Previous records of associations between these carideans and other hosts were revised and the possible type of association between the shrimps and their hosts is discussed. he occurrence of the sponge A. viridis in the Abrolhos Archipelago is also reported for the irst time. KEY WORDS Caridea, Anchistioididae, Palaemonidae, Demospongiae, symbiosis. Despite being less numerous than free-living species, symbiotic decapod crustaceans are quite common and this lifestyle has evolved independently in several taxa within the group (Bauer, 2004; Baeza et al., 2011). Among decapods, caridean shrimps have been commonly reported in association with larger invertebrates and even with ishes (e.g., Castro, 1971; Bruce, 1976; Knowlton and Keller, 1983; Karplus, 1987; Bauer, 2004).
