While several other sponges can form such basal carbonate skeletons in addition to or in place of their siliceous spicules, only sponges from one of the four currently recognized sponge classes, the calcareous sponges (Class Calcarea), are capable of producing calcite spicules, which is a synapomorphy of this class .

Calcareous sponges have spicules made of magnesium calcite (MgCO3), or may lack spicules altogether. Homoscleromorpha. Members of the order Heteractinida (class Calcarea) are characterized by a calcareous "octactine" spicule type, which looks like a snowflake with six branches and two additional branches positioned at right angles in a second growing plane. While the vast majority of ancient Calcarea inhabited shallow water throughout their fossil record, modern species have been found across all depths. Calcareous sponge spicules largely behave as calcite single-crystals (example: triactines of Pericharax heteroraphis). Calcareous sponges have a poor fossil record because the calcitic spicules do not preserve well, or may be lost when sediments are altered. Sponge reefs are known also from the Mesozoic Era. A common feature is the supporting skeleton, made of calcareous, star shaped structures - or spicules. 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. The heteractinids are characterized by eight-rayed calcareous spicules, or derivative forms.They are known from the base of the Lower Cambrian. Sinauer Associates Inc. Publishers, Sunderland MA.

Fossil specimen of the sponge Astraeospongium meniscus from the Silurian Niagara Group of Perry County, Tennessee (PRI 76744). 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 ). Calcareous sponges occur mainly on the rocky bottoms of the continental shelves in temperate, shallow waters; they are usually dull in colour. A common feature is the supporting skeleton, made of calcareous, star shaped structures - or spicules. Reproduction may be both sexual and asexual, by budding. These all fall under the main category of porifera, the scientific name for sponges.
