The area shows a variety of sedimentological characteristics. It predominantly consists of clay with silt and silty clay, but there are also coarse sands with gravel and sandy silt. The marine depths feature muddy biodetritic seabeds, coastal detritus, rocky shallows, and Posidonia oceanica meadows. Cystoseira spp. populations, coralligenous habitats, Lithophyllum byssoides formations and Vada Shoals are present in the area. Moreover, the site is significant for migratory birds and the nesting of rare marine bird species.
