Filtration Rates and Scaling in Demosponges [PDF]
Journal of Marine Science and Engineering, 2022 Demosponges are modular filter-feeding organisms that are made up of aquiferous units or modules with one osculum per module. Such modules may grow to reach a maximal size.

Lithistid Demosponges of Deep-Water Origin in Marine Caves of the North-Eastern Mediterranean Sea
Frontiers in Marine Science, 2021 Desmas-bearing demosponges known as lithistids have heavily silicified skeleton and occur typically in bathyal environments of warm and tropical areas but may be found in certain shallow marine caves.

On the Mechanical Properties of Microfibre-Based 3D Chitinous Scaffolds from Selected Verongiida Sponges [PDF]
Marine Drugs, 2023 Skeletal constructs of diverse marine sponges remain to be a sustainable source of biocompatible porous biopolymer-based 3D scaffolds for tissue engineering and technology, especially structures isolated from cultivated demosponges, which belong to the ...

Discovery of chitin in skeletons of non-verongiid Red Sea demosponges [PDF]
PLoS ONE, 2018 Marine demosponges (Porifera: Demospongiae) are recognized as first metazoans which have developed over millions of years of evolution effective survival strategies based on unique metabolic pathways to produce both biologically active secondary ...
