Resumo: | Abstract The gastropod Littoraria angulifera (Littorinidae) is an exclusively estuarine mollusk with Neotropical anfiatlantic distribution. Recent studies indicate a possible use of the species as bioindicator. The aim of this study was to analyze the shell height, as well as to perform a morphometric analysis of the reproductive apparatus of L. angulifera collected in 22 sampling points located between latitudes 13º54'S and 15º44'S in the South Atlantic, State of Bahia, Northeastern Brazil. The specimens were obtained in different estuarine environments including mangroves, as well as on rocks and concrete walls in places close to ports, shipyards and berths during January and February 2014. All specimens (n = 880) were analyzed regarding the sex and shell height/morphology, 440 were analyzed about the reproductive apparatus morphometry and 15 in histological description. The average shell height of animals from artificial substrates in nautical areas was lower (p<0.05) than the animals from mangroves, mainly in preserved areas, evidencing relation with human impacts and desiccation. The morphometric analysis of L. angulifera reproductive tract allowed us to conclude that the length of prostate in males and of palial oviduct in females may be useful in the reproductive evaluation of the species. |
