The aim of this study was to estimate the fecundity of Dilocarcinus pagei Stimpson, 1861 and Sylviocarcinus australis Magalhães & Turkay, 1996, collected in the Paraguay River, Porto Murtinho County, State of Mato Grosso do Sul, Brazil, between coordinates 21º42,000'S 57º33,649'W and 21º41,449'S 57º33,770'W, in the period of April 1999 to March 2000. After general collection procedures, the specimens were measured and processed in laboratory conditions. The river water crab species hatch like juveniles and, frequently, female specimens were observed carrying eggs in different stages of development, besides juveniles and eggs at the same time. It was apparent in the frequency distributions that D. pagei has a carapace width average greater than S.... |

The present work is the first report of Dardanus venosus (H. Milne Edwards, 1848) in São Paulo State and extends the range of this species in the western Atlantic farther to the south in the Brazilian region. A total of twenty two males (mean shield length: 7.56 ± 1.62 mm, 4.7 to 10.9 mm), and fifteen females (7.25 ± 2.53 mm, 4.3 to 14.5 mm) were collected in 1987, 1998, 1999 and 2000 by scuba diving from three areas of Anchieta Island (23º33'S, 45º05'W) in the Ubatuba region, and south of São Sebastião Island (23º57.8'S, 45º16'W), northern coast of São Paulo State. No ovigerous females were captured during the study period. Shells of eleven gastropod species were occupied by D. venosus: Astraea latispina (Philippi, 1844), A. olfersii (Philippi, 1846), A.... |

The Hepatus pudibundus (Herbst, 1785) juvenile development was studied in laboratory, under the morphological and systematical stand points. The eight early juvenile stages were obtained from larvae hatched from eggs of two ovigerous females, collected at the northern coast of the State of São Paulo, Brazil. The experiments were carried out in a climatically controlled room at 25 ± 1°C, and steady saltness of 34. The youngs were maintened individually and food consisted of Artemia sp. nauplii and fragments of fish muscle.The first juvenile stage were particulary drawn and described. For the remaining juvenile stages the most representative frameworks were picked out, which allowed the characterization of the first eight stages. According to juvenile... |
