Whales and dolphins in Pordenone, Italy
Giovanni's seminar in Pordenone, held yesterday, focused on shifting perceptions of whales and dolphins over time, and the reasons why it is worth studying and protecting these animals. Thank you Guido Perin (President of Nature Society 'Silvia Zenari', Pordenone) and Umberto Chalvien (Director of Museum of Natural Sciences, Pordenone) for organising the event.

Delfini e Balene a Pordenone
22 novembre ore 18:00
Ex Convento di San Francesco, Via della Motta, Pordenone
Delfini e balene: mostri da massacrare o esseri senzienti da tutelare?
Attraverso immagini di grande impatto visivo, Giovanni Bearzi illustrerà gli stupefacenti cambiamenti che hanno trasformato il nostro modo di percepire i cetacei. Per secoli "pesci" mostruosi e maligni, animali nocivi da sterminare, prede; oggi "giganti gentili", simpatici cugini acquatici dalle mirabili capacità intellettive, esseri senzienti. Un percorso codificato in termini moderni da pensatori del calibro di Jeremy Bentham e Charles Darwin, che sta entrando a far parte del pensiero scientifico e del sentire comune (con molte contraddizioni).
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. Come è possibile evitarne la scomparsa?
Bearzi, veneziano residente a Cordenons, svolge ricerche sui cetacei del Mediterraneo da trent'anni—di solito da piccole imbarcazioni. Parlerà dello studio dei cetacei in natura, spiegando i suoi metodi di indagine preferiti e come le informazioni acquisite su campo possano contribuire alla tutela di questi affascinanti mammiferi marini.

Pale striped dolphin calf
Today we observed a striped dolphin calf with a rather unusual pale brown pigmentation. No idea why that happened, but the calf looked fine, swimming with mom in a group of about 300 (including many other mother-calf pairs).

What is this sea turtle doing?
What is this loggerhead sea turtle doing? We saw him perform this unusual behaviour for a while, before diving out of sight. Could it be mating with another sea turtle? We have observed a somewhat similar behaviour involving two mating turtles, but both were partly visible at the surface. In this case we are totally ignorant.
