Parachromis Friedrichsthalii
''Parachromis friedrichsthalii'', the Yellowjacket cichlid, is a species of cichlid native to Central America where it is found along the Atlantic Slope in Mexico, Belize, Honduras and Guatemala. This species grows to a length of SL. This species is popular with anglers as a gamefish and can also be found in the aquarium trade. The specific name honours the Austrian explorer, botanist and archaeologist Emanuel von Friedrichsthal (1809-1842), who sent many specimens to Vienna from Central America, including the type of this fish. ''P. friedrichsthalii'' has an unusual hunting mechanism. The species has been observed to lie immobile near the bottom, feigning death. When smaller fish approach and attempt to pick at the dead fish, ''P. friedrichsthalii'' ambush the smaller fish. Similar behaviour has also been observed in some species of Lake Malawi cichlids, particularly from the genus ''Nimbochromis ''Nimbochromis'' is a small genus of haplochromine cichlids mostly endemi ...

Johann Jakob Heckel
Johann Jakob Heckel (23 January 1790 – 1 March 1857) was an Austrian taxidermist, zoologist, and ichthyologist from Mannheim in the Electoral Palatinate. Life Though not a formally trained biologist, he worked his way up through the ranks to eventually become the director of the Fish Collection at the Naturhistorisches Museum in Vienna. For the most part, he was not a traveler or explorer like many of the scientists of the time, he remained in Vienna, where he studied and catalogued specimens sent to him from the field. Among those who brought specimens to him were Karl Alexander Hügel, Joseph Russegger and Theodor Kotschy — involving collection activities in Kashmir, the Middle East and northeastern Africa that greatly enriched the Vienna museum. Fish were his specialty and he worked with many of the greatest ichthyologists of his time including Cuvier, Valenciennes, Bonaparte, Müller, and Troschel.

Emanuel Von Friedrichsthal
Emanuel von Friedrichsthal (January 12, 1809 – March 3, 1842) was an Austrian traveler, daguerreotypist, botanist, and amateur archaeologist, who traveled through the Balkans and in Central America and documented his findings. Biography Von Friedrichsthal was born in Uhřice in the Austrian Empire (present-day Czech Republic). He was educated in Vienna at the Theresian Military Academy and entered Austrian government service, but soon left to pursue scientific travels. He traveled through Rumelia in the 1830s, publishing his findings in two books: ''Reise in die südlichen Theile von Griechenland'' (''Journey to the Southern Parts of Greece'', 1838) and ''Serbiens Neuzeit in geschichtlicher, politischer, topographischer, statistischer und naturhistorischer Hinsicht'' (''Modern Serbia in Historical, Political, Topographical, Statistical, and Natural-Historical Respects'', 1840). These publications acquired for him in particular a reputation in botany for their descriptions of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parachromis
''Parachromis'' is a genus of cichlids native to Central America. Some species occur in Lake Nicaragua and Lake Managua. All species are predatory and relatively large for cichlids. Species There are currently five recognized species in this genus: * ''Parachromis dovii'' ( Günther, 1864) (Wolf cichlid, Guapote) * ''Parachromis friedrichsthalii'' ( Heckel, 1840) (Yellowjacket cichlid) * ''Parachromis loisellei'' ( W. A. Bussing, 1989) * ''Parachromis managuensis'' ( Günther, 1867) (Jaguar cichlid, Jaguar guapote) * ''Parachromis motaguensis'' ( Günther, 1867) (False yellowjacket cichlid) Confusingly, a review in 2018 of the type specimen of ''P. friedrichsthalii'' showed that this actually is the species that commonly has been referred to as ''P. loisellei''. As a result, ''P. loisellei'' becomes a junior synonym The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name tha ...

