Mitochondrial diversity of early-branching metazoa is revealed by the complete mt genome of a Haplosclerid Demosponge

, 2007
The first mitochondrial (mt) genomes of demosponges have recently been sequenced and appear to be markedly different from published eumetazoan mt genomes.

Insights into the reproduction of some Antarctic dendroceratid, poecilosclerid, and haplosclerid demosponges.

PLoS ONE, 2018
Sponges are a dominant element of the Antarctic benthic communities, posing both high species richness and large population densities. Despite their importance in Antarctic ecosystems, very little is known about their reproductive patterns and strategies.

Recycling resources: silica of diatom frustules as a source for spicule building in Antarctic siliceous demosponges

, 2020
Dissolved silicon (DSi) is biologically processed to produce siliceous skeletons by a variety of organisms including radiolarians, silicoflagellates, choanoflagellates, plants, diatoms and some animals. In the photic ocean, diatoms are dominant consumers
