Reproduction may be both sexual and asexual, by budding. Original caption: "A. Calcareous sponges are small, usually only a few inches high, and are generally dull in appearance, although several species are brightly colored. It is common in shallow reef sands but only the branching inhalant fistules are seen protruding from the bottom, whereas most of the sponge body is buried and was only discovered after extensive digging ( Rützler, 1997; Rützler and Hooper, 2000 ). There is no epidermal epithelium. In the oscular re-gion, the sponge wall is thin. 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). An example is their fauna of calcareous sponges (Porifera: Calcarea), with only six species described up to date. Zoc. 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. With the advent of modern laboratory and field techniques (e.g., electron microscopy, histochemistry, the development of molecular biology and biochemistry, and the use of SCUBA for collection purposes) our The fauna of Porifera along the Norwegian coast is rich, representing about 260 species (Tendal, Brattegard & Rapp, 2001). These include, irregular massive forms, vase-shaped bodies on a stalk or meshworks of thin tubes (common feature that supports the skeleton are spicules).
