In this note we contribute new evidence of epimeletic behaviour in Steno bredanensis in Brazilian waters. On 2 April 2007 we received information from lifeguards about a dead stranded rough-toothed dolphin at Prainha, Arraial do Cabo, east coast of Rio de Janeiro State, Brazil. The dolphin was a male juvenile, 187 cm in total body length from the tip of the upper jaw to the caudal notch, and it was in a moderate state of decomposition. The results presented here, in addition to previous studies, indicate that rough-toothed dolphins display a highly complex social structure.
