Direct Development of Golf Ball Sponges, Genus Craniella (Demospongiae, Tetractinellida) From the Northeast Atlantic Ocean. [PDF]
Mol Reprod DevABSTRACT Among the eight types of development in sponges, the least common and least studied is direct, non‐larval development during viviparity. To supplement our knowledge of this rare type of demosponge development, we present here a description of the embryonic development of four species of the genus Craniella (Demospongiae, order Tetractinellida)

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 ...

Antifouling activity of twelve demosponges from Brazil [PDF]
Brazilian Journal of Biology, 2013 Benthic marine organisms are constantly exposed to fouling, which is harmful to most host species. Thus, the production of secondary metabolites containing antifouling properties is an important ecological advantage for sessile organisms and may also ...

Electrolysis as a Universal Approach for Isolation of Diverse Chitin Scaffolds from Selected Marine Demosponges. [PDF]
Mar Drugs, 2022 Three-dimensional chitinous scaffolds often used in regenerative medicine, tissue engineering, biomimetics and technology are mostly isolated from marine organisms, such as marine sponges (Porifera).

Systematics of ‘lithistid’ tetractinellid demosponges from the Tropical Western Atlantic—implications for phylodiversity and bathymetric distribution [PDF]
PeerJ, 2021 Background Among all present demosponges, lithistids represent a polyphyletic group with exceptionally well-preserved fossils dating back to the Cambrian.

Organic Geochemistry, 1999 The lipid assemblages of the "living fossil" stromatoporoid Astrosclera willeyana (Great Barrier Reet) and the demosponge Agelas aroides (Mediterranean Sea) were investigated. Large amounts of branched carboxylic acids are present in the sponges studied.

A Review on Genus Halichondria (Demospongiae, Porifera)
Journal of Marine Science and Engineering, 2022 Demosponges of the genus Halichondria Fleming (1828) are common in coastal marine ecosystems worldwide and have been well-studied over the last decades.

Demospongic Acids Revisited [PDF]
Marine Drugs, 2010 The well-known fatty acids with a D5,9 unsaturation system were designated for a long period as demospongic acids, taking into account that they originally occurred in marine Demospongia sponges. However, such acids have also been observed in various marine sources with a large range of chain-lengths (C16–C32) and from some terrestrial plants with ...

A genomic view of the microbiome of coral reef demosponges [PDF]
The ISME Journal, 2021 Abstract Sponges underpin the productivity of coral reefs, yet few of their microbial symbionts have been functionally characterised. Here we present an analysis of ~1200 metagenome-assembled genomes (MAGs) spanning seven sponge species and 25 microbial phyla.
