First Report on Chitin in a Non-Verongiid Marine Demosponge: The Mycale euplectellioides Case
Marine Drugs, 2018 Sponges (Porifera) are recognized as aquatic multicellular organisms which developed an effective biochemical pathway over millions of years of evolution to produce both biologically active secondary metabolites and biopolymer-based skeletal structures ...

Microbiome changes in the sponge Halichondria panicea along the Baltic Sea salinity gradient
Frontiers in MicrobiologyThe Baltic Sea is characterized by a strong salinity gradient, which impacts the diversity and composition of free-living macro- and microorganisms. Much less is known about how host-associated microorganisms are affected by decreasing salinities. Marine

Journal of Biogeography, Volume 53, Issue 1, January 2026.ABSTRACT Aim Genetic connectivity and local adaptation were examined across the distribution of the freshwater sponge Ephydatia muelleri. Because it occupies an exceptional breadth of freshwater environments across a broad geographic range, this species offers key insights into biogeographic processes shaping genetic structure and adaptation in inland ...

Diverse RNA interference strategies in early-branching metazoans
BMC Evolutionary Biology, 2018 Background Micro RNAs (miRNAs) and piwi interacting RNAs (piRNAs), along with the more ancient eukaryotic endogenous small interfering RNAs (endo-siRNAs) constitute the principal components of the RNA interference (RNAi) repertoire of most animals.

Corallistin A, a second example of a free porphyrin from a living organism : isolation from the demosponge Corallistes sp. of the coral see and inhibition of abnormal cells [PDF]
, 1989 It is shown that the demosponge #Corallistes$ sp. (#Tetractinomorpha$, #Lithistida$, #Corallistidae$) collected in the Coral Sea, contains corallistin A, the second example, of a free porphyrin from a living organism.

Moving Beyond Morphology: Genomic Insights Into Evolutionary Histories of Haplosclerid Sponges
Zoologica Scripta, Volume 55, Issue 1, Page 177-194, January 2026.ABSTRACT Accurate taxonomic identification is essential for defining species boundaries and understanding biodiversity. However, this remains challenging for groups where morphological character evolution is poorly understood or diagnostic traits are absent.

Benthic foraminifers and siliceous sponge spicules assemblages in the Quaternary rhodolith rich sediments from Pontine Archipelago shelf [PDF]
, 2016 The bottom samples (Quaternary in age) of two cores (CS1 and Caro1) collected at 60 and 122 m water depth in the marine area near Ponza Island (Pontine Archipelago, Tyrrhenian Sea) are investigated.

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 ...
