The seabed is rocky and irregular, with walls, boulders, caves and crevices. In this area, the seabed is rocky and irregular, presenting walls, boulders, caves and crevices. This protected area also presents varied biologic and geologic characteristics, housing a large diversity of marine species, from small algae and invertebrates to big pelagic fish and migratory animals that visit the area searching for large concentrations of food.

The sediment relief, firmness and stability are very variable. Some bottom parts are covered by blocks that are established either on bedrock or in sediment. The sediment bottom is stable, generally composed of medium and/or rough sand, mineral and well calibrated, and it can form waves and have variable firmness, also may be found in valleys or covering the bedrock and the blocks. Low places have an irregular crown, marked by ridges and valleys, also with irregular surface.

The most frequent fish species are the Abudefduf luridus, the Coris julis, the Labrus bergylta, the Serranus atricauda, the Epinephelus marginatus and the Sparisoma cretense. In the crevices are common the Gymnothorax unicolor, the Muraena augusti and Phycis phycis. In the water column are abundant the Boops boops, the Balistes capriscus and the Pseudocaranx dentex.

Concerning the algae, are characteristic the chlorophyte Codium adhaerens and the rhodophyte Pterocladiella capillacea and Porphyra sp. In lower depths, are the rhodophyte Sphaerococcus coronopifolius and the phaeophyceae Cladostephus spongiosus, Padina pavonica and Zonaria tournefortii.

It is possible to see this area through the Fajã Grande - Ponta Delgada (PR01FLO) and the Great Route of Flores (GR01FLO) walking trails.
