Magallana
''Magallana'' is a genus of true oysters (family Ostreidae) containing some of the most important oysters used for food. Species in this genus have been moved from ''Crassostrea'' after it was found to be paraphyletic. Species Extant species are: Species only known from the fossil record: * ''Magallana ingens'' (Zittel, 1865) † Genetics The genome of ''Magallana gigas'' has been recently sequenced revealing an extensive set of genes that enable it to cope with environmental stresses.

Magallana Ingens
''Magallana'' is a genus of true oysters (family Ostreidae) containing some of the most important oysters used for food. Species in this genus have been moved from '' Crassostrea'' after it was found to be paraphyletic Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In co ....

Pacific Oyster
The Pacific oyster, Japanese oyster, or Miyagi oyster (''Magallana gigas'') is an oyster native to the Pacific coast of Asia. It has become an introduced species in North America, Australia, Europe, and New Zealand. Etymology The genus ''Magallana'' is named for the Portuguese explorer Ferdinand Magellan and its specific epithet ''gígās'' is from the Greek for "giant". It was placed in the genus ''Crassostrea'' until 2017; from the Latin (language), Latin ''crass'' meaning "thick", ''ostrea'' meaning "oyster". In 2017, the World Register of Marine Species, WoRMS, following the DNA-based opinion of Salvi ''et al.'', moved all pacific members of ''Crassostrea'' to ''Magallana''. Parts of the scientific community resist this change and continue to argue that ''Crassostrea gigas'' should be the proper name. They argue that Salvi's DNA sampling is incomplete, and that criteria other than the genetic sequence should have been considered. Description The shell of ''M. gigas'' varie ...

Magallana Sikamea
''Magallana sikamea'', also known as the Kumamoto oyster or colloquially the Kumie or Kumo, is a species of edible true oyster native to the northwestern Pacific Ocean. It has been introduced to many other locations to be farmed commercially for food. Taxonomy The Kumamoto oyster was described in 1928 by I. Amemiya. It was originally classified as a variation of the Pacific oyster, ''M. gigas''. It has also been placed in the genus '' Crassostrea'' before species residing in the Pacific were moved to ''Magallana''. Description Kumamoto oysters resemble most other oysters and are closely related to the Pacific oyster. It can be distinguished by its deeper left valve which has at least three radial ridges. Its right valve is flat but has grooves. From a lateral view, the shell appears triangular. It is fairly small in comparison to other species, reaching a maximum length of . The oyster is also a slow grower, taking three years to reach market size. The adductor muscle scar is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magallana Nippona
The Iwagaki oyster (''Magallana nippona''), is an oyster native to Japan. It was first described in 1934. Etymology The genus ''Magallana'' is named for the Portuguese explorer Ferdinand Magellan and its specific epithet nippona is for "Japanese". It was previously placed in the genus '' Crassostrea''; from the Latin ''crass'' meaning "thick", ''ostrea'' meaning "oyster", and ''Crassostrea nippona'' is considered by part of the scientific community to be the proper denomination as an accepted alternative in WoRMS The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive catalogue and list of names of marine organisms.
