to 1300 m. A close analysis has shown that specimens identified as Ophiomisidium pulchellum (C.W. Thomson, 1877) in several Brazilian museums are actually Ophiomusium acuferum Lyman, 1875. A total of 2330 individuals were examined: 2046 specimens of Ophiomusium acuferum ('Evaluation of the sustainable... |

| Os ofiuróides aqui analisados são procedentes dos programas "Biodiversidade Bêntica Marinha no Estado de São Paulo" - BIOTA/FAPESP-Bentos Marinhos, "Avaliação do Potencial Sustentável dos Recursos Vivos da Zona Econômica Exclusiva" - REVIZEE/Score Sul-Bentos e "Utilização Racional dos Ecossistemas Costeiros da Região Tropical Brasileira: Estado de São Paulo" - INTEGRADO/Subprojeto Bentos. As amostras analisadas foram coletadas nas regiões da plataforma e talude continental do Sudeste e Sul brasileiros, em profundidades entre 10 e 800 m. São aqui descritas e ilustradas quatro espécies de Ophiuroidea, as quais representam novos registros de ocorrência para o Brasil, duas da família Ophiuridae, uma de Amphiuridae e uma de Ophiochitonidae. Este é também o... |
