Luffariella is a genus of sea sponges in the family Thorectidae. [1]
One of its species is one of the few organisms that synthesizes derivatives of cyclopentanepentol. [2] [3] [4]
The following species are recognised in the genus Luffariella:
Sponges, the members of the phylum Porifera, are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include greater than 90% of all species of sponges with nearly 8,800 species worldwide. 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.
Halichondria is a genus of sea sponges belonging to the family Halichondriidae. These are massive, amorphous sponges with clearly separated inner and outer skeletons consisting of bundles of spicules arranged in a seemingly random pattern.
Spongia is a genus of marine sponges in the family Spongiidae, originally described by Carl Linnaeus in 1759, containing more than 60 species. Some species, including Spongia officinalis, are used as cleaning tools, but have mostly been replaced in that use by synthetic or plant material.
Axinella is a genus of sponges in the family Axinellidae first described in 1862 by Eduard Oscar Schmidt. Species of Axinella occur in the Indian and Pacific Oceans. Most of these sponges are smaller than 20 cm, and have a yellow or orange colour.
Ageliferin is a chemical compound produced by some sponges. It was first isolated from Caribbean and then Okinawan marine sponges in the genus Agelas. It often co-exists with the related compound sceptrin and other similar compounds. It has antibacterial properties and can cause biofilms to dissolve.
Tethya is a genus of sea sponges belonging to the family Tethyidae. Members of this genus all have a spherical body form and some are known to be able to move at speeds of between 1 and 4 mm per day.
Ircinia is a genus of sea sponges in the family Irciniidae.
Plakoridine A is an alkaloid isolated from the marine sponge Plakortis sp. There are three plakoridines known, named plakoridine A, B, and C.
Dysidea arenaria is a species of marine sponge (poriferan) found in the Pacific Ocean. It is a member of the order Dictyoceratida, one of two sponge orders that make up the keratose or "horny" sponges in which a mineral skeleton is absent and a skeleton of organic fibers is present instead.
Thorectidae is a family of sea sponges in the order Dictyoceratida.
Swinholides are dimeric 42 carbon-ring polyketides that exhibit a 2-fold axis of symmetry. Found mostly in the marine sponge Theonella, swinholides encompass cytotoxic and antifungal activities via disruption of the actin skeleton. Swinholides were first described in 1985 and the structure and stereochemistry were updated in 1989 and 1990, respectively. Thirteen swinholides have been described in the literature, including close structural compounds such as misakinolides/bistheonellides, ankaraholides, and hurgholide A It is suspected that symbiotic microbes that inhabit the sponges rather than the sponges themselves produce swinholides since the highest concentration of swinholides are found in the unicellular bacterial fraction of sponges and not in the sponge fraction or cyanobacteria fraction that also inhabit the sponges.
1,2,3,4,5-Cyclopentanepentol, also named cyclopentane-1,2,3,4,5-pentol or 1,2,3,4,5-pentahydroxycyclopentane is a chemical compound with formula C
5H
10O
5 or (–CHOH–)
5, whose molecule consists of a ring of five carbon atoms, each connected to one hydrogen and one hydroxyl group. The unqualified term "cyclopentanepentol" usually refers to this compound. There are four distinct stereoisomers with this same structure.
Cymbastela coralliophila is a species of marine sponge in the family Axinellidae.
Dysidea is a genus of sponges belonging to the family Dysideidae.
Suberea is a genus of sponges belonging to the family Aplysinellidae.
Latrunculia is a genus of demosponges. It is well known for the diverse array of chemical compounds found in its species, including the latrunculins, which are named after this genus. Many of these are medically important, including anti-cancer compounds such as discorhabdins.
Euryspongia is a genus of sponges belonging to the family Dysideidae.
