Phylogenetic classification of the Halichondrids (Porifera, Demospongiae).

Beaufortia, 1990
Using a multicharacter approach and numerical cladistic computer programs a phylogenetic analysis is made of a newly defined order Halichondrida (which includes all Halichondrida and parts of the Axinellida sensu Lévi, 1973), with emphasis on the newly defined family Halichondriidae (which includes the families Halichondriidae and Hymeniacidonidae ...

A New Diketopiperazine, Cyclo-(4-S-hydroxy-R-proline-R-isoleucine), from an Australian Specimen of the Sponge Stelletta sp.

Marine Drugs, 2011
While investigating the cytotoxic activity of the methanol extract of an Australian marine sponge Stelletta sp. (Demospongiae), a new diketopiperazine, cyclo-(4-S-hydroxy-R-proline-R-isoleucine) (1), was isolated together with the known bengamides; A (2),

Low Abundance Taxa Show Diverse Microbial Symbiotic Interactions With the Freshwater Sponge, Radiospongilla crateriformis, Pre and Post Gemmulation

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
The microbiome profile of freshwater sponges did not broadly change in taxonomy or functional profile based on metatranscriptome analysis prior to and after formation of sponge dormant bodies (gemmules). Results highlight a subset of taxa that likely associate with the sponge host in different ways from facultative to long‐term symbionts.

Localization and Characterization of Ferritin in Demospongiae: A Possible Role on Spiculogenesis [PDF]

Marine Drugs, 2014
Iron, as inorganic ion or as oxide, is widely used by biological systems in a myriad of biological functions (e.g., enzymatic, gene activation and/or regulation). In particular, marine organisms containing silica structures—diatoms and sponges—grow preferentially in the presence of iron. Using primary sponge cell culture from S. domuncula–primmorphs—

Barcoding‐Inferred Biodiversity of Shallow‐Water Indo‐Pacific Demosponges

Journal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim The Indo‐Pacific is the world's largest marine biogeographic region. It is characterised by different degrees of connectivity among its subregions and harbours the majority of demosponge species currently known to science. Comparisons between regional sponge faunas have been undertaken in the past, mostly based on morphological species ...

Examining Marine Assemblages Across an Inverse Salinity Gradient

Molecular Ecology, Volume 35, Issue 6, March 2026.
ABSTRACT Salinity gradients and fluctuations can create a natural ecological filter, with few species tolerating salinity above 50 practical salinity units (PSUs). We investigated how an inverse salinity gradient affected marine community diversity and composition in Shark Bay, a remote hypersaline coastal embayment in Western Australia.

Microbial diversity in four Mediterranean irciniid sponges [PDF]

Biodiversity Data Journal
This paper describes a dataset of microbial communities from four different sponge species: Ircinia oros (Schmidt, 1864), Ircinia variabilis (Schmidt, 1862), Sarcotragus spinosulus Schmidt, 1862 and Sarcotragus fasciculatus (Pallas, 1766).

Environmental DNA as a Tool for the Assessment of Coral (Anthozoa) Composition in the Chagos Archipelago

Environmental DNA, Volume 8, Issue 1, January–February 2026.
Environmental DNA (eDNA) metabarcoding using ITS2 markers reliably recovered 18 coral genera, with strong overlap but also complementary detections compared to benthic transect surveys. eDNA uniquely identified several cryptic genera, while some common genera were only recovered by traditional surveys, highlighting method‐specific biases.

Gems From the Caves: Genomic Insights Into the Biosynthetic Potential of Antimicrobial‐Producing Bacteria Associated With Tropical Cave‐Dwelling Sponges

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Our study reveals that cave‐dwelling marine sponges host bacteria with antimicrobial activity against multidrug‐resistant strains. The bioactive Pseudomonadaceae strains exhibited biosynthetic clusters encoding both characterized and putative antimicrobial compounds and peptides. The findings highlight their potential for discovering novel biomolecules

Transcriptomic Insights Into the Immune Repertoire of an Antarctic Sponge

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Antarctic marine sponges are essential components of the benthic fauna, playing a crucial role in structuring this ecosystem through their own biological activities and their symbiotic relationships with diverse microorganisms. Yet, the transcriptional repertoire and the immune responses associated with interactions with microorganisms in this unique ...
