GUEST BLOGGER ROBERTO MASCIA​

Picture
My name’s Roberto I’m 37 years and I’m from Naples, Italy. I love sharks since I saw for the first time on tv the Spielberg’s movie JAWS in 1986. From then I study them with passion, love and devotion. I love all species of sharks and one of my dreams is to go to South Africa to dive myself with white sharks or cooperate in some way with some specialized association.
