Abstract
The bivalve Petricola typica occurs from North Carolina (USA) to Brazil where, according to Rios (1970), its range extends to Rio Grande do Sul. The species can be found in coral blocks of Mussismilia hispida, inside colonies of Schizoporella unicornis (a calcarean bryozoan) and, more frequently, inside the sandy reefs built by the polychaete Phragmatopoma lapidosa (intertidal zone). Initial settlement probably occurs in a pre-existing cavity, which is enlarged to form a hole into which the bivalve fits exactly when its valves open. The shell, mantle, and siphons are described in detail. Special attention was paid to the ctenidia, labial palps, and stomach.
