New Zealand Journal of Zoology, Volume 53, Issue 3, September 2026.Rhodolith beds are structurally complex biogenic habitats recognized as important reservoirs of marine biodiversity, yet their associated sponge fauna remains poorly documented in the Southwestern Atlantic. Here, two new species of the genus Clathria Schmidt, 1862 (Microcionidae) are described from mesophotic rhodolith beds off the coast of Pernambuco,

Evaluating 18S Phylogenetic Placement Accuracy to Uncover Hidden Diversity in Non‐Bilaterian Animals
Environmental DNA, Volume 8, Issue 4, July‐August 2026.We assembled the largest curated non‐bilaterian 18S reference dataset and demonstrate that barcode choice strongly influences phylogenetic placement accuracy. Full‐length 18S provides the most robust framework for biodiversity discovery, recovering previously unknown non‐bilaterian lineages, whereas V9 should be interpreted with caution. ABSTRACT Small

Marine silicon for biomedical sustainability
BMEMat, Volume 4, Issue 2, June 2026.Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

Seventeen new complete mtDNA sequences reveal extensive mitochondrial genome evolution within the Demospongiae. [PDF]
PLoS ONE, 2008 Two major transitions in animal evolution--the origins of multicellularity and bilaterality--correlate with major changes in mitochondrial DNA (mtDNA) organization.

Marine Drugs, 2011 While investigating the cytotoxic activity of the methanol extract of an Australian marine sponge Stelletta sp. (Demospongiae), a new diketopiperazine, cyclo-(4-S-hydroxy-R-proline-R-isoleucine) (1), was isolated together with the known bengamides; A (2),

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.Suspended sediment (SS) is a major stressor to coastal marine ecosystems worldwide, with SS loads expected to increase under future anthropogenic and climatic pressures. Sponges, as obligate filter feeders, are often assumed to be sensitive to elevated SS, yet responses vary widely among species, and little is known about physiological impacts of SS ...

Phylogenetic classification of the Halichondrids (Porifera, Demospongiae).
Beaufortia, 1990 Using a multicharacter approach and numerical cladistic computer programs a phylogenetic analysis is made of a newly defined order Halichondrida (which includes all Halichondrida and parts of the Axinellida sensu Lévi, 1973), with emphasis on the newly defined family Halichondriidae (which includes the families Halichondriidae and Hymeniacidonidae ...
