| Shell selection by the hermit crab Paguristes tortugae Schmitt, 1933 from Anchieta Island (Brazil) was analyzed using the six most frequently occupied shell species in the field and taking into account the sexual condition of the individuals, the shell size and the shell species. The experiments were conducted under laboratory conditions and the shell species preference was estimated on the basis of the frequency that each species was chosen by the individuals. The preferred shell species and size were determined by regression analysis. The highest correlation coefficients were obtained for the relations between the hermit dimensions and shell dry weight. The ovigerous females preferred shells with larger internal volume: Leucozonia nassa (Gmelin, 1791)... |

| This work characterizes the composition of Brachyura from Schizoporella unicornis. The samples were collected in 1995 at Itaguá Beach, Ubatuba (SP), at three month intervals, during all seasons from January to December. The Bryozoa colonies were obtained by snorkeling at a depth of five meters in daylight. A total of 323 specimens were collected from four families (Xanthidae, Portunidae, Majidae and Grapsidae). Pachygrapsus transversus, Hexapanopeus schimitti, and Menippe nodifrons occurred in all seasons. The highest and lowest number of individuals occurred during the spring and autumn, respectively. Xanthidae exhibited the highest density during the summer, autumn, and spring, while Grapsidae exhibited the highest density in winter. It was noted the... |
