A therapeutic potential for marine skeletal proteins in bone regeneration [PDF]

open access: yes, 2013
A vital ingredient for engineering bone tissue, in the culture dish, is the use of recombinant matrix and growth proteins to help accelerate the growth of cultivated tissues into clinically acceptable quantities.

Aggregated clumps of lithistid sponges: a singular, reef-like bathyal habitat with relevant paleontological connections.

open access: yesPLoS ONE, 2015
The advent of deep-sea exploration using video cameras has uncovered extensive sponge aggregations in virtually all oceans. Yet, a distinct type is herein reported from the Mediterranean: a monospecific reef-like formation built by the lithistid ...

The Skeletal Amino Acid Composition of the Marine Demosponge Aplysina cavernicola

open access: yesMarine Drugs, 2014
It has been discovered during the past few years that demosponges of the order Verongida such as Aplysina cavernicola exhibit chitin-based skeletons. Verongida sponges are well known to produce bioactive brominated tyrosine derivatives. We could recently

A Comprehensive DNA Barcode Reference Library for the Macroinvertebrates of Scottish Seagrass Beds Using Oxford Nanopore Flongle Flowcells

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
In this study we use ONT Flongle Flowcells to produced DNA barcodes for 146 seagrass associated marine invertebrate OTUs collected from four seagrass beds in Scotland, targeting COI and 18S V4 regions. We generate the first DNA barcode reference library for seagrass beds in Scotland to support future biomonitoring of these priority habitats.

Coralline demosponges ; a geobiological portrait

open access: yes, 2001
The polyphyletic coralline demosponges possess a calcareous basal skeleton of 4 major morphotypes. Each has its own phylogenetic history, with different mechanisms of formation. One extant taxon of each skeletal type has been investigated, and its biochemical (e.g., intracrystalline organic matrix proteins), geochemical (e.g., stable isotopes), and ...

The HMA-LMA dichotomy revisited: an electronmicroscopical survey of 56 sponge species [PDF]

open access: yes, 2014
The dichotomy between high microbial abundance (HMA) and low microbial abundance (LMA) sponges has been long recognized. In the present study, 56 sponge species from three geographic regions (greater Caribbean, Mediterranean, Red Sea) were investigated ...

Bioremediation Capabilities of Hymeniacidon perlevis (Porifera, Demospongiae) in a Land-Based Experimental Fish Farm

open access: yesJournal of Marine Science and Engineering, 2022
The expansion of aquaculture practices in coastal areas can alter the balance of microbial communities in nearby marine ecosystems with negative impacts on both farmed and natural species, as well as on human health through their consumption.

Sponge grade body fossil with cellular resolution dating 60 Myr before the Cambrian [PDF]

open access: yes, 2015
An extraordinarily well preserved, 600-million-year (Myr)-old, three-dimensionally phosphatized fossil displaying multiple independent characters of modern adult sponges has been analyzed by SEM and synchrotron X-ray tomography.

Post‐Embryonic Development and Formation of the Heterocoelic Aquiferous System in Two Species of Calcareous Sponges (Calcarea, Porifera)

open access: yesMolecular Reproduction and Development, Volume 92, Issue 10, October 2025.
ABSTRACT We characterized the morphogenetic processes of larval metamorphosis and the development of the olynthus and heterocoelic aquiferous system (AS) in Sycettusa hastifera (syconoid) and Paraleucilla magna (leuconoid) (Porifera, Calcarea). Metamorphosis and development up to the olynthus were similar in both species.

Revisiting the silicon isotopic signal of sponge skeletons and its implications

open access: yesLimnology and Oceanography, Volume 70, Issue 9, Page 2480-2495, September 2025.
Abstract This study investigates the relationship between the silicon (Si) isotopic composition of sponge skeletal silica (δ30SibSi) and seawater characteristics in sponge habitats, specifically the concentration of dissolved silicic acid and its Si isotopic signature (δ30SidSi).
