Tissue composition of sponges from the Weddell Sea, Antarctica: not much meat on the bones [PDF]
The tissue of 31 demosponge and 7 hexachnelhd species was analyzed for its composition of organic and lnorganic matter With one excephon (Hahclona cf gausaana) inorganic matter i e n~ostly the siliceous skeleton, accounted for most of the dry weight ...

Molecular and morphological congruence of three new cryptic Neopetrosia spp. in the Caribbean [PDF]
Neopetrosia proxima (Porifera: Demospongiae: Haplosclerida) is described as a morphologically variable sponge common on shallow reefs of the Caribbean. However, the range of morphological and reproductive variation within putative N.

Establishment of Transgenesis in the Demosponge Suberites domuncula [PDF]
Abstract Sponges (Porifera) represent one of the most basally branching animal clades with key relevance for evolutionary studies, stem cell biology, and development. Despite a long history of sponges as experimental model systems, however, functional molecular studies are still very difficult to perform in these animals. Here, we report

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

Associations of Commercial Fisheries and Cold‐Water Corals and Sponges
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.

Seasonal Growth Rate of the Sponge Haliclona oculata (Demospongiae: Haplosclerida) [PDF]
The interest in sponges has increased rapidly since the discovery of potential new pharmaceutical compounds produced by many sponges. A good method to produce these compounds by using aquaculture of sponges is not yet available, because there is ...
