Morphological and molecular characters have identified a new family and genus of Verongiida in the Porifera: Demospongiae. The taxa are based on a new study of Dendrilla lacunosa Hentschel, 1912, a species that, using integrative taxonomy, has been

Sponges of the genus Aplysina Nardo, 1834 (Porifera, Demospongiae) can produce a large diversity of natural products of interest to industries such as the pharmaceutical trade. Here, we investigated the dynamics of population density, sponge size, and

Evolution and multi-functionality of the chitin system in sponges (Porifera) is currently a prime focus in modern experimental zoology including in phylogenetic studies of diverse poriferan taxa. Here, we present the first evidence of chitin in the skeleton
