ADVERTISEMENTS: The following points highlight the three main classes of Phylum Porifera. –– 4. Calcareous sponges comprise approximately 675 accepted extant species ; therefore, this class is considerably less diverse than for example, the most species-rich class, Demospongiae, which contains approximately 7.000 recognized species.

Reproduction may be both sexual and asexual, by budding. The study of Calcarea from the Norwegian coast started with collections made by Haeckel in 1869 on the Norwegian west coast, and later he reported 14 species from Norway (Haeckel, 1872). A common feature is the supporting skeleton, made of calcareous, star shaped structures - or spicules.

After examining about 1000 specimens, and tracing the development of the soft tissues and skeleton at the growing edges., I became convinced that Merlia was, beyond doubt, a sponge with a siliceous and calcareous skeleton (5).

However, despite the great number of species, very few taxonomic works based on Norwegian sponges have been published. The Symp. Being viviparous means they brood their young inside their body wall instead of broadcasting both eggs and sperm into the vast ocean to then form larvae and settle on their own.
