The order Axinellida (Porifera: Demospongiae) in California [PDF]
Zootaxa, 2022 Sponges are common and diverse in California, but they have received little study in the region, and the identities of many common species remain unclear. Here we combine fresh collections and museum vouchers to revise the order Axinellida for California.

Widespread Distribution of Poribacteria in Demospongiae [PDF]
Applied and Environmental Microbiology, 2009 ABSTRACT Poribacteria were found in nine sponge species belonging to six orders of Porifera from three oceans. Phylogenetic analysis revealed four distinct poribacterial clades, which contained organisms obtained from several different geographic regions, indicating that the distribution of poribacteria is cosmopolitan.

Proposal for a revised classification of the Demospongiae (Porifera) [PDF]
Frontiers in Zoology, 2015 Demospongiae 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 classification, essentially based on morphological data. Since then, an increasing number of molecular phylogenetic studies

Chemotaxonomy of Agelas (Porifera: Demospongiae) [PDF]
Biochemical Systematics and Ecology, 1992 The secondary metabolite content of four different species of Agelas (Porifera) from the West Indies has been studied. All the compounds isolated are already known metabolites whose identification was confirmed by comparison of their spectral properties with those reported in the literature.

Dosilia (Porifera, Demospongiae) redefined [PDF]
Iheringia. Série Zoologia, 2010 Dosilia plumosa (Carter, 1849), type species of the genus, and D. brouni (Kirkpatrick, 1906), with distribution respectively in the Oriental and Ethiopic regions, are revised based on a SEM analysis of spicules, gemmules and skeletal structure. The lectotype here designated for D.
