Distribution of Risso's dolphin (Grampus griseus, Cuvier 1812) in Chilean waters
Here we review the knowledge of Risso's dolphin Grampus griseus in Chilean waters. Based on analysis of 44 records, this species appears to have a continuous distribution along the Chilean coast between 20º13'S and 40ºS and we suggest that the reported southernmost record from Chile (~52°S...

| Résumé: | Here we review the knowledge of Risso's dolphin Grampus griseus in Chilean waters. Based on analysis of 44 records, this species appears to have a continuous distribution along the Chilean coast between 20º13'S and 40ºS and we suggest that the reported southernmost record from Chile (~52°S) could be Atlantic Risso's dolphins. The Chilean records show a peak during the austral summer and indicate a preference for waters over 1000 m in depth. Mass stranding, interaction with fisheries, and associations with other cetaceans species are also reviewed. |
