Perhaps the most surprising wonders of the island of San Pietro lie beneath the surface of the water: an extraordinary spectacle of blue, of light, and life.
The glittering shoals of saddled bream, the large solitary bream, the suspicious gilthead bream that splash away; on the shore, the small Sand Steenbras that graze confidently between the feet of the swimmers; further on the undulating posidonia meadows – dark spots on the emerald sandy bottom – where rock fish find safe shelter. Offshore, the silvery Barracuda formations flash by and the mighty “running tuna” cross their path when their season arrives. And down on the seabed, in the ups and downs of the shallows, it is not uncommon to come across large groupers or lobsters moving sideways, among the thousands of colours of sponges and the bright red gorgonians and corals clinging to the sides of the submerged rocks.
