3D Chitin Scaffolds of Marine Demosponge Origin for Biomimetic Mollusk Hemolymph-Associated Biomineralization Ex-Vivo

Marine Drugs, 2020
Structure-based tissue engineering requires large-scale 3D cell/tissue manufacture technologies, to produce biologically active scaffolds. Special attention is currently paid to naturally pre-designed scaffolds found in skeletons of marine sponges, which

Genomic Connectivity and Adaptation Signals of the Freshwater Sponge Ephydatia muelleri Across Its Distribution

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 ...

Demosponge diversity from North Sulawesi, with the description of six new species

ZooKeys, 2017
Sponges are key components of the benthic assemblages and play an important functional role in many ecosystems, especially in coral reefs. The Indonesian coral reefs, located within the so-called “coral triangle”, are among the richest in the world ...

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.

Contraction-Expansion and the Effects on the Aquiferous System in the Demosponge Halichondria panicea

Frontiers in Marine Science, 2020
Contractile behavior is common among sponges despite their lack of nerves and muscles. As sessile filter-feeders, sponges rely on water with suspended food particles being pumped through their aquiferous system.

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 ...

The ontogeny of choanocyte chambers during metamorphosis in the demosponge Amphimedon queenslandica

EvoDevo, 2016
Background The aquiferous body plan of poriferans revolves around internal chambers comprised of choanocytes, a cell type structurally similar to choanoflagellates.

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 8, Page 505-516, December 2025.
Epithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.

Determination of the Halogenated Skeleton Constituents of the Marine Demosponge Ianthella basta

Marine Drugs, 2017
Demosponges of the order Verongida such as Ianthella basta exhibit skeletons containing spongin, a collagenous protein, and chitin. Moreover, Verongida sponges are well known to produce bioactive brominated tyrosine derivatives.

Methylome Profiling of a Deuterostome Invertebrate Using Oxford Nanopore Technology (ONT)

Molecular Ecology Resources, Volume 25, Issue 8, November 2025.
ABSTRACT DNA methylation is crucial for genome regulation and provides key insights into the interaction between genetics and environmental factors, offering valuable perspectives for ecological research. However, knowledge of DNA methylation patterns in nonmodel invertebrates remains limited.
