Morphometric analysis of Littoraria angulifera em regioes estuarinas do Nordeste do Brasil
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 analys...

| description | 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 13[degrees]54'S and 15[degrees]44'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 |
