Romanogobio Antipai
The Danube delta gudgeon (''Romanogobio antipai'') is a species of freshwater ray-finned fish belonging to the family Gobionidae, the gudgeons. This fish is endemic to the lower Danube in Bulgaria, Romania and Ukraine. It was last recorded in the 1960s, with many studies conducted in its home range, all failing to find the species, until in 2016 a specimen was collected from the Bulgarian sector of the Danube. Named in memory of Romanian zoologist Grigore Antipa Grigore Antipa (; 27 November 1867 in Botoșani – 9 March 1944 in Bucharest) was a Romanian naturalist, Zoology, zoologist, Ichthyology, ichthyologist, Ecology, ecologist, Oceanography, oceanologist, Darwinism, Darwinist biologist who studie ...

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class (biology), class of Osteichthyes, bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fish fin, fins made of webbings of skin supported by radially extended thin bony spine (zoology), spines called ''lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister taxon, sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation (anatomy), articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they domi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Gobionidae
Gobioninae is a monophyletic family of Eurasian cyprinoid fishes. This is a species rich clade which, as a subfamily of the Cyprinidae was divided into five tribes: Gobionini, Pseudogobionini, Hemibarbini, Coreiini, and Sarcocheilichthyini. These subdivisions are not recognised by '' Eschmeyer's Catalog of Fishes''. To adapt to different masticatory operations, members of the Gobioninae developed various types of pharyngeal bones and teeth; some have intermediate pharyngeal bones with rows of diverse teeth (conical, compressed, and coarsely compressed), others have broad pharyngeal bones with a single row of molar teeth. Some Gobioninae have narrow pharyngeal bones with a row of extremely compressed teeth. Genera These genera are included in the subfamily Gobioninae according to ''Eschmeyer's Catalog of Fishes'': * '' Abbottina'' D. S. Jordan & Fowler, 1903 * '' Acanthogobio'' Herzenstein, 1892 * '' Belligobio'' D. S. Jordan & Hubbs, 1925 * '' Biwia'' D. S. Jordan & ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Danube
The Danube ( ; see also #Names and etymology, other names) is the List of rivers of Europe#Longest rivers, second-longest river in Europe, after the Volga in Russia. It flows through Central and Southeastern Europe, from the Black Forest south into the Black Sea. A large and historically important river, it was once a frontier of the Roman Empire. In the 21st century, it connects ten European countries, running through their territories or marking a border. Originating in Germany, the Danube flows southeast for , passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine. Among the many List of cities and towns on the river Danube, cities on the river are four national capitals: Vienna, Bratislava, Budapest, and Belgrade. Its drainage basin amounts to and extends into nine more countries. The Danube's longest headstream, the Breg (river), Breg, rises in Furtwangen im Schwarzwald, while the river carries its name from its ...

Grigore Antipa
Grigore Antipa (; 27 November 1867 in Botoșani – 9 March 1944 in Bucharest) was a Romanian naturalist, Zoology, zoologist, Ichthyology, ichthyologist, Ecology, ecologist, Oceanography, oceanologist, Darwinism, Darwinist biologist who studied the fauna of the Danube Delta and the Black Sea. Between 1892 and 1944 he was the director of the Grigore Antipa National Museum of Natural History, 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 sch ...

Fish Described In 1953
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...
