This work aims to present the biodiversity of the ficologic flora of Cibratel Beach, located in the Cibratel neighborhood, in the city of Itanhaém, SP, with geographic coordinates 24º12’00 “S and 46º48’39” W, with subtropical humid climate (Cfa), with average annual temperature of 22ºC and rainfall of 2000-2500 mm / year. The interest in this place is due to its rich biodiversity. The samplings carried out, have followed a seasonality. We performed 07 samplings on the following dates 08/07/2017, 09/09/2017, 04/11/2017, 04/12/2017, 01/13/2018, 04/29/2018 and 06/17/2018, in these one can observe a great variety of species, one persisting throughout the period, others only observed in only one opportunity. As for the fauna, we find bryozoans, enteroprocts, sponges, mollusks, birds, anemones, sea urchins, turtles, crustaceans, loons, buzzards, biguas, atobas, sea cucumbers, aplysia, herons and seagulls. The sampling process was done by scraping the substrate with the aid of a spatula, in order to collect the alga as a whole, without damaging any part of the material, the storage was carried out in plastic bags and conditioned in a freezer until identification, after which, with the aid of specialized bibliography, the samples were placed in 4-5% formalin polypropylene flasks. To date, 41 genre and 61 species have been identified
