Alburnus Danubicus
''Alburnus danubicus'' is a species of ray-finned fish in the genus ''Alburnus''. It was known from coastal lakes in Romania and River Danube in Romania and Bulgaria. It is extinct and has not been recorded since 1943. In 2019, a somewhat mysterious specimen was caught from River Danube, at Petrovaradin, Serbia. It might have been ''Alburnus danubicus'', falsifying its status as an extinct species. Alternatively, it might have been an individual of ''Alburnus mento'' that moved down on the river very far from its native area in Upper Austria Upper Austria (german: Oberösterreich ; bar, Obaöstareich) is one of the nine states or of Austria. Its capital is Linz. Upper Austria borders Germany and the Czech Republic, as well as the other Austrian states of Lower Austria, Styria, a .... The specimen was released alive after photography. This species is found in temperate, benthopelagic, freshwater. Distinguishable by its branched anal-fin rays and lateral line scales. Refe ...

Grigore Antipa
Grigore Antipa (; 27 November 1867 in Botoșani – 9 March 1944 in Bucharest) was a Romanian naturalist, zoologist, ichthyologist, ecologist, oceanologist, Darwinist biologist who studied the fauna of the Danube Delta and the Black Sea. Between 1892 and 1944 he was the director of the Bucharest Natural History Museum, which now bears his name. He is also considered to be the first person to modernize the diorama by emphasizing the three-dimensional aspect and first to use dioramas in a museum setting. He is the scientist who reorganized the Grigore Antipa National Museum of Natural History in the new building that today bears his name, designed by the architect Grigore Cerchez, built in 1906 and inaugurated by Carol I of Romania in 1908. He was elected as member of the Romanian Academy in 1910 and was also a member of several foreign academies. Grigore Antipa founded a school of hydrobiology and ichthyology in Romania.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

River Danube
The Danube ( ; ) is a river that was once a long-standing frontier of the Roman Empire and today connects 10 European countries, running through their territories or being a border. Originating in Germany, the Danube flows southeast for , passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine before draining into the Black Sea. Its drainage basin extends into nine more countries. The largest cities on the river are Vienna, Budapest, Belgrade and Bratislava, all of which are the capitals of their respective countries; the Danube passes through four capital cities, more than any other river in the world. Five more capital cities lie in the Danube's basin: Bucharest, Sofia, Zagreb, Ljubljana and Sarajevo. The fourth-largest city in its basin is Munich, the capital of Bavaria, standing on the Isar River. The Danube is the second-longest river in Europe, after the Volga in Russia. It flows through much of Central and Sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrovaradin
Petrovaradin ( sr-cyr, Петроварадин, ) is a historic town in the Serbian province of Vojvodina, now a part of the city of Novi Sad. As of 2011, the urban area has 14,810 inhabitants. Lying on the right bank of the Danube, across from the main part of Novi Sad, it is built around the Petrovaradin Fortress, historical anchor of the modern city. Name Petrovaradin was founded by the Celts, but its original name is unknown. During Roman administration it was known as ''Cusum''. After the Romans conquered the region from the Celtic tribe of Scordisci, they built the Cusum fortress where present Petrovaradin Fortress now stands. In addition, the town received its name from the Byzantines, who called it ''Petrikon or Petrikov (Πετρικον)'' and who presumably named it after Saint Peter. In documents from 1237, the town was first mentioned under the name ''Peturwarod'' (''Pétervárad''), which was named after Hungarian lord Peter, son of Töre. Petrovaradin was known un ...

Upper Austria
Upper Austria (german: Oberösterreich ; bar, Obaöstareich) is one of the nine states or of Austria. Its capital is Linz. Upper Austria borders Germany and the Czech Republic, as well as the other Austrian states of Lower Austria, Styria, and Salzburg. With an area of and 1.49 million inhabitants, Upper Austria is the fourth-largest Austrian state by land area and the third-largest by population. History Origins For a long period of the Middle Ages, much of what would become Upper Austria constituted Traungau, a region of the Duchy of Bavaria. In the mid-13th century, it became known as the Principality above the Enns River ('), this name being first recorded in 1264. (At the time, the term "Upper Austria" also included Tyrol and various scattered Habsburg possessions in South Germany.) Early modern era In 1490, the area was given a measure of independence within the Holy Roman Empire, with the status of a principality. By 1550, there was a Protestant majority. In 1564, ...

Taxa Named By Grigore Antipa
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1909
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Extinct Animals Of Europe
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
