Abstract

The short-beaked common dolphin, Delphinus delphis (Linnaeus, 1758), is a pelagic small cetacean distributed in tropical and subtropical waters. Here we present a new record for short-beaked common dolphins in Bahía Camarones, Patagonia, Argentina. The small group of dolphins was formed by three adult individuals and a smaller one, probably a juvenile. This sighting event is the southernmost record for the species in the Argentine coast, showing the importance of systematic surveys as an integral part of any program aimed at monitoring the well-being of local cetacean communities.
