Abstract
Realizou-se o levantamento e estudou-se a distribuição das espécies de Teredinidae no manguezal da Praia Dura, Ubatuba, São Paulo, Brasil. Investigou-se a abundância das espécies nas regiões mais em contato freqüente com a água e as menos atingidas pelas preamares. Determinou-se, também, a distribuição das espécies ao longo do Rio Escuro, segundo um gradiente decrescente de salinidade: Nausitora fusticula foi a espécie mais abundante ao longo do Rio Comprido, demonstrando que esta espécie está bem adaptada a região entremarés e a grande variação de salinidade (0 a 33 S). Na área do bosque em maior contato com a água N fusticula é encontrada com Bankiafimbriatula, B. gouldi e B. rochi e, nas áreas menos atingidas pelas preamares, divide o ambiente com Neoteredo reynei, ocorrendo poucos indivíduos das espécies de Banida já mencionadas. O limite máximo da ocorrência de Teredinidae no Rio Comprido, correspondeu ao limite máximo da penetração da água do mar durante as preamares. Nas áreas menos salinas do rio, praticamente deixam de ocorrer todas as espécies de Banida e Neoteredo reynei, começando a surgir Psiloteredo healdi, com quem N. fusticula passa a dividir o ambiente, sendo posteriormente dominada por aquela.
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.
