The meeting will take place at Cala Sidoti, within the "A" area of the first Marine Protected Area in Italy. The area is easy to access and is characterized by a similar beach made up of small gray-pearly grains of basalt that do not remain attached to the costume. Equipped with mask and snorkel we will go into its very shallow waters where we touch and it is not necessary to dive deep; We will then observe on the surface of the water the rich fauna and flora where we will discover, the dens of the Groupers, expanses of poseidonias where the salps sneak, shallow waters full of sea urchins and many other species. We will also discover different social behaviors and cunning survival strategies, and we will understand that fish are much smarter than they say :)
