Clionaidae
Clionaidae is a family of demosponges which are found worldwide. This family is known for parasitically boring holes in calcareous material such as mollusc shells and corals, using both chemical and mechanical processes.Brusca, R.C. & Brusca, G.J. 2002.

Demosponge
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite. They are predominantly leuconoid in structure. Their "skeletons" are made of spicules consisting of fibers of the protein spongin, the mineral silica, or both. Where spicules of silica are present, they have a different shape from those in the otherwise similar glass sponges. Some species, in particular from the Antarctic, obtain the silica for spicule building from the ingestion of siliceous diatoms. The many diverse orders in this class include all of the large sponges. Most are marine dwellers, but one order ( Spongillida) live in freshwater environments. Some species are brightly colored, with great variety in body shape; the largest species are ove ...

Acanthochaetetidae is a family of sponges belonging to the order Clionaida Clionaida is an order of demosponges in the subclass Heteroscleromorpha Heteroscleromorpha is a subclass of demosponges within the phylum In biology, a phylum (; plural: phyla) is a level of classification or taxonomic rank below kingdo .... It is largely extinct, but contains two extant genera, each of which are represented by single extant species. Description This family contains sclerosponges (corraline sponges) with a massive calcareous skeleton. This skeleton attaches individuals to their substrate. Living tissue coats the outermost layer of the basal skeleton. The megascleres include tylostyles (pointed at one end and a knob at the other). They are common and point outwards. The microscleres are relatively large streptasters (modified aster in which the rays radiate from an axis instead of meeting at a common center). The siliceous spicules suggest close ties to '' Spirastrella'' and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...
