Abstract

In this note we present new records of Pontoporia blainvillei stranded along the north-eastern coast of the Rio de Janeiro State from 1999 to 2007. Three dolphins were found in the known distribution of the isolated population on the northern coast of Rio de Janeiro and showed evidence of entanglement in fishing nets. Surprisingly, one dolphin (GEMM 140) was found in Rio das Ostras, only 6.5 km south of the previously known limit of the species' distribution. However, the stranding data presented here support the hypothesis of the discontinuous distribution of this species.
