Along the coastline rocky cliffs alternate with beaches creating a submarine world ideal to host a rich, varied and flourishing flora and fauna. Near the shore with isolated rocks where the outline is more gentle and flatter within the bathymetry of twenty metres one finds meadows of Posidonia oceanica, beyond thirty metres and down to fifty instead one comes across islands of hard substrate, mainly colonised by the typical settlements of Coralligene. The latter are a notable element of value for biodiversity, among the sessile organisms to be pointed out there is the dominating presence of Paramunicea clavata, better known as Red Gorgonian, but besides other species of Gorgonians, there is no lack of Porifera, such as for instance Axinella polypoides and Spongia agaricina. Seaweed and Bryozoans concur in the formation of the calcareous concretions; these rocks give hospitality to the Madreporeians such as the Cladacora cespitosa, Idroides and Molluscs. For what concerns the marine fauna one can very often come across white sea bream, moray eels, octopus, cuttlefish, conger eels, mullet, scorpion fish and numerous other fish that usually live near the seabed. In free water meetings with dentex, pagari (Sparus caeruleostictus) and sea bream are not rare. Then it is very common to see shoals of black and red Castagnolas (Chromis chromis) and Barracuda, an imported species that is now becoming resident throughout the Ligurian Sea.
