Pumping Rate and Size of Demosponges—Towards an Understanding Using Modeling

open access: yesJournal of Marine Science and Engineering, 2021
Filter-feeding sponges pump large amounts of water and contribute significantly to grazing impact, matter transport and nutrient cycling in many marine benthic communities.

Moving Beyond Morphology: Genomic Insights Into Evolutionary Histories of Haplosclerid Sponges

open access: yesZoologica 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.

In situ Pumping Rate of 20 Marine Demosponges Is a Function of Osculum Area

open access: yesFrontiers in Marine Science, 2021
Sponges play a key role in the transfer of energy and nutrients into many benthic ecosystems, and the volume of water they process is an important regulator of these fluxes. Theoretical scaling relationships between sponge volume, osculum cross-sectional

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

open access: yesJournal 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.

Shedding Light on the Italian Mesophotic Spongofauna

open access: yesJournal of Marine Science and Engineering
An analysis of 483 remotely operated vehicle (ROV) dives carried out along the Italian coast on hard substrata at mesophotic depths (40–200 m) allowed an overview of the rich sponge diversity (53 taxa) of the deep continental platform to be obtained for ...

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

open access: yesMolecular 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.

Collagens of Poriferan Origin

open access: yesMarine Drugs, 2018
The biosynthesis, structural diversity, and functionality of collagens of sponge origin are still paradigms and causes of scientific controversy. This review has the ambitious goal of providing thorough and comprehensive coverage of poriferan collagens ...

Bacterial precursors and unsaturated long-chain fatty acids are biomarkers of North-Atlantic deep-sea demosponges.

open access: yesPLoS ONE, 2021
Sponges produce distinct fatty acids (FAs) that (potentially) can be used as chemotaxonomic and ecological biomarkers to study endosymbiont-host interactions and the functional ecology of sponges.
