A recent reassessment of the world-wide taxonomy of Tursiops confirmed the validity of the subspecies Lahille?s bottlenose dolphin (Tursiops truncatus gephyreus; Lahille 1908). These dolphins are distributed in the coastal waters of the southwest Atlantic Ocean, between the state of Parana (southern Brazil) and the province of Chubut (Argentina). They occur in two genetically and geographically isolated ?subpopulations? under the IUCN definition: one ranging along the coast of southern Brazil and Uruguay, composed by at least five management units and operating as a metapopulation, and a second ranging along the coast of Argentina.
