Checklist of the marine Bryozoa from Uruguay (Southwest Atlantic)

Knowledge of the marine bryozoan fauna Uruguay is mostly based on scattered records found in local faunistic surveys and taxonomic results two oceanographic cruises to Southwest Atlantic, but a comprehensive study has not yet been published for this area. This paper aims compile an updated checklist, bringing together all information about Uruguayan fauna. Of 73 recorded taxa, 30 (41%) are known only from deep waters off Río de la Plata. Even considering undetermined species, these show high degree endemism as it was already shown several other benthic groups such Bivalvia, Ascidiacea Pycnogonida. The absence taxonomists bryozoans resulted unprecedented situation that deep-sea better than coastal shelf representatives phylum. main conclusion faunal compilation efforts should be made coordinate gathering shallow collections bridge present knowledge gap biodiversity important group invertebrates.
