RESUMO

Anomalocardia brasiliana (Gmelin, 1791) (Bivalvia, Veneridae) is a mollusk with great distribution along brazilian shores. It habitats from estuaries until shores, living burrowed in the sand. This diversity of habitats may appear somehow in the phenotypic traits. The main objective of this dissertation was to understand how morphological characteristics of shell vary among specific environment conditions. Populations from Cananéia, São Sebastião, Ubatuba (São Paulo) and Saquarema (Rio de Janeiro) were sampled to this study. Environmental differences were tested using single measures, pair-to-pair relations between measures and comparing the whole group of measures. Significant statistical differences were obtained between single measures but no relations due environmental differences were found. The pair-to-pair tests vary. Some of them could be related to environmental differences but others could not. The whole group of measures tests showed differences among environmental conditions as well as localities. Relative age differences among populations could interfere in the tests above described
