I'm an Italian underwater naturalist photographer expert of identifications of Mediterranean's fish (currently I'm mainly interested to the Gobiidae) and echinoderms (mainly genus Astropecten and Holothuria).
With global warming and the entry of many species from other seas, I deeped my knowledge also of many Gobiidae and benthic fish of Indo-Pacific.

I am coauthor in peer-reviewed articles:
