Haplosporidium Pinnae
''Haplosporidium'' is a genus under order Haplosporida. WoRMS (2021). Haplosporidium Lühe, 1900. Accessed at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=391857 on 2021-12-28 They are a group of eukaryotes that are parasites of marine invertebrates, causing multiple disease which has high mortality to its host, including the notorious disease MSX, which caused massive oyster mortalities in Delaware Bay in 1957 and two years later in Chesapeake Bay. There are four genus under order haplosporida, according to thHand book of the Protists(2017) The principal characteristics of this genus are spores with an apical-hinged operculum and a variety of extensions externally (tails, filaments, extensions, wrapping, folds, and epispore extensions) formed by the same material of the spore wall. The number of ornaments is variable according to the different species. The internal uninucleated endosporoplasm contains a spherulosome (structure formerly designated by the name “sphe ...

Eukaryota
Eukaryotes () are organisms whose Cell (biology), cells have a cell nucleus, nucleus. All animals, plants, fungi, and many unicellular organisms, are Eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the Three-domain system, three domains of life. Bacteria and Archaea (both prokaryotes) make up the other two domains. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the Asgard (archaea), Asgard archaea. This implies that there are only Two-domain system, two domains of life, Bacteria and Archaea, with eukaryotes incorporated among archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass (ecology), biomass is estimated to be about equal to that of prokaryotes. Eukaryotes emerged approximately 2.3–1.8 billion years ago, during the Proterozoic eon, likely as Flagellated cell, flagellated phagotrophs. The ...

Gravez (Eds.), ''Les Especes Marines a Proteger en Mediterranee'' (pp. 169–178). Marseille, France: GIS Posidonie publ. It produces a rare manganese-containing porphyrin protein known as pinnaglobin. Description The bivalve shell is usually long, but can reach . Its shape differs depending on the region it inhabits. Like all pen shells, it is relatively fragile to pollution and shell damage. It attaches itself to rocks using a strong byssus composed of many silk-like threads which used to be made into cloth. The animal secretes these fibres from its byssus gland; they consist o ...

Eastern Oyster
The eastern oyster (''Crassostrea virginica'')—also called the Atlantic oyster, American oyster, or East Coast oyster—is a species of true oyster native to eastern North and South America. Other names in local or culinary use include the Wellfleet oyster, Virginia oyster, Malpeque oyster, Blue Point oyster, Chesapeake Bay oyster, and Apalachicola oyster. ''C. virginica'' ranges from northern New Brunswick through parts of the West Indies and south to Brazil. It is farmed in all of the Maritime provinces of Canada and all Eastern Seaboard and Gulf states of the United States, as well as Puget Sound, Washington, where it is known as the Totten Inlet Virginica. It was introduced to the Hawaiian Islands in the nineteenth century and is common in Pearl Harbor. The eastern oyster is an important commercial species. Its distribution has been affected by habitat change; less than 1% of the population present when the first European colonists arrived is thought to remain in the Ch ...

Haplosporidium Nelsoni
''Haplosporidium nelsoni'' is a pathogen of oysters that originally caused oyster populations to experience high mortality rates in the 1950s, and still is quite prevalent today. The disease caused by ''H. nelsoni'' is also known as MSX (multinucleated unknown or multinuclear sphere X). MSX is thought to have been introduced by experimental transfers of the Pacific oyster (''Crassostrea gigas''), which is resistant to this disease. MSX was first described in 1957, when it caused serious mortalities in Delaware Bay. Through extensive studies, an estimated 50% of eastern oyster (''C. virginica'') mortalities in lower Delaware Bay since the 1960s could be attributed to MSX infections, a devastating loss to the area. Mortalities are usually highest in the summer, and also increase in higher-salinity waters. MSX reduces the feeding rates of infected oysters, leading to a reduced amount of stored carbohydrates. The reduction in stored carbohydrates inhibits normal gametogenesis in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Ormer
The green ormer (''Haliotis tuberculata'') is a northeast Atlantic and Mediterranean species of sea snail, a coastal marine gastropod mollusc in the family Haliotidae, the abalones or ormer snails. The flesh of the green ormer is prized as a delicacy, and this has led to a decline in its population in some areas. Taxonomy ''Haliotis barbouri'' Foster, 1946 is a synonym for ''Haliotis varia''. According to the World Register of Marine Species (WoRMS) the following subspecies are recognized: * ''Haliotis tuberculata coccinea'' Reeve, 1846 (synonyms: ''Haliotis canariensis'' F. Nordsieck, 1975; ''Haliotis coccinea'' Reeve, 1846; ''Haliotis zealandica'' Reeve, 1846) * ''Haliotis tuberculata fernandesi'' Owen, Grace, & Afonso * ''Haliotis tuberculata marmorata'' Linnaeus, 1758 * ''Haliotis tuberculata tuberculata'' Linnaeus, 1758 (synonyms: ''Haliotis aquatilis'' Reeve, 1846; ''Haliotis incisa'' Reeve, 1846; ''Haliotis janus'' Reeve, 1846; ''Haliotis japonica'' Reeve, 1846; ''Hali ...
