Rapid Decreases and Performance Declines in Northeast Pacific Seamount Foundation Species Detected in an Oxygen Minimum Zone

open access: yesGlobal Change Biology, Volume 32, Issue 4, April 2026.
Across 12 long‐term monitoring sites on three Northeast Pacific seamounts, 163 of 844 cold‐water coral and sponge individuals were lost between surveys 3–5 years apart, with abundance declining at five sites and condition (i.e., health) declining at nine.

Bioremediation Capabilities of Hymeniacidon perlevis (Porifera, Demospongiae) in a Land-Based Experimental Fish Farm

open access: yesJournal of Marine Science and Engineering, 2022
The expansion of aquaculture practices in coastal areas can alter the balance of microbial communities in nearby marine ecosystems with negative impacts on both farmed and natural species, as well as on human health through their consumption.

Associations of Commercial Fisheries and Cold‐Water Corals and Sponges

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 116-129, March 2026.
Three metrics for determining whether the marine life that are landed by commercial fisheries are associated with cold‐water corals and sponges: (a) Adjacent; (b) General Proximity; and (c) Habitat. The relationship between these structure forming invertebrates (SFI) and fisheries is robust across analytical approaches.

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

open access: yesJournal 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 ...

Coralline demosponges ; a geobiological portrait

open access: yes, 2001
The polyphyletic coralline demosponges possess a calcareous basal skeleton of 4 major morphotypes. Each has its own phylogenetic history, with different mechanisms of formation. One extant taxon of each skeletal type has been investigated, and its biochemical (e.g., intracrystalline organic matrix proteins), geochemical (e.g., stable isotopes), and ...

Cytotoxicity and Glycan-Binding Properties of an 18 kDa Lectin Isolated from the Marine Sponge <em>Halichondria </em><em>o</em><em>kadai</em>

open access: yesToxins, 2012
A divalent cation-independent lectin—HOL-18, with cytotoxic activity against leukemia cells, was purified from a demosponge, <em>Halichondria okadai</em>. HOL-18 is a 72 kDa tetrameric lectin that consists of four non-covalently bonded 18 kDa

Sponge community of the western Black Sea shallow water caves: diversity and spatial distribution [PDF]

open access: yesPeerJ, 2018
Marine caves possess unique biocoenotic and ecological characteristics. Sessile benthic species such as sponges associated with cave habitats typically show a marked zonation from the cave entrance towards the end of the cave.

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

open access: yesJournal 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 ...

Genome-wide analysis of the sox family in the calcareous sponge Sycon ciliatum: multiple genes with unique expression patterns

open access: yesEvoDevo, 2012
Background Sox genes are HMG-domain containing transcription factors with important roles in developmental processes in animals; many of them appear to have conserved functions among eumetazoans.

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.
