Pterophyllum Leopoldi
''Pterophyllum leopoldi'', also referred to as the teardrop angelfish, Leopold's angelfish dwarf angelfish, or roman-nosed angelfish, is an angelfish species native to the Amazon River (between Manacapuru and Santarém), Essequibo River and Rupununi River. It is distinguished from other members of the genus ''Pterophyllum'' by the absence of a pre-dorsal notch, and by the presence of a black blotch at the dorsal insertion on the 4th vertical bar. The species is frequently misidentified as ''P. dumerilii'' when it is imported in the aquarium trade. ''P. leopoldi'' is the smallest of the angelfish species, reaching a length of SL and a height of SL, and the most aggressive. The specific name honours King Leopold III of Belgium, who sponsored the expedition to the Amazon Amazon most often refers to: * Amazons, a tribe of female warriors in Greek mythology * Amazon rainforest, a rainforest covering most of the Amazon basin * Amazon River, in South America * Amazon (company) ...

Freshwater Angelfish
''Pterophyllum'' is a small genus of freshwater fish from the family Cichlidae known to most aquarists as angelfish. All ''Pterophyllum'' species originate from the Amazon Basin, Orinoco Basin and various rivers in the Guiana Shield in tropical South America. The three species of ''Pterophyllum'' are unusually shaped for cichlids being greatly laterally compressed, with round bodies and elongated triangular dorsal and anal fins. This body shape allows them to hide among roots and plants, often on a vertical surface. Naturally occurring angelfish are frequently striped transversely, colouration which provides additional camouflage. Angelfish are ambush predators and prey on small fish and macroinvertebrates. All ''Pterophyllum'' species form monogamous pairs. Eggs are generally laid on a submerged log or a flattened leaf. As is the case for other cichlids, brood care is highly developed. ''Pterophyllum'' should not be confused with marine angelfish, perciform fish found on shall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amazon River
The Amazon River (, ; es, Río Amazonas, pt, Rio Amazonas) in South America is the largest river by discharge volume of water in the world, and the disputed longest river system in the world in comparison to the Nile. The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century as the Amazon basin's most distant source, until a 2014 study found it to be the headwaters of the Mantaro River on the Cordillera Rumi Cruz in Peru. The Mantaro and Apurímac rivers join, and with other tributaries form the Ucayali River, which in turn meets the Marañón River upstream of Iquitos, Peru, forming what countries other than Brazil consider to be the main stem of the Amazon. Brazilians call this section the Solimões River above its confluence with the Rio Negro forming what Brazilians call the Amazon at the Meeting of Waters ( pt, Encontro das Águas) at Manaus, the largest city on the river. The Amazon River has an average discharge of about – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Essequibo River
The Essequibo River (Spanish: ''Río Esequibo'' originally called by Alonso de Ojeda ''Río Dulce'') is the largest river in Guyana, and the largest river between the Orinoco and Amazon. Rising in the Acarai Mountains near the Brazil–Guyana border, the Essequibo flows to the north for through forest and savanna into the Atlantic Ocean. With a total drainage basin of and an average discharge of . Territory near the river is argued over by Venezuela and Guyana. Venezuela considers that the natural border according to the divortium aquarum that delimits the eastern margin of that country with the Cooperative Republic of Guyana is "by law", although due to the territorial dispute between the two countries for the sovereignty of Guayana Esequiba, it is "De facto administered and occupied for the most part by the former English colony of British Guiana, present-day Guyana.

Rupununi River
The Rupununi is a region in the south-west of Guyana, bordering the Brazilian Amazon. The Rupununi river, also known by the local indigenous peoples as ''Raponani'', flows through the Rupununi region. The name Rupununi originates from the word ''rapon'' in the Makushi language, in which it means the black-bellied whistling duck found along the river. Geography The Rupununi River is one of the main tributaries of the Essequibo River and is located in southern Guyana. The river originates in the Kanuku Mountains, which are located in the Upper Takutu-Essequibo region. The Rupununi River flows near the Guyana-Brazil border, and eventually leads into the Essequibo River. Throughout the flood season, the river shares a watershed with the Amazon. During the rainy season it is connected to the Takutu River by the flooded Pirara Creek, draining the vast swamps of the Parima or Amaku Lake. The region surrounding the Rupununi river is composed of mainly savannah, wetlands, forest, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Cichlid Room Companion
The Cichlid Room Companion (CRC), is a membership-based webpage dedicated to the fishes of the Cichlid family (''Cichlidae''). The site was launched in November 1997 and offers arguably the most comprehensive authoritative catalogue of cichlids in the web, which is illustrated with more than 20,000 photographs of fishes and 1,000 of habitats, as well as over 270 videos of cichlids and their habitats. It also “offers access to information about over 150 full genera and 900 full species profiles”, a discussion forum An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages. They differ from chat rooms in that messages are often longer than one line of text, and are at least tempora ..., as well as various articles about taxonomy, natural history, fish-keeping, field accounts, collecting expeditions and other cichlid related topics; mostly written by citizen scientists and people who specialize in cich ...

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] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

King Leopold III
Leopold III (3 November 1901 – 25 September 1983) was King of the Belgians from 23 February 1934 until his abdication on 16 July 1951. At the outbreak of World War II, Leopold tried to maintain Belgian neutrality, but after the German invasion in May 1940, he surrendered his country, earning him much hostility, both at home and abroad. Leopold's act was declared unconstitutional by Prime Minister Hubert Pierlot and his cabinet, who moved to London to form a government-in-exile, while Leopold and his family were placed under house arrest. In 1944, they were moved to Germany and then Austria, before being liberated by the Americans, but banned for some years from returning to Belgium, where his brother Prince Charles, Count of Flanders, had been declared regent. Leopold's eventual return to his homeland in 1950 nearly caused a civil war, and under pressure from the government, he abdicated in favour of his son Baudouin in July 1951. Leopold's first wife, Astrid of Sweden, was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
