On the Mechanical Properties of Microfibre-Based 3D Chitinous Scaffolds from Selected Verongiida Sponges [PDF]

open access: yesMarine 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 ...

Identification and Current Palaeobiological Understanding of “Keratosa”-Type Nonspicular Demosponge Fossils in Carbonates: With a New Example from the Lowermost Triassic, Armenia [PDF]

open access: yesLife, 2022
Structures similar to fossilized nonspicular demosponges have been reported in carbonates throughout the Phanerozoic and recently in rocks dating back to 890 Ma ago.

New genus and species of lithistid demosponges from submarine caves in Nuku Hiva (Marquesas Islands) and Tahiti Iti (Society Islands), French Polynesia

open access: yesThe European Zoological Journal, 2021
Lithistid demosponges are well known from limestone caves of karstic origin in the Mediterranean Sea. However, they have never been reported from submarine caves of volcanic origin in the South Pacific. Here, we describe and provide DNA barcodes for four

Discovery of chitin in skeletons of non-verongiid Red Sea demosponges [PDF]

open access: yesPLoS 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 ...

Brominated Skeletal Components of the Marine Demosponges, Aplysina cavernicola and Ianthella basta: Analytical and Biochemical Investigations

open access: yesMarine Drugs, 2013
Demosponges possess a skeleton made of a composite material with various organic constituents and/or siliceous spicules. Chitin is an integral part of the skeleton of different sponges of the order Verongida.

Deceptive Desmas: Molecular Phylogenetics Suggests a New Classification and Uncovers Convergent Evolution of Lithistid Demosponges [PDF]

open access: yesPLoS ONE, 2015
Reconciling the fossil record with molecular phylogenies to enhance the understanding of animal evolution is a challenging task, especially for taxa with a mostly poor fossil record, such as sponges (Porifera).

Species-specific community structure in the microbiomes and eukaryotic communities associated with Mediterranean golf ball sponges [PDF]

open access: yesPeerJ
Background Sponges harbor complex and diverse microbiomes that contribute to the host’s fitness and, ultimately, the health of the ecosystems sponges inhabit.

Systematics of ‘lithistid’ tetractinellid demosponges from the Tropical Western Atlantic—implications for phylodiversity and bathymetric distribution [PDF]

open access: yesPeerJ, 2021
Background Among all present demosponges, lithistids represent a polyphyletic group with exceptionally well-preserved fossils dating back to the Cambrian.
