“…Sponges form symbiotic relationships with often complex communities of microorganisms ( 25 – 30 ). Up to 40% to 60% of the tissue volume of certain sponge species can consist of microorganisms at a density exceeding 10 9 microbial cells per mL of sponge tissue, orders of magnitude greater than concentrations in surrounding seawater or sediment ( 31 – 33 ).…”

“…The associated microbes produce diverse metabolites that have stimulated the interest of the pharmaceutical industry ( 34 – 38 ). Typically, the prokaryotic composition of sponge microbiomes is analyzed by high-throughput 16S rRNA gene-based sequencing approaches ( 27 – 30 , 39 – 43 ). Recently, metagenomic sequencing provided new insights into the functional gene repertoires of sponges and the metabolic pathways carried by sponge symbionts ( 26 , 44 – 46 ).…”

Calcareous sponges are an often overlooked element of sponge communities. In contrast to most other sponges, calcareous sponges produce calcium carbonate spicules, as opposed to the siliceous spicules of most sponges. Here, we investigated bacterial communities of 17 sponge species, including type and paratype specimens of recently described calcareous species, sampled off the remote island of Rodrigues, in the Indian Ocean. The main axis of variation in a PCO analysis of all samples separated non-calcareous sponge species including Axinyssa aplysinoides, Cinachyrella aff. australiensis, Petrosia seychellensis, Ircinia aff. variabilis, Spongia ceylonensis, Plakinastrella aff. clipptertonensis, Agelas aff. ceylonesis, Agelas aff. Mauritiana, and Hyrtios erectus from calcareous sponges, the non-calcareous Biemna tubulata, sediment and seawater. Overall, the bacterial communities of calcareous sponges revealed unique prokaryotic profiles with low abundances of several bacterial phyla, and relatively high abundances of other taxa e.g. the phyla Fibrobacterota, Proteobacteria, and SAR324 clade, the class Alphaproteobacteria and orders Cytophagales and Cyanobacteriales, although there was considerable variation among species. Calcareous sponges also had a high dominance of unknown bacterial operational taxonomic units (OTUs). Considering the unique nature of these communities, further studies are needed to better understand the environmental and ecological drivers of calcareous sponge-associated bacterial communities and their relevance as potential sources of novel microbes of biotechnological interest.

In this study, we present the first integrative revision of the Boreal and Arctic calcareous sponges of the genus Leucosolenia with a specific focus on its biodiversity in the White Sea. The material for this work included a combination of newly collected specimens from different regions of the North-East Atlantic and the White Sea and historical museum collections. An integrative analysis was implemented based on vast morphological data (light microscopy, scanning and transmission electron microscopy), microbiome observations, ecological data, accompanied by molecular phylogenetic and species’ delimitation analyses based on three nuclear markers (28S rRNA, 18S rRNA, and histone 3). We demonstrate that Leucosolenia complicata, previously reported from Arctic waters, is restricted to the North-East Atlantic, while in the Arctic, Leucosolenia diversity is represented by at least four species: Leucosolenia corallorrhiza, Leucosolenia variabilis, and two new species, one of which is described herein under the name Leucosolenia creepae sp. nov.. The molecular phylogeny analysis supports the species identity of these species. In addition to conventional morphological characters, new informative fine morphological characters (skeleton and oscular crown organization; cytological structure, including morphotypes of symbiotic bacteria) were found, providing a baseline for further revision of this group in other regions.
