A review of Norwegian streptaster-bearing Astrophorida (Porifera: Demospongiae: Tetractinellida), new records and a new species
We report and describe new material of streptaster-bearing Astrophorida sponges collected in Norway: Characella pachastrelloides, Pachastrella nodulosa sp. nov., Poecillastra compressa, Vulcanella cf. aberrans, Thenea abyssorum,Thenea levis, Thenea muricata and Thenea valdiviae.
