Feeding: Its diet is substantially constituted by “cephalopods” (several species of squids); the fact is confirmed also by the reduced set of teeth, typical of the “odontoceti teutofagi”. Social behaviour: It is met in small groups constituted by ten individuals, which sometimes can meet to form consisting branches. The study of the socio-biology of the Grampo, to date not very famous, enters currently in a plan of search lead in Liguria Sea from the Tethys Research Institute. Vital cycle: The relative data of vital cycle of the Grampo are currently much insufficient and fragmentary, however in progress to be they deepened. Identification in sea: It can easily be distinguished from other species for the characteristic dorsal fin and the unmistakable coloration. Disseminated in all the Mediterranean Sea, it is more abundant in the western river basin, where it is possible watch it on the bathymetrics between 600 and 1000 meters.
