Johann Anton Güldenstädt
Johann Anton Güldenstädt (26 April 1745 in Riga, Latvia – 23 March 1781 in St. Petersburg, Russia) was a Baltic German natural history, naturalist and explorer in Russian service. Güldenstädt lost both his parents early, and from 1763 onwards studied pharmacy, botany and natural history in Berlin. At the age of 22, he obtained his doctorate in medicine at the Viadrina European University, University of Frankfurt in 1767. In the following year, he joined the Russian Academy of Sciences, Russian Imperial Academy of Sciences' expedition sent by Catherine II of Russia to explore the Russian empire's southern frontier. Güldenstädt travelled through Ukraine and the Astrakhan Oblast, Astrakhan region, as well as the northern Caucasus and Georgia (country), Georgia, both of which were almost entirely beyond the borders of the Russian empire. In March 1775 he returned to St Petersburg. The results of the expedition and Güldenstädt's edited expedition journal were published after ...

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 ...

Luciobarbus
''Luciobarbus'' is a genus of ray-finned fishes in the family Cyprinidae. Its members are found in fresh and brackish waters of southern Europe, northern Africa, the wider Near East, the Aral and Caspian Seas, and rivers associated with these. Several species in the genus are threatened. Most species are fairly small to medium-sized cyprinids, but the genus also includes several members that can surpass in length and the largest, the mangar (''L. esocinus'') can reach . Systematics The type species is ''Luciobarbus esocinus'', for which the genus was established by Heckel in 1843. The type species scientific name essentially means "pike-like pike-barbel" (after the northern pike, ''Esox lucius''), though a more aliteral translation would be "pike-like wolf-barbel". Like many other cyprinids, the present genus was long included in ''Barbus''. It appears to be a very close relative of the typical barbels – which include that genus type species, ''Barbus barbus'' –, ...

Central Asia
Central Asia, also known as Middle Asia, is a subregion, region of Asia that stretches from the Caspian Sea in the west to western China and Mongolia in the east, and from Afghanistan and Iran in the south to Russia in the north. It includes the former Soviet Union, Soviet republics of the Soviet Union, republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan, which are colloquially referred to as the "-stans" as the countries all have names ending with the Persian language, Persian suffix "-stan", meaning "land of". The current geographical location of Central Asia was formerly part of the historic region of Turkestan, Turkistan, also known as Turan. In the pre-Islamic and early Islamic eras ( and earlier) Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian languages, Eastern Iranian-speaking Bactrians, Sogdians, Khwarezmian language, Chorasmians and the semi-nomadic Scythians and Dahae. After expansion by Turkic peop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iran
Iran, officially the Islamic Republic of Iran, and also called Persia, is a country located in Western Asia. It is bordered by Iraq and Turkey to the west, by Azerbaijan and Armenia to the northwest, by the Caspian Sea and Turkmenistan to the north, by Afghanistan and Pakistan to the east, and by the Gulf of Oman and the Persian Gulf to the south. It covers an area of , making it the 17th-largest country. Iran has a population of 86 million, making it the 17th-most populous country in the world, and the second-largest in the Middle East. Its largest cities, in descending order, are the capital Tehran, Mashhad, Isfahan, Karaj, Shiraz, and Tabriz. The country is home to one of the world's oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. It was first unified by the Medes, an ancient Iranian people, in the seventh century BC, and reached its territorial height in the sixth century BC, when Cyrus the Great fo ...

Fish Described In 1773
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. Most fis ...
