This order is only known from Paleozoic fossils dating from the Early Cambrian to the end-Permian mass extinction (Picket, 2008). There is no epidermal epithelium. The skeleton of a sponge is formed from spicules which are made of silica (a glass-like material) or calcareous (calcium or calcium carbonate) materials, and spongin, a protein that supports the spicules. They are, by far, the sponge class with the highest diversity of spicule and body forms. , Ithaca, New York.

Hexactinellida or Triaxonida or Hyalospongiae—(Glass Sponge) 3. Select Page. Maximum diameter of specimen is approximately 8 cm. Kluwer Academic/Plenum Publishers: New York, NY (USA). Calcarean species are exclusively marine animals. II. 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. Calcareous sponges take a wide range of shapes, including irregular massive forms, vase-shaped bodies on a stalk or meshworks of thin tubes. Development of this project was supported by the National Science Foundation. The terms "gastrula" and "gastrulation" were coined by Ernst Haeckel, in his 1872 work "Biology of Calcareous Sponges". 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.

Some recent Antarctic expeditions have discovered a "sponge kingdom," where at least five Calcarea sponge species have been found at depths in excess of 4400 m. Highly simplified overview of Porifera phylogeny based in part on the hypothesis of relationships presented by Botting and Muir (2018). Early sponge evolution: A review and phylogenetic framework. Calcarea diversity. 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). Class Demospongia with a skeleton formed of siliaceous spicules and sponging fibres. 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 Reproduction may be both sexual and asexual, by budding. Calcarea Systematics The basal group of the Calcarea is the Heteractinida. 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.

An example is their fauna of calcareous sponges (Porifera: Calcarea), with only six species described up to date. This page uses Google Analytics. Global Diversity of Sponges (Porifera). Adult sponges are sessile animals that live attached to hard rocky surfaces, shells, or submerged objects. Some examples of sponges are: Sea Sponge,Tube Sponge,Vase Sponge, Yellow Sponge , Painted Tunicate Sponge, and the Bright Red Tree Sponge. Porifera  Examples of sponges. Clacareous sponges from abyssal and bathyal depths in the Weddell Sea, Antarctica. For example, in Antarctica, at depths of 100-200 m, 75 per cent of the benthic biomass are sponges.

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 take a wide range of shapes. Calcareous sponge, any of a class (Calcarea) of sponges characterized by skeletons composed entirely of calcium carbonate spicules (needlelike structures). 713 pp. They are called glass sponges; skeleton is of siliceous spicules which are triaxon with six rays. 0. 2012. See captions of individual images for attributions. Zoc. Calcareous sponges occur mainly on the rocky bottoms of the continental shelves in temperate, shallow waters; they are usually dull in colour.

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 . Examples: Sycon or Scypha, Grantia. calcareous sponge classification. In: Hooper J.N.A., Van Soest R.W.M., Willenz P. (eds) Systema Porifera. Pickett J., 2002. Brusca, R.C., and G.J. Specimen is from the collections of the Paleontological Research Institution, Ithaca, New York. That said, they have the most diversity of any other sponge class making classification difficult. The fauna of Porifera along the Norwegian coast is rich, representing about 260 species (Tendal, Brattegard & Rapp, 2001). Calcarea or Calcispongiae— (Calcareous Sponges) 2. A common feature is the supporting skeleton, made of calcareous, star shaped structures - or spicules. Calcareous sponges have a poor fossil record because the calcitic spicules do not preserve well, or may be lost when sediments are altered. 1-29. Demospongiae –– 4. These usually have three points, but some species have two or four pointed spicules. Demospongiae. These include, irregular massive forms, vase-shaped bodies on a stalk or meshworks of thin tubes (common feature that supports the skeleton are spicules). The heteractinids are characterized by eight-rayed calcareous spicules, or derivative forms.They are known from the base of the Lower Cambrian.
