Hydroid assemblages from the Southwestern Atlantic Ocean (34–42° S)
Abstract This paper provides updated taxonomic knowledge about hydrozoan species and provides ecological information including geographical and bathymetric distributions and biological substrata for the various hydroid assemblages from the Sub‐Antarctic Biogeographical Region, mainly Buenos Aires an...
