Draft genomes shed light on the dual bacterial symbiosis that dominates the microbiome of the coral reef sponge Amphimedon queenslandica

Frontiers in Marine Science, 2016
Amphimedon queenslandica is a coral reef demosponge that houses a low complexity and low abundance microbiota dominated by a proteobacterial duo for which draft genomes are presented here.

First report of Crumillospongia (Demospongea) from the Cambrian of Europe (Murero biota, Spain) [PDF]

, 2011
The demosponge genus Crumillospongia, originally described from the Burgess Shale (middle Cambrian of Canada), has only been cited from lower and middle Cambrian localities of North America and China.

The complete mitochondrial genome of sponge Halichondria sp. (Demospongiae, Suberitida, Halichondriidae) from Dok-do

Mitochondrial DNA. Part B. Resources, 2019
The mitogenome sequence of Halichondria sp. was determined for the first time in this study. Specimens were identified as a new species belonging to genus Halichondria and more detailed taxonomic study is ongoing.

Divergence times in demosponges (Porifera): first insights from new mitogenomes and the inclusion of fossils in a birth-death clock model

BMC Evolutionary Biology, 2018
Background Approximately 80% of all described extant sponge species belong to the class Demospongiae. Yet, despite their diversity and importance, accurate divergence times are still unknown for most demosponge clades.

Sponge Takeover from End-Permian Mass Extinction to Early Induan Time: Records in Central Iran Microbial Buildups

Frontiers in Earth Science, 2021
The end-Permian mass extinction was the most severe biotic crisis in Earth’s history. In its direct aftermath, microbial communities were abundant on shallow-marine shelves around the Tethys.

The complete mitochondrial genome of sponge Pseudosuberites sp. (Demospongiae, Suberitida, Suberitidae) from Dokdo, Republic of Korea (East Sea)

Mitochondrial DNA. Part B. Resources, 2019
The mitogenome of Pseudosuberites sp. (Suberitida, Suberitidae) has been determined first in the genus Pseudosuberites. Assembled mitogenome was 23,502 bp in length, including 14 protein-coding genes, 25 transfer RNA, and 2 ribosomal RNA genes. The order

Agelasine Diterpenoids and Cbl-b Inhibitory Ageliferins from the Coralline Demosponge Astrosclera willeyana

Marine Drugs, 2021
An extract of the coralline demosponge Astrosclera willeyana inhibited the ubiquitin ligase activity of the immunomodulatory protein Cbl-b. The bioassay-guided separation of the extract provided ten active compounds, including three new N-methyladenine ...

Taxonomical and biogeographical notes on the sponges of the Strait of Magellan

Scientia Marina, 1999
The sponge material from the Straits of Magellan collected by the research vessels Cariboo in 1991 and Victor Hensen in 1994, and by a shallow water diving team, were studied.

Filtration Rates and Scaling in Demosponges

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.
