"This winter, I collaborated with AMP Regno di Nettuno from the islands of Ischia and Procida, to produce a guide of the most beautiful dives on the two islands," says photographer Pasquale Vassallo. "During a dive at one of the sites, I was on the boat and noticed something strange on the surface. I decided to check what it was. As I swam closer, through the jellyfish, I realised, to my great sadness, that it was a sea turtle carcass. Its carapace was broken, most probably by the propeller of a boat. The animal was also lying in a large amount of rubbish, abandoned in the sea by us humans."
