The presence of a characteristic crustacean larval type, the nauplius, in many crustacean taxa has often been considered one of the few uniting characters of the Crustacea. Within Malacostraca, the largest crustacean group, nauplii are only present in two taxa, Euphauciacea (krill) and Decapoda Dendrobranchiata. The presence of nauplii in these two taxa has traditionally been considered a retai...

To study the relationships among Sciaenidae fish and Penaeoidea shrimp biomass, fieldwork was carried out in the north coast of São Paulo state, Brazil, during the four seasons of 2001. Samples were collected in transects from different depths at Ubatuba, Caraguatatuba, and São Sebastião cities. Water and sediment were collected from each transect. The hypotheses that the environmental factors ...

• Pelagic larvae were retained in a zone of density front. Interannual variability the larval retention rates was low. Larval and front position correlated. Marine fronts are oceanographic drivers for marine species dispersal, especially their pelagic organisms like larvae. Larvae can aggregate at consequently have limited which turn reduces connectivity between populations. Due to high variati...
