| 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... |

| The ophiuroid Ophionereis reticulata (Say, 1825) occurs in the sediment-rocky shore interface, under small stones. Its diet is analyzed in this short communication. Specimens were collected at the Praia Grande beach, located on the northern coast of the state of São Paulo, Brazil, in July, 2002 and January, 2003. The animals were fixed in 70% ethanol and dissected to obtain their stomach contents. Of the total (35), 77.1% (27) had ingested some kind of food and, among those, 81.4% (22) had more than one item. The mean number of food items per stomach was 1.9. Ophionereis reticulata is an omnivorous species, consuming sediment, green and red algae, and polychaetes. |

| 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... |
