The work of the Cenpat done on the Commerson´s Dolphin
(Cephalorhynchus commersonii would be carried out by two investigators - Susana Pedraza and Javier Klaish –
under supervision of Enrique Crespo. They both speak English and Spanish. The organization of the expedition would be carried out by the collaboration between the investigators and
Doradillo Velas.

Patagonia. He is the leading investigator of the Cenpat and coordinator of America del Sur for the Cetacean Specialist Group. Nowadays, Enrique Crespo is directing two
studieson the Commerson´s Dolphin (Cephalorhynchus commersonii) the studies are the following:
