The SpongeZygomycale parishii(Bowerbank) and its Endobiotic Fauna

摘要: Abstract The endobiotic fauna of the sponge Zygomycale parishii (Bowerbank) was studied for 2·5 years at two sites, Ubatuba and Sao Sebastiao, on northern coast State Paulo, Brazil. Ninety-two macrofaunal species (over 1 mm long) were identified among which Cnidaria, Turbellaria, Nemertinea, Sipuncula, Polychaeta, Mollusca, Crustacea, Pycnogonida, Echinodermata, Ascidiacea Pisces represented. results obtained number (species richness), abundances different faunal composition related to physico-biotic characteristics study sites. influence sample volume other methodological artifacts also examined. ophiuroid Ophiactis savignyi (Muller & Troschell) dominant species, comprising 64% all individuals collected. Sebastiao more diversified than fauna, possibly due higher larval recruitment, closeness Z. sea-floor providing a greater possibility inhabitants this microhabitat find live inside sponge.
