Giovanni Bearzi al Malnisio Science Festival 2018


Delfini e balene: da mostri malvagi a individui senzienti


Attraverso immagini di grande impatto visivo, illustrerò gli stupefacenti cambiamenti che hanno trasformato il nostro modo di percepire i cetacei: per secoli, esseri mostruosi e maligni, animali nocivi da sterminare, prede; oggi, giganti gentili, simpatici cugini acquatici dalle mirabili capacità intellettive, individui senzienti.

L’evolversi di questa “biofilia marina” sarà in grado di rallentare il degrado ambientale e la perdita di biodiversità? Di certo alcune popolazioni di cetacei sono state decimate e versano in grave pericolo, anche nei nostri mari. È possibile evitarne la scomparsa?

Mnemiopsis leidyi in the Adriatic



During the summer we observed masses of this beautiful ctenophore, the comb jelly Mnemiopsis leidyi. It is an alien species in the Adriatic, and one with a high destructive potential as it feeds on fish eggs and larvae, as well as on zooplankton. The comb jelly bloom has the potential to further compromise Adriatic fish stocks that have already been compromised by decades of overfishing.

Marked flukes



The nicks in the flukes of this bottlenose dolphin likely originate from a bite given by some other dolphin.

Who's stronger?

Pelagic stingray feeding on floating seagrass



This young pelagic stingray Pteroplatytrygon violacea was observed feeding (with its belly up) on floating leaves of the seagrass Zostera marina.

In the Adriatic Sea waters off Veneto encounters with juvenile pelagic stingrays swimming near the surface are not rare. However, it is the first time we observed this somewhat unexpected foraging behaviour

Memories



The small house in Veli Losinj, Croatia, where Giovanni used to live in the 1990s while running the Adriatic Dolphin Project. Renovated by the new owners and repainted in light blue, it is as lovely today as it used to be back then. We returned after twenty years, as tourists.

Dead sea turtle



An adult male loggerhead sea turtle Caretta caretta, found floating adrift in open waters off the Po river delta. Fortunately we also see many sea turtles alive and well, including several juveniles.
