Macroscopic and microscopic perspectives on habitat-forming Antarctic hexactinellid sponges
Sponges of the class Hexactinellida, commonly known as glass sponges, are conspicuous members of the Antarctic benthos. They grow to considerable sizes and can form dense aggregations on the continental shelf of the Southern Ocean.

The Chemical Ecology of Antarctic Sponges
, 2009 Sponges were collected from shallow waters along the western Antarctic Peninsula near Palmer Station on Anvers Island. The majority (78%) of the sponges were found to have outer tissues defended against the omnivorous, Antarctic sea star Odontaster ...

New Sesterterpenes from the Antarctic Sponge Suberites sp.
Marine DrugsChemical investigation of the Antarctic sponge Suberites sp. has previously led to the identification of new suberitane derivatives, some of which show bioactivity toward respiratory syncytial virus (RSV). Our ongoing NMR-guided investigation of new specimens of the sponge resulted in the isolation of five new analogs (1–5), previously reported ...

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011 A total of 297 bacterial strains were isolated from five Antarctic sponge species and tested by agarose gel electrophoresis for the presence of plasmid molecules. At least one kind of plasmid was carried by 69 isolates (about 23%).

Unlocking Antarctic molecular time-capsules – Recovering historical environmental DNA from museum-preserved sponges [PDF]
Marine sponges have recently emerged as efficient natural environmental DNA (eDNA) samplers. The ability of sponges to accumulate eDNA provides an exciting opportunity to reconstruct contemporary communities and ecosystems with high temporal and spatial ...

Frontiers in Marine SciencePredator-prey interactions in marine ecosystems control population sizes, maintain species richness, and provide intermediate disturbance. Such ecosystem structuring interactions may be rare in Antarctic epibenthic communities, which are unique among ...

Sponges Collected during the Third Indian Antarctic Research Expedition with Description of Isodictya Echinata Sp. Novo [PDF]
, 1986 Six species of sponges collected from the Antarctic Sea off Queen Maud Land (69°54'S and 12°49' E) during the Third Indian Antarctic Research Expedition (December, 1983 to March, 1984) are described with suitable illustrations.
