Resumen : Three sampling journeys were performed between February and May 2006 aiming to establish Thalassia testudinum prairie structure in Sapzurro Bay. Some physical and chemical parameters were measured in the water over mornings and afternoons within 18 sampling stations. Besides, 9 of the 18 sampling points were located on the external prairie strip while the rest of them were placed on the internal one. It was found that superficial salinity in the Bay varied between 31.65 and 9.73‰ it was the only factor that limited optimum development of prairies. In fact, T. testudinum prairies are distributed between 0.8 m and 2.7 m depth and among the structural variables it was found that biomass dry weight in this area is very low in comparison to other places in the Colombian Caribbean, possibly due to the low salinity levels. However, Kruskall – Wallis test only showed significance between leaves length in the strips (P = 0.0223899) and between strips in low salinity waters (P = 0.0379739).
