Calcareous sponge, any of a class (Calcarea) of sponges characterized by skeletons composed entirely of calcium carbonate spicules (needlelike structures). Hexactinellida or Triaxonida or Hyalospongiae—(Glass Sponge) 3. 0. An example is their fauna of calcareous sponges (Porifera: Calcarea), with only six species described up to date. Calcareous sponges occur mainly on the rocky bottoms of the continental shelves in temperate, shallow waters; they are usually dull in colour. Fossil Invertebrates. 936 pp. Calcareous sponges have a poor fossil record because the calcitic spicules do not preserve well, or may be lost when sediments are altered. See captions of individual images for attributions. Porifera: The Sponges Steven Sadro Found at all depths and latitudes, sponges are among the most ubiquitous of marine organisms. –– 2. They are called glass sponges; skeleton is of siliceous spicules which are triaxon with six rays.

One of the species with wide range distribution (Caribbean-Brazil), Ernstia rocasensis , presented plasticity in their skeleton. All of the following sponges are found within the coral cap region of the sanctuary (0-130 ft, 0-40m deep). 2. 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. Examples: calcareous sponges; Ecology: marine; Key features of group: ascon, sycon and leucon body forms, Mg-calcite unfused, monoaxon, diactine, triactine, tetracline, or polyactine spicules; Diversity: ~786 living sp.

"The Marine Flora & Fauna of Norway", by KÃ¥re Telnes. A common feature is the supporting skeleton, made of calcareous, star shaped structures - or spicules. (Eds.) In some the spicules are fused to form a lattice-like skeleton. 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 . The three classes are: 1. Maximum diameter of specimen is approximately 8 cm.

These usually have three points, but some species have two or four pointed spicules. A unique characteristic discovered in living members of class Calcarea is vivipary (Hooper and van Soest, 2002). Above Image: Kunstformen der Natur (1904), plate 5: Calcispongiae by Ernst Haekel (Public Domain). As a result, calcareous sponges are quite brittle to touch. This page uses Google Analytics. Class Calcarea includes sponges that are small in size and less colorful than other sponge classes. Some examples of sponges are: Sea Sponge,Tube Sponge,Vase Sponge, Yellow Sponge , Painted Tunicate Sponge, and the Bright Red Tree Sponge. Class. Hooper, J.N.A. The Caribbean staghorn sponge, C. cuspidifera (Lamarck) (previously as Spheciospongia) (Hadromerida), is a good example. 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. Bead-like calcareous sponges, along with skeletal algae and inorganic cements, constructed massive reefs in Permian time. Fossil record: Cambrian to Recent The Digital Atlas of Ancient Life project is managed by the Paleontological Research Institution, Ithaca, New York. Calcareous sponge, any of a class (Calcarea) of sponges characterized by skeletons composed entirely of calcium carbonate spicules (needlelike structures). Botting, J.P, and Muir, L.A. 2018. 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. Calcareous sponges take a wide range of shapes, including irregular massive forms, vase-shaped bodies on a stalk or meshworks of thin tubes.

Calcareous sponges occur mainly on the rocky bottoms of the continental shelves in temperate, shallow waters; they are usually dull in colour. These include, irregular massive forms, vase-shaped bodies on a stalk or meshworks of thin tubes (common feature that supports the skeleton are spicules). 2011. ... Lime is, in fact, absorbed to an enormous extent by fishes, molluscs, crustacea, calcareous algae and sponges, starfishes, sea-urchins and feather stars, many polyzoa and a multitude of protozoa (mainly the foraminifera). The heteractinids are characterized by eight-rayed calcareous spicules, or derivative forms.They are known from the base of the Lower Cambrian.
