The site delineates a stretch of seabed which is at the north of the Capo Vaticano promontory; this zone hosts an important Posidonia oceanica area in good conservation status. The beaches in this coastal stretch have good lateral continuity, directly fed by sediments which are carried by the nearby Potame Stream. During storms, these sediments are transported along the coastline in parallel and perpendicular directions to the coast. This is due to wave action which form seafloor morphologies like bars, megaripples and ripples that are easily recognised as they are located just a few meters below the sea surface. Several cetacean species have been observed in the site.
