Feeding: Common finners seen in Liguria Sea eat during summer eat exclusively “Norvegica Meganyctiphanes” that they swallow in great amounts expanding their throat furrows.
Social behaviour: The common finner is watched in small groups composed by two to three exemplars, or isolated. The real consistency of relationship between the various exemplars is not known; the only sure and long-lasting relation is the one between the mother and its small baby.
Vital cycle: Genetically distinguished from the species of the Atlantic Ocean, it is almost sure they reproduce themselves in the Mediterranean Sea. Gestation last 11-12 months, the sexual maturity appears between the 8 and 12 years of age. Among the most long-lived cetaceum it is one of the species, being able to reach 90 years.
Identification in sea: Recognisable from dimensions and for the characteristic vertical breath upside down cone shaped, 6 meters high. Another sign, which differentiates it from all the other finners is the coloration of the skilful mid jaw. The clearer shape of the dorsal fin and shadings on the skilful side of the body are typical and unique signs of Identification. These characteristics highlight in a plan of search of the Tethys Research Institute in Liguria Sea, have allowed to catalogue more than 350 common finners that which have been watched and recognised in successive years. The only “Misticete” in the Mediterranean Sea, its population in the western river basin is estimated in more than 3,000 exemplary. After the Streaked Stenella it is the more watched cetaceum.
