with some variation, the dolphins in rio de janeiro are of a single specie, the typical short-beaked mammal called delphinus delphis - they populate the waters spanning fro rio de janeiro to uruguay.

once in a while, even penguins make their way on rio's beaches, as they get caught in the wrong currents and lose their way.

welcomed with much cheering and attention by all cariocas, penguins do make headlines, get cared for, fed, and flown back to antarctica.
