New records of demosponges (Porifera) from the South Orkney Islands (Antarctica) with a checklist for the region
The South Orkney Islands (SOI) is a poorly studied Antarctic archipelago located in the Scotia Arc. In this study, we added 25 Demospongiae species to the SOI known sponge richness, which was previously represented by only 16 species. Of these, 22 species represent new records for SOI region, althou...
