ABSTRACT
This study determined the population profile of echinoderms in Culliatan, San Joaquin, Iloilo in terms of species diversity, population density, and population abundance. Three study sites were studied. It was hypothesized that there exists no significant difference in the population profile of echinoderms among the three sites studied. Statistical tools employed in this study were mean, standard deviation, and the Kruskal-Wallis Test, which was set at 0.05 level of significance. Among the three study sites, measuring 100 square meters each, the only echinoderm species present was the sea urchin (Class Echinoidea), with average abundance of 213 and population density of 2.13.
