Chlorurus Sordidus
''Chlorurus sordidus'', known commonly as the daisy parrotfish or bullethead parrotfish, is a species of marine fish in the family Scaridae. Description The initial phase has very variable colouration. The smaller fishes can be a uniform dark brown to light gray and they may or may not possess a light band surrounding a dark spot on the caudal peduncle. Larger specimens can show a series of irregular rows of small, light spots towards the tail or they may have the light band surrounding the dark spot on the caudal peduncle. The terminal phase, male, is also variable and may have a large tan area on the flanks or on its caudal peduncle. It has a rounded snout. ''Chlorurus sordidus'' is a medium size fish and can reach a maximum size of length. Distribution ''Chlorurus sordidus'' is widespread throughout the tropical waters of the Indo-Pacific region, Red Sea included. Habitat and biology Before going to sleep, ''Chlorurus sordidus'' secretes a mucus which surrounds the fis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oriental Studies
Oriental studies is the academic field that studies Near Eastern and Far Eastern societies and cultures, languages, peoples, history and archaeology. In recent years, the subject has often been turned into the newer terms of Middle Eastern studies and Asian studies. Traditional Oriental studies in Europe is today generally focused on the discipline of Islamic studies, and the study of China, especially traditional China, is often called Sinology. The study of East Asia in general, especially in the United States, is often called East Asian studies. The European study of the region formerly known as "the Orient" had primarily religious origins, which have remained an important motivation until recent times. That is partly since the Abrahamic religions in Europe (Christianity, Judaism, and Islam) originated in the Middle East and because of the rise of Islam in the 7th century. Consequently, there was much interest in the origin of those faiths and of Western culture in general. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploration
Exploration refers to the historical practice of discovering remote lands. It is studied by geographers and historians. Two major eras of exploration occurred in human history: one of convergence, and one of divergence. The first, covering most of ''Human, Homo sapiens'' history, saw humans Recent African origin of modern humans, moving out of Africa, settling in new lands, and developing distinct cultures in relative isolation. Early explorers settled in Europe and Asia; 14,000 years ago, some crossed the Settlement of the Americas, Ice Age land bridge from Siberia to Alaska, and moved southbound to settle in the Americas. For the most part, these cultures were ignorant of each other's existence. The second period of exploration, occurring over the last 10,000 years, saw increased cross-cultural exchange through trade and exploration, and marked a new era of cultural intermingling, and more recently, convergence. Early writings about exploration date back to the 4th millennium B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swedish People
Swedes ( sv, svenskar) are a North Germanic ethnic group native to the Nordic region, primarily their nation state of Sweden, who share a common ancestry, culture, history and language. They mostly inhabit Sweden and the other Nordic countries, in particular Finland where they are an officially recognized minority, with a substantial diaspora in other countries, especially the United States. Etymology The English term "Swede" has been attested in English since the late 16th century and is of Middle Dutch or Middle Low German origin. In Swedish, the term is ''svensk'', which is from the name of '' svear'' (or Swedes), the people who inhabited Svealand in eastern central Sweden, and were listed as ''Suiones'' in Tacitus' history '' Germania'' from the first century AD. The term is believed to have been derived from the Proto-Indo-European reflexive pronominal root, , as the Latin ''suus''. The word must have meant "one's own (tribesmen)".

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chlorurus Spilurus
''Chlorurus spilurus'', known commonly as the Pacific daisy parrotfish or Pacific bullethead parrotfish and in Hawaiian called uhu, is a species of marine fish in the family Scaridae. The Pacific daisy parrotfish is widespread throughout the tropical waters of the Pacific. Description The initial phase fish, which can be female or male, have a white beak, an overall dark reddish coloration with a white caudal peduncle and fin with a black patch. There is great variation in the coloration among the terminal males of this species. Their body is greenish with big scales outlined with purple-blue lines, three purple-blue stripes around the mouth, and an orange and a white patch on the cheek. Taxonomy ''Chlorurus spilurus'' was once synonymized with ''Chlorurus sordidus'', but recent study indicates that ''C. spilurus'' is distinct from Forsskal's species.Parenti, P. and J.E.

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protogynous Hermaphrodite
Sequential hermaphroditism (called dichogamy in botany) is a type of hermaphroditism that occurs in many fish, gastropods, and plants. Sequential hermaphroditism occurs when the individual changes its sex at some point in its life. In particular, a sequential hermaphrodite produces eggs (female gametes) and sperm (male gametes) at different stages in life. Species that can undergo these changes from one sex to another do so as a normal event within their reproductive cycle that is usually cued by either social structure or the achievement of a certain age or size. In animals, the different types of change are male to female (protandry or protandrous hermaphroditism), female to male (protogyny or protogynous hermaphroditism), bidirectional (serial or bidirectional hermaphroditism). Both protogynous and protandrous hermaphroditism allow the organism to switch between functional male and functional female. Bidirectional hermaphrodites have the capacity for sex change in either directi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
