- Abstract
At Horcón beach, Margarita Island, there are sand reefs formed by polychaetes belonging to the Family Sabellariidae, which until now have not been studied, despite their importance as habitat providers for setting and larval settlement of various species, mainly decapod crustaceans. In this sense, the present study aimed to survey decapod crustaceans associated with these reefs. For this, monthly samplings were taken between February and July 2008 and pieces of reef from the subtidal zone were manually collected, at an average between 0.5 and 1 m deep. Samples were transported to the laboratory for processing, extraction and taxonomic determination of the decapod crustaceans present. A total of 1517 individuals of decapod crustaceans were analyzed, belonging to ten families, 15 genera and 27 species. The best represented families were Porcellanidae and Mithracidae with 928 and 298 individuals respectively, followed by Alpheidae (159 ind.), while Processidae, Paguridae and Xanthidae were represented by a single individual each. Moreover, the finding of Alpheus thomasi is the first record for the coast of Venezuela. These reefs appear to be of great importance as substrate protection and shelter for decapod crustaceans.
