DOIAbstract
The invertebrate benthos, especially the micro- and mesofaunal components, of the Brazilian seas is still poorly known. Relatively few species have been recorded, reflecting the lack of research in this field. The intertidal zone, to depths of about 20 in, has been studied the most, and there the numbers of endemic species are relatively high. The diversity of demersal and pelagic fishes is similar among the major marine regions, and endemism is typically low (<5%) and restricted to reef species. Surveys in southeastern Brazil (depths of up to 2000 in) have recorded more than 1300 species of benthic animals, of which the Porifera, Cnidaria, Sipuncula, Gastropoda, Bivalvia, Scaphopoda, Polychaeta, Crustacea, Ophiuroidea, Bryozoa, and Brachio...
