Cottus Cyclophthalmus
''Cottus cyclophthalmus'' is a species of freshwater ray-finned fish belonging to the Family (biology), family Cottidae, the typical sculpins. This species is found in northeastern Europe, in the Neman river, Neman River and Venta (river), Venta River drainages in the basin of the Baltic Sea. This species is similar to the European bullhead (''Cottus gobio'') but is distinguished by uts round, protruding and tubular eyes set close to the front of head; papillae in the skin on the top and sides of the head, a scale-less body without any bony prickles and a complete sensory canal on the flanks which has 32–36 pores. It is classified within the subgenus ''Cottus'' and the Specific name (zoology), specific name ''cyclophthalmus'' is a compound of ''cyclos'', meaning "round", and ''ophthalmus'', which mean "eye", an allusion to the round, tubular eyes.

Vytautas Kesminas
Vytautas (c. 135027 October 1430), also known as Vytautas the Great (Lithuanian: ', be, Вітаўт, ''Vitaŭt'', pl, Witold Kiejstutowicz, ''Witold Aleksander'' or ''Witold Wielki'' Ruthenian: ''Vitovt'', Latin: ''Alexander Vitoldus'', Old German: ''Wythaws or Wythawt'') from the late 14th century onwards, was a ruler of the Grand Duchy of Lithuania. He was also the Prince of Grodno (1370–1382), Prince of Lutsk (1387–1389), and the postulated king of the Hussites. In modern Lithuania, Vytautas is revered as a national hero and was an important figure in the national rebirth in the 19th century. ''Vytautas'' is a popular male given name in Lithuania. In commemoration of the 500-year anniversary of his death, Vytautas Magnus University was named after him. Monuments in his honour were built in many towns in the independent Lithuania during the interwar period from 1918 to 1939. It is known that Vytautas himself knew and spoke in the Lithuanian language with Jogaila. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Family (biology)
Family ( la, familia, plural ') 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". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Cottidae
The Cottidae are a family of fish in the superfamily Cottoidea, the sculpins. It is the largest sculpin family, with about 275 species in 70 genera.Kane, E. A. and T. E. Higham. (2012)Life in the flow lane: differences in pectoral fin morphology suggest transitions in station-holding demand across species of marine sculpin.''Zoology'' (Jena) 115(4), 223-32. They are referred to simply as cottids to avoid confusion with sculpins of other families. Cottids are distributed worldwide, especially in boreal and colder temperate climates. The center of diversity is the northern Pacific Ocean. Species occupy many types of aquatic habitats, including marine and fresh waters, and deep and shallow zones. A large number occur in near-shore marine habitat types, such as kelp forests and shallow reefs. They can be found in estuaries and in bodies of fresh water. Most cottids are small fish, under in length. The species ''Scorpaenichthys marmoratus'' can be up to in length.Froese, R. and D ...

Venta (river)
The Venta (Latvian pronunciation , Lithuanian , , , Livonian ''Vǟnta joug'') is a river in north-western Lithuania and western Latvia. Its source is near Kuršėnai in the Lithuanian Šiauliai County. It flows into the Baltic Sea at Ventspils in Latvia. On the territory of Lithuania along the Venta are cities Užventis, Kuršėnai, Venta, Viekšniai and Mažeikiai.

Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The " Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Bullhead
The European bullhead (''Cottus gobio'') is a freshwater fish that is widely distributed in Europe, mainly in rivers. It is a member of the family Cottidae, a type of sculpin. It is also known as the miller's thumb, freshwater sculpin, common bullhead, and cob. The European bullhead is a small demersal fish that lives both in cold, clear, fast-flowing small streams and in middle-sized rivers. It also occurs on gravelly shores of cold lakes. Further, it thrives in diluted brackish water of the Northern Baltic Sea. Description The bullhead has a large broad head and tapering body, large fins and a rounded tail. The eyes are located near the top of the head. To the distinction from the other freshwater sculpin species found in Northern Europe, it can be told from the alpine bullhead ''Cottus poecilopus'' by the fact that the rays of its pelvic fins are of similar lengths while the first and last rays are longer in the alpine bullhead. It can be distinguished from the fourhorn sc ... [...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 ...

Cottus (fish)
''Cottus'' is a genus of the mainly freshwater ray-finned fishes belonging to the family Cottidae, the typical sculpins. They are often referred to as the "freshwater sculpins", as they are the principal genus of sculpins to be found in fresh water. They are native to the Palearctic and Nearctic. They are small fish, mostly less than in length, although a few species can reach twice that size. Taxonomy ''Cottus'' was first proposed as a genus by Carl Linnaeus in the 10th edition of the ''Systema Naturae'' when he described the European bullhead (''Cottus gobio'') and in 1850 this species was designated as the type species of the genus by the French ichthyologist Charles Frédéric Girard. The 5th edition of the ''Fishes of the World'' classifies this genus within the subfamily Cottinae of the family Cottidae. Other authorities have found that the Cottidae, as delimited in the 5th edition of Fishes of the World, is paraphyletic and that the monophyletic grouping is the freshwate ...
