Viral ecogenomics across the Porifera [PDF]

open access: yesMicrobiome, 2020
Viruses directly affect the most important biological processes in the ocean via their regulation of prokaryotic and eukaryotic populations. Marine sponges form stable symbiotic partnerships with a wide diversity of microorganisms and this high symbiont ...

Porifera

open access: yesHandbook of Marine Model Organisms in Experimental Biology, 2021
Poriferans (sponges) are sessile aquatic (largely marine) animals that are found in almost all benthic habitats. There are an estimated 15,000 species living today, although many have not been described (reviewed in Hooper and Van Soest 2002). The sponge body plan is amongst the simplest in the animal kingdom and lacks nerve and muscle cells and a ...

Proposal for a revised classification of the Demospongiae (Porifera) [PDF]

open access: yesFrontiers in Zoology, 2015
BackgroundDemospongiae is the largest sponge class including 81% of all living sponges with nearly 7,000 species worldwide. Systema Porifera (2002) was the result of a large international collaboration to update the Demospongiae higher taxa ...

MRTF specifies a muscle-like contractile module in Porifera

open access: yesNature Communications, 2022
Muscle-based movement is a hallmark of animal biology, but the evolutionary origins of myocytes are unknown. Although believed to lack muscles, sponges (Porifera) are capable of coordinated whole-body contractions that purge debris from internal water ...

Plastics in Porifera: The occurrence of potential microplastics in marine sponges and seawater from Bocas del Toro, Panamá

open access: yesPeerJ, 2021
Microplastics (MP) are now considered ubiquitous across global aquatic environments. The ingestion of MP by fish and other marine vertebrates is well studied, but the ingestion of MP by marine invertebrates is not.

A Review on Genus Halichondria (Demospongiae, Porifera)

open access: yesJournal of Marine Science and Engineering, 2022
Demosponges of the genus Halichondria Fleming (1828) are common in coastal marine ecosystems worldwide and have been well-studied over the last decades.

The Molecular Machinery of Gametogenesis in Geodia Demosponges (Porifera): Evolutionary Origins of a Conserved Toolkit across Animals

open access: yesMolecular biology and evolution, 2020
All animals are capable of undergoing gametogenesis. The ability of forming haploid cells from diploid cells through meiosis and recombination appeared early in eukaryotes, whereas further gamete differentiation is mostly a metazoan signature ...

Hg Levels in Marine Porifera of Montecristo and Giglio Islands (Tuscan Archipelago, Italy)

open access: yesApplied Sciences, 2020
Porifera are filter-feeding organisms known to bioaccumulate different contaminants in their tissues. The presence of mercury (Hg) has been reported in different Mediterranean species, mainly collected in the southern coast of France.

Acarnidae (Porifera: Demospongiae: Poecilosclerida) from the Mexican Pacific Ocean with the description of six new species

open access: yesScientia Marina, 2013
The family Acarnidae is characterized by sponges with ectosomal diactinal spicules and choanosomal monactinal spicules. Microscleres include palmate isochelae, toxas and echinating acanthostyles.
