I'm an Italian underwater naturalist photographer expert of identifications of Mediterranean's fishes (currently I'm mainly interested to the Gobiidae) and echinoderms (mainly genus Astropecten and Holothuria).

I am coauthor in peer-reviewed articles:

I wrote an article to explain the identification's keys for Mediterranean's Astropecten:
