The intertidal decapods in continental Chile are characterized by its species sharing with Peruvian coast along practically all coast, being coexisting species that has not studied with details its interspecific interactions. The aim of the present study is apply null models for understand if the intertidal decapod community is random or not-random. The results revealed that species associations were random, due probably to many species repeated in samples, and the niche sharing results revealed that species reported do not share niche, and in consequence there is not interspecific competition. The obtained results partially agree with other similar observations for Chilean coast, and it would be explained due the oceanographic conditions.
