Aquilonastra Conandae
''Aquilonastra conandae'' is a species of starfish from the family Asterinidae found near the Mascarene Islands in the Indian Ocean. It is known for its asexual reproduction and is fissiparous. It is a small starfish, discrete and camouflaged, and occurs in coral reefs in the surf zone of large waves. The species was described in 2006 by Australian marine biologists P. Mark O'Loughlin and Francis Winston Edric Rowe, and gets its name from Chantal Conand. Description It is a very small starfish, less than , with seven or eight short, rounded arms, often irregular in length. This is due to its potential of regeneration, but also to its ability to reproduce through fissiparity. The arms measure in length, and the starfish has multiple madreporites and a single spine on the interradial plates. Solitary papules are present on the top of the starfish. Spikes are present and are rough, granular, and crystalline, and are conical and prominent on the arms. It has an irregular patte ...

Hermaphrodite
In reproductive biology, a hermaphrodite () is an organism that has both kinds of reproductive organs and can produce both gametes associated with male and female sexes. Many Taxonomy (biology), taxonomic groups of animals (mostly invertebrates) do not have separate sexes. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. For example, the great majority of tunicata, tunicates, pulmonate molluscs, opisthobranch, earthworms, and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates. Most plants are also hermaphrodites. Animal species having different sexes, male and female, are called Gonochorism, gonochoric, which is the opposite of hermaphrodite. There are also species where hermaphrodites exist alongside males (called androdioecy) or alongside females (called gynodioecy), or all three exist in the same species ( ...

Mozambique Channel
The Mozambique Channel (french: Canal du Mozambique, mg, Lakandranon'i Mozambika, pt, Canal de Moçambique) is an arm of the Indian Ocean located between the Southeast African countries of Madagascar and Mozambique. The channel is about long and across at its narrowest point, and reaches a depth of about off the coast of Mozambique. A warm current, the Mozambique Current, flows in a southward direction in the channel, leading into the Agulhas Current off the east coast of Southern Africa. Extent The International Hydrographic Organization (IHO) defines the limits of the Mozambique Channel as follows: ::''On the North.'' A line from the estuary of the River Rovuma () to Ras Habu, the northernmost point of Ile Grande Comore, the northernmost of the Comore (Comoro) Islands, to Cap d'Ambre (Cape Amber), the northern extremity of Madagascar (). ::''On the East.'' The west coast of Madagascar. ::''On the South.'' A line from Cap Sainte-Marie, the southern extremity of Mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Europa Island
Europa Island (, ), in Malagasy Nosy Ampela is a low-lying tropical atoll in the Mozambique Channel, about a third of the way from southern Madagascar to southern Mozambique. The island had never been inhabited until 1820, when the French family ''Rosier'' moved to it. The island officially became a possession of France in 1897. The island, garrisoned by a detachment from Réunion, has a weather station and is visited by scientists. Though uninhabited now, it is part of the " Scattered Islands" of the French Southern and Antarctic Lands administrative region. Europa Island was the setting of "Search in the Deep", a 1968 episode of ''The Undersea World of Jacques Cousteau'', partly focusing on the breeding habits of the green sea turtle. Description Europa is in diameter, with a maximum altitude of , and has of coastline. It is surrounded by coral beaches and a fringing reef and encloses a mangrove lagoon of around and open to the sea on one side. There are no ports ...

Indo-Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. It does not include the temperate and polar regions of the Indian and Pacific oceans, nor the Tropical Eastern Pacific, along the Pacific coast of the Americas, which is also a distinct marine realm. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. The region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in al ...

Aquilonis
''Aquilonis'' (Latin "of the North Wind") is a classical and choral studio album by the Swedish trio Trio Mediæval recorded in June 2014 and released on the ECM New Series November that same year. Composition The album is named after a Swedish North Wind. On this album the trio sings Icelandic chant and Italian sacred songs, with performing custom arrangements from old Norwegian folk melodies. The trio also sings some 15th-century English carols, as well as contemporary works by Anders Jormin, William Brooks and Andrew Smith. It's the first time that the trio also plays instruments with their voice on a record. Reception James Manheim in his review for All Music says that "This certainly isn't an authentic performance of medieval music." but, he add that "In a way, it gets listeners closer than almost anybody else to the time when vertical sonorities in European music were new, and for those who have never heard it, it's time to begin."

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...
