Shallow reefs on the coast of Paraíba state are poorly known. An analysis at three stations (Prot = protected; SP = semi-protected; Exp = exposed) with different gradients of wave exposure revealed significant (p < 0.05) differences related to the biomass of seaweed (Prot = SP ≠ Exp). Station Exp with 9.97g (23%) presented the lowest value followed by SP with 10.93 (25%) and Prot with 22.55g (52%). The values suggest that the biomass of seaweeds is inversely related to the gradative higher exposure to waves. Additionally, a first record of Wrangelia argus (Montagne) Montagne was made for the coast of Paraíba.
