Biocenosis of Mediterranean infralittoral algae

Description (English)

This biocenosis is located in the infralittoral stage. The infralittoral stage extends from areas where only accidentally does something emerge above the water, to the survival limit of the marine phanerogams and the photophilous algae. This lower limit depends on the penetration of light, and thus varies greatly with the topography and the quality of the water. In areas of very clear water, it can go down to 35-40 meters, whereas it is restricted to only a few meters in turbid areas. All the rocky substrata of the infralittoral stage where the conditions of the stage prevail are covered with many different photophilous algae, an extremely rich population.
