This marine area, with 17 385 hectares and unusual seabed in coastal areas, hosts a variety of large organisms, from unicellular algae and crustaceans up to large pelagics that sometimes visit the area in search of higher food concentrations.

In geological terms, we can find interesting structures, such as abrasion holes ("giant pits") and a series of rocky outcrops unevenly distributed.

The fauna is diverse and are observable shoals of Pseudocaranx dentex, Seriola spp., Sarda, Sphyraena viridensis, Katsuwonus pelamis and Epinephelus marginatus and other species as Mobula tarapacana, Caretta  caretta and Tursiops truncatus.

As for the marine flora, prevails the calcareous encrusting red-algae, the algae Padina pavonica, and also enigmatic coral such as the Antipathella wollastoni, colourful sponges or graceful hydrozoans (for example, Nemertesia spp.).
