The geomorphology of these islands coasts create various habitats for the marine and also terrestrial flora and fauna. In the archipelago's sheltered waters, important marine predator species being on the top of the food chain are resident or common, indicating the area's biological richness. Especially Delphinus delphis is present in the site with one of its last 3-4 spot populations in the whole Mediterranean.
