First Report on Chitin in a Non-Verongiid Marine Demosponge: The Mycale euplectellioides Case
Marine Drugs, 2018 Sponges (Porifera) are recognized as aquatic multicellular organisms which developed an effective biochemical pathway over millions of years of evolution to produce both biologically active secondary metabolites and biopolymer-based skeletal structures ...

Description of a new species of Membranobalanus (Crustacea, Cirripedia) from southern Australia [PDF]
ZooKeys, 2019 A new species of sponge-inhabiting barnacle, Membranobalanus porphyrophilus sp. nov., is described herein. This species can be distinguished from all other congeners by a combination of characters, in particular by the shapes of the tergum and scutum and
