Resumo: 	Benthic macrofauna and meiofauna distribution patterns were  described in a tropical coral  reef (Punta Francés, Cuban  Archipelago, Caribbean Sea). Density and main taxa composition for macrofauna and meiofauna and species diversity and  organismal traits for free-living nematodes were compared among four habitats: seagrass bed, sand flat, dead coral and hard  bottom. Strong spatial patterns of distribution across habitats were detected and explained by a complex combination of  habitat features. Signal/noise ratio for macrofauna data of distribution was enough strong to detect changes across habitats  but the sizes of sampling devices were not adequate to represent the real patterns in the nature. Meiofauna patterns of  distribution were driven by the type of substrate (unconsolidated versus hard bottoms) which surely was in turn dependent of  the hydrodynamic regime. Nematodes dominated in seagrass beds and copepods in the other three habitats. Nematode  density of species and individuals and species richness were highest in unconsolidated habitats maybe due to higher physical  stability, larger spatial niche and more food resource availability. Diversity variation was large and similar between pairs of  habitats with the exception of the hard bottom habitat which had lower differentiation. Most of the nematodes living in hard  substrates showed adaptive organismal traits to cope with hydrodynamic regime and food availability (biofilm/algal turf),  namely small and stout body, teeth for epigrazing, ornamented cuticle and cephalic capsule. Physical control on nematode  assemblages was evident but biotic interactions may play a more important role in seagrass beds and sand flats compared to  hard substrate habitats. The species diversity of nematodes, both in terms of α- and β-diversity, was high at the scale of the  whole Punta Francés coral reef.
