Polycheira Rufescens

	Polycheira Rufescens ''Polycheira'' is a genus of holothurians (sea cucumbers) found in tropical Indo-Pacific. A curious pattern of reproduction has been found in ''Polycheira rufescens'' where specimens change their sex from male to female and from female to male in a reproductive season Systematics ''Polycheira'' appear to be closely related to the genus ''Chiridota'' (both belong to the subfamily Chiridotinae). The type species of the genus is ''Polycheira rufescens'' (Brandt, 1835). The following species are recognised in the genus ''Polycheira'': ''Polycheira echinata'' Heding, 1928 ''Polycheira rufescens ''Polycheira'' is a genus of holothurians (sea cucumbers) found in tropical Indo-Pacific.

	Holothuria ''Holothuria'' is the type genus of the marine animal family Holothuriidae, part of the class Holothuroidea, commonly known as sea cucumbers. Members of the genus are found in coastal waters in tropical and temperate regions. They are soft bodied, limbless invertebrates that dwell on the ocean floor and are usually detritivore. They resemble a cucumber in form. The genus contains some species that are harvested and sold as food. Species The following species are recognised in the genus ''Holothuria'': * Subgenus ''Acanthotrapeza'' '' Holothuria coluber'' '' Holothuria kubaryi'' ''Holothuria pyxis'' ''Holothuria tripilata'' * Subgenus ''Cystipus'' ''Holothuria casoae'' ''Holothuria cubana'' ''Holothuria dura'' ''Holothuria hartmeyeri'' ''Holothuria inhabilis'' ''Holothuria jousseaumei'' ''Holothuria mammosa'' ''Holothuria occidentalis'' '' Holothuria pseudofossor'' '' Holothuria rigida'' ''Holothuria sucosa ...

picture info	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 ...

picture info	Type Species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

picture info	Holothuroidea Genera Sea cucumbers are echinoderms from the class Holothuroidea (). They are marine animals with a leathery skin and an elongated body containing a single, branched gonad. Sea cucumbers are found on the sea floor worldwide. The number of holothurian () species worldwide is about 1,717, with the greatest number being in the Asia-Pacific region. Many of these are gathered for human consumption and some species are cultivated in aquaculture systems. The harvested product is variously referred to as '' trepang'', ''namako'', ''bêche-de-mer'', or ''balate''. Sea cucumbers serve a useful role in the marine ecosystem as they help recycle nutrients, breaking down detritus and other organic matter, after which bacteria can continue the decomposition process. Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue. In some species these can sometimes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
