Feeding: It is a fish mostly “teutofago” (it eats squids above all). Only the adult males possess two big teeth situated at apex of the jaw. Social behaviour: Generally observed isolated or in small groups (composed by 3-4 individuals), whose social structure is not known. Vital cycle: Information in merit are rather insufficient; it seems however that the sexual maturity is reached when the length of the body exceeds five meters. Recognition in sea: The position of the dorsal fin and the coloration are useful characters which helps the identification. It is a category whose sight frequency usually low; however, in the summer 1898, a discreet number of observations have been carried out which encourage a widening of the scientific search on its Biology in the waters of Liguria Sea.
