The World Register of Marine Species is an over 90% complete open-access inventory of all
marine species names. Here we illustrate the scale of the problems with species names …

The most diverse and species-rich class of the phylum Porifera is Demospongiae. In recent
years, the systematics of this clade, which contains more than 7000 species, has developed …

Despite the fact that South East (SE) Asia is considered as a biodiversity hotspot, knowledge
of sessile invertebrates such as freshwater sponges (Porifera: Haplosclerida: Spongillina) in …

The combination of ocean warming and acidification as a result of increasing atmospheric
carbon dioxide (CO2) is considered to be a significant threat to calcifying organisms and …

Most marine sponges precipitate silicate skeletal elements, and it has been predicted that
they would be among the few “winners” among invertebrates in an acidifying, high-CO 2 …

Temperate reefs, built by multilayers of encrusting algae accumulated during hundreds to
thousands of years, represent one of the most important habitats of the Mediterranean Sea …

Sponge classification has long been based mainly on morphocladistic analyses but is now
being greatly challenged by more than 12 years of accumulated analyses of molecular data …

Background Demosponges are challenging for phylogenetic systematics because of their
plastic and relatively simple morphologies and many deep divergences between major …

Eight cyclic peroxide norterpenoids, compounds 1–8, have been isolated and characterized
from the Red Sea sponge Diacarnus erythraeanus, including two new norsesterterpene …

The family Oscarellidae is one of the two families in the class Homoscleromorpha (phylum
Porifera) and is characterized by the absence of a skeleton and the presence of a specific …
