A survey and distribution for Teredinidae (Mollusca - Bivalvia) at mangrove regions In Praia Dura, Ubatuba, São Paulo, Brazil

Abstract

A survey for bivalves (Teredinidae) at several sites in the Escuro River and Comprido River at mangrove regions in Praia Dura , Ubatuba, SP was conducted. Nausitora fusticula was the most abundant species found in all collection sites at the border of Comprido River meaning that the species was well adapted to the intertidal regions and to the large variation in salinity (0 to 33 S). N. fusticula was found with Bankiafimbriatula, Bankiagouldi and Bankia rochi at the mangrove region in contact with the water. At the regions less influenced by the tides N. fusticula occurred with Neoteredo reynei and few specimens of the genus Banida already cited. The species of Teredinidae was found at the maximum limit of penetration of the sea water during the high tides. When the salinity was lower neither Banida species nor Neoteredo reynei occurred, but Psiloteredo healdi and AC fusticula were found.
