The sea of San Giorgio is charactarised by crystal clear water and amazing seabed: this one is made up of fine gravel close to the coast, while if you swim further, you will find sand. The marine fauna is various:among rocks and ravines you can find typical species of these habitat like Murena Helena, butterfly blenny, gudgeon, conger, dusky gropuer (Epinephelus marginatus).
Other species enlighten the sand with bright colours like Ornate wrasse (Thalassoma pavo), mediterranean rainbow wrass (Coris Julis), peacock wrasse (Simphodus tinca). But the queen of the sea of San Giorgio is the saddled seabream (Oblada melanura), whose presence prevails in our waters. Thanks to the clearness of the sea, you can observe with naked eye the saddled seabream and whitebait – another typical specie of our sea.
Species like Chromis Chromis (damselfish) and the striped bream hide among the seagrass bushes. Different species of sargos and other fishes swim in our sea: two-banded seabream (Diplodus vulgaris), white seabream (Diplodus sargus), annular seabream (Diplodus anularis), the garfish, salema porgy, mullet (Mugil cephalus), flying fish (Dactylopterus volitans), the Percon gibbes, which is a type of crab, also know as atlantic crab runner. The aquatic plant Posidonia oceanica keeps the right temperature of the sea and it creates green underwater meadows in not very deep waters with sandy seabed.