Parachromis Motaguensis
''Parachromis motaguensis'', the False yellowjacket cichlid, is a species of cichlid native to Guatemala and Honduras in Central America. This species grows to a length of TL. This species is farmed. Aquarium care Unlike its close relative the Parachromis managuensis, commonly known and traded as the jaguar cichlid, the motaguensis isn't as commonly encountered in the aquarium trade. Although their visual appearance is very similar, the motaguensis (traded by many names, including Red tiger, Red dragon cichlid) displays an array of bright red dots, (hence the variants of the common name), which run along the flanks to the base of the caudal fin. An impressive array of this colouration is made distinct on the gills of this fish where such colour is highly pronounced. The female of this species is even more brilliantly coloured, with a deep shades of red and oranges much more prominent than the males colour. This colour is enhanced further during the breeding Breeding is se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parachromis Managuensis
''Parachromis managuensis'' is a large species of cichlid native to freshwater habitats in Central America, where it is found from Honduras to Costa Rica. The binomial name refers to Lake Managua in Nicaragua, from which the holotype was obtained. It is a food fish and is also found in the aquarium trade where it is variously known as the jaguar cichlid, managuense cichlid, managua cichlid, guapote tigre, Aztec cichlid, spotted guapote and jaguar guapote. In Costa Rica it is known as the ''guapote tigre''. Description ''P. managuensis'' is a robust fish with a silvery or golden-green to purple colour, with a darker moss green shade at the dorsum. The sides show a purple iridescence and the belly is whitish or yellowish. A series of several large black dots then run horizontally along the lateral line area. The fins are often a dark to black colouration, especially when in spawning colouration. The most distinguished feature is a black stripe than run from the eye to the opercular ...

Nimbochromis
''Nimbochromis'' is a small genus of haplochromine cichlids mostly endemic to Lake Malawi in East Africa. They are known as sleeper cichlids or ''kaligono'' ("sleepers" in Chichewa) due to their unique hunting behaviour. These piscivorous species are often seen lying motionless on the lake bottom near rocks where mbuna live, even adopting an unusual sideways position rarely seen in living fish. If smaller fishes approach, the ''Nimbochromis'' will "wake up" and try to seize them. Their coloration has an irregular dark cloudy pattern on lighter background; for one thing, this provides camouflage, but it is also suspected that it is – at least in some – evolving into aggressive mimicry (apparent death) by imitating a rotting fish carcass and thus luring scavengers to their demise. Species There are currently five recognized species in this genus: * '' Nimbochromis fuscotaeniatus'' (Regan, 1922) (Spothead Hap, Fuscotaeniatus Hap) * '' Nimbochromis linni'' ( W. E. Burges ...

Lake Malawi
Lake Malawi, also known as Lake Nyasa in Tanzania and Lago Niassa in Mozambique, is an African Great Lake and the southernmost lake in the East African Rift system, located between Malawi, Mozambique and Tanzania. It is the fifth largest fresh water lake in the world by volume, the ninth largest lake in the world by area—and the third largest and second deepest lake in Africa. Lake Malawi is home to more species of fish than any other lake in the world, including at least 700 species of cichlids.Turner, Seehausen, Knight, Allender, and Robinson (2001). "How many species of cichlid fishes are there in African lakes?" ''Molecular Ecology'' 10: 793–806.

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 ...

Zoological Specimen
A zoological specimen is an animal or part of an animal preserved for scientific use. Various uses are: to verify the identity of a (species), to allow study, increase public knowledge of zoology. Zoological specimens are extremely diverse. Examples are bird and mammal study skins, mounted specimens, skeletal material, casts, pinned insects, dried material, animals preserved in liquid preservatives, and microscope slides. Natural history museums are repositories of zoological specimens Study skins Bird and mammal specimens are conserved as dry study skins, a form of taxidermy. The skin is removed from the animal's carcass, treated with absorbents, and filled with cotton or polyester batting (In the past plant fibres or sawdust were used). Bird specimens have a long, thin, wooden dowel wrapped in batting at their center. The dowel is often intentionally longer than the bird's body and exits at the animal's vent. This exposed dowel provides a place to handle the bird without distu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
