Aiteng Mysticus
''Aiteng mysticus'' is a species of sea slug in the family Aitengidae, found around Hisamatsu, Miyako-jima, Okinawa, Japan. Morphologically it clearly belongs to the Aitengidae, but it shows differences to ''Aiteng ater'' at genus or species level. Its affinity to ''Aiteng ater'' is confirmed by comparison of the mitochondrial 16S rRNA 16S ribosomal RNA (or 16Svedberg, S rRNA) is the RNA component of the 30S subunit of a prokaryotic ribosome (SSU rRNA). It binds to the Shine-Dalgarno sequence and provides most of the SSU structure. The genes coding for it are referred to as ... sequences.

Philippe Bouchet
Philippe Bouchet (born 1953) is a French biologist whose primary scientific fields of study are malacology (the study of molluscs) and taxonomy. He works at the Muséum National d'Histoire Naturelle in Paris. He is also a Commissioner of the International Commission on Zoological Nomenclature. Bouchet published Taxonomy of the Gastropoda with the malacologist Jean-Pierre Rocroi in 2005, which laid out a new taxonomy of Gastropod molluscs. He has named over 500 new taxa of mollusks, with numerous others being named in his honor. Professional achievements Bouchet is a senior professor at the Muséum National d'Histoire Naturelle in Paris and is head of the Malacology laboratory and the Taxonomy Collections Unit there. He is also one of the Commissioners of the International Commission on Zoological Nomenclature and has been a member of the ICZN since 1990. Philippe Bouchet is co-editor of several volumes in the Tropical Deep-Sea Benthos series. In 2005, Bouchet was the senio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Slug
Sea slug is a common name for some Marine biology, marine invertebrates with varying levels of resemblance to terrestrial Slug, slugs. Most creatures known as sea slugs are gastropods, i.e. they are Sea snail, sea snails (marine gastropod mollusks) that, over evolutionary time, have either entirely lost their shells or have seemingly lost their shells due to having a significantly reduced or internal shell. The name "sea slug" is often applied to Nudibranch, nudibranchs and a paraphyletic set of other marine gastropods without apparent Gastropod shell, shells. Sea slugs have an enormous variation in body shape, color, and size. Most are partially translucent. The often bright colors of Coral reef, reef-dwelling species imply that these animals are under constant threat of predators. Still, the color can warn other animals of the sea slug's toxic stinging cells (nematocysts) or offensive taste. Like all Gastropod, gastropods, they have small, razor-sharp teeth called Radula, rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aitengidae
''Aiteng'' is a genus comprising three species of sea slug, ''A. ater'' and ''A. mysticus'' being found in intertidal zones while ''A. marefugitus'' is fully terrestrial. ''Aiteng'' is the only genus in the family Aitengidae. The name of a biological genus, generic name ''Aiteng'' is derived from the name of a black puppet Ai Theng, which is one of the shadow play (Nang drama, Nang yai) puppets in southern Thailand. Taxonomy Swennen & Buatip (2009) tentatively classified Aitengidae within the Sacoglossa, but they noted that some characteristics of the Nervous system of gastropods, nervous system are similar to those of the Cephalaspidea and Acochlidioidea (mentioned as Acochlidea). Aitengidae clusters within the Hedylopsacea as sister group to Pseudunelidae and Acochlidiidae or basal within Hedylopsacea. Philippe Bouchet (2010) classified Aitengidae within the superfamily Hedylopsoidea. Species Species in the genus ''Aiteng'' include: * ''Aiteng ater'' Swennen & Buatip, 2009 * ' ...

Miyako-jima
is the largest and the most populous island among the Miyako Islands of Okinawa Prefecture, Japan. Miyako Island is administered as part of the City of Miyako Island, which includes not only Miyako Island, but also five other islands. Geography Miyako Island lies approximately southwest of Okinawa Island. With an area of , Miyako is the fourth-largest island in Okinawa Prefecture. The island is triangular in shape and is composed of limestone. Miyako Island is subject to drought and is frequently struck by typhoons. Miyako Island is well known for its beauty, particularly the , a nationally designated Place of Scenic Beauty at the southeasternmost point of Miyako Island. It is considered by many as one of the most beautiful spots in Japan. Other notable locations include Yonaha Maehama beach, Sunayama beach, Painagama Beach and the sights on Irabu-jima.

Okinawa Prefecture
is the southernmost and westernmost prefecture of Japan. It consists of three main island groups—the Okinawa Islands, the Sakishima Islands, and the Daitō Islands—spread across a maritime zone approximately 1,000 kilometers east to west and 400 kilometers north to south. Despite a modest land area of 2,281 km² (880 sq mi), Okinawa’s territorial extent over surrounding seas makes its total area nearly half the combined size of Honshu, Shikoku, and Kyushu. Of its 160 Island, islands, 49 are inhabited. The largest and most populous island is Okinawa Island, which hosts the capital city, Naha, as well as major urban centers such as Okinawa (city), Okinawa, Uruma, and Urasoe, Okinawa, Urasoe. The prefecture has a subtropical climate, characterized by warm temperatures and high rainfall throughout the year.

MT-RNR2
Mitochondrially encoded 16S RNA (often abbreviated as ''16S'') is the mitochondrial large subunit ribosomal RNA that in humans is encoded by the MT-RNR2 gene. The MT-RNR2 gene also encodes the Humanin polypeptide that has been the target of Alzheimer's disease research. The 16S rRNA is the mitochondrial homologue of the prokaryotic 23S and eukaryotic nuclear 28S ribosomal RNAs. See also * Mitochondrial DNA * Humanin Humanin is a micropeptide encoded in the mitochondrial genome by the 16S ribosomal RNA gene, MT-RNR2. Its structure contains a three-turn α-helix, and no symmetry. In ''in vitro'' and animal models, it appears to have cytoprotective effects. ...
