Lower biomass of Ophiacantha vivipara (Ljungman, 1870) (ophiuroid) and Porifera, as well as the scarcity of the ascidian Paramolgula gregaria were detected in zones CFE (Fig.
Arthropoda had the highest number of taxa (161 taxa; mostly Crustacea), followed by Annelida (122; mostly Polychaeta), Mollusca (114; mostly Bivalvia and Gastropoda), Bryozoa (50), Echinodermata (43), Cnidaria, both Anthozoa and Hydrozoa (27), and other phyla with one to three taxa (Brachiopoda, Cephalorhyncha, Entoprocta, Nemertea, Platyhelminthes, Porifera, Sipuncula).
According to Rocha (2002), only 30% of the freshwater invertebrate diversity is presently known and some taxon as Porifera, Cnidaria, Platyhelminthes, Nemertea, Nematoda, Nematomorpha, Bryozoa, Annelida and several insect groups need specialists, collections and/or minimum updated information on identification, distribution and autoecology.
