In order to verify the occurrence of invetebrates associated with macro clusters of Limnoperna fortunei (Dunker, 1857) formed on branches of “sarandi” (Chephalanthus glabratus (Spreng.) K. Schum), quantitative samplings (N=28) were conducted for two years (2002 to 2004) at Veludo Beach on Guaíba Lake (municipality of Porto Alegre, RS, Brazil). From the results, the gastropod Heleobia piscium (Orbigny, 1835) was identified as a constant (78.57%) species, while Potamolithus jacuyensis Pilsbry 1899 (35.71%) and the crustaceous Hyalella curvispina Shoemaker 1942 (26%) were indicated as accessory species. The other taxa were accidental (<25%): Ampullariidae (young individuals), Heleobia davisi (Silva & Thomé, 1985), Chilina parva (Martens, 1868) and Corbicula fluminea (Müller, 1774). Currently, the interspecific relationships among these taxa are poorly known.
