Neogobius Caspius
The Caspian goby (''Neogobius caspius'') is a species of fish endemic to the Caspian Sea where it is only found in brackish waters. It is the largest of the Caspian gobies Gobiidae or gobies is a family of bony fish in the order Gobiiformes, one of the largest fish families comprising more than 2,000 species in more than 200 genera.

Bandar-e Anzali
Bandar-e Anzali ( fa, بندرانزلی, also Romanized as Bandar-e Anzalī; renamed as Bandar-e Pahlavi during the Pahlavi dynasty) is a city of Gilan Province, Iran. At the 2011 census, its population was 144,664. Anzali is one of the most important cities in Iran in terms of tourism, economics, and athletics.

Caspian Sea
The Caspian Sea is the world's largest inland body of water, often described as the world's largest lake or a full-fledged sea. An endorheic basin, it lies between Europe and Asia; east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau of Western Asia. It covers a surface area of (excluding the highly saline lagoon of Garabogazköl to its east) and a volume of . It has a salinity of approximately 1.2% (12 g/L), about a third of the salinity of average seawater. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast. The sea stretches nearly from north to south, with an average width of . Its gross coverage is and the surface is about below sea level. Its main freshwater inflow, Europe's longest river, the Volga, enters at the shallow north end. Two deep ... [...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 ...

Karl Eichwald
Karl Eduard von Eichwald (russian: Эдуард Иванович Эйхвальд, ''Eduard Ivanovich Eykhvald''; 4 July 1795, in Mitau, Courland Governorate – 10 November 1876, in Saint Petersburg) was a Baltic German geologist, physician, and Natural history, naturalist, who worked in Russian Empire, Russia. Career Eichwald was a Baltic German born at Mitau in Courland Governorate. He became a doctor of medicine and professor of zoology in Kazan in 1823; four years later professor of zoology and comparative anatomy at Vilnius; in 1838 professor of zoology, mineralogy and medicine at St. Petersburg; and finally, professor of palaeontology in the institute of mining, mines in that city. He travelled much in the Russian Empire, and was a keen observer of its natural history and geology. He died at St. Petersburg. Eichwald was a supporter of Darwinism. Works His published works include ''Reise auf dem Caspischen Meere und in den Caucasus'', 2 vols. (Stuttgart and Tübingen, 1834 ...

Endemism
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brackish Water
Brackish water, sometimes termed brack water, is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. The word comes from the Middle Dutch root '' brak''. Certain human activities can produce brackish water, in particular civil engineering projects such as dikes and the flooding of coastal marshland to produce brackish water pools for freshwater prawn farming. Brackish water is also the primary waste product of the salinity gradient power process. Because brackish water is hostile to the growth of most terrestrial plant species, without appropriate management it is damaging to the environment (see article on shrimp farms). Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific gr ...

Goby
Goby is a common name for many species of small to medium sized ray-finned fish, normally with large heads and tapered bodies, which are found in marine, brackish and freshwater environments. Traditionally most of the species called gobies have been classified in the order Perciformes as the suborder Gobioidei but in the 5th Edition of ''Fishes of the World'' this suborder is elevated to an order Gobiiformes within the clade Percomorpha. Not all the species in the Gobiiformes are referred to as gobies and the "true gobies" are placed in the family Gobiidae, while other species referred to as gobies have been placed in the Oxudercidae. Goby is also used to describe some species which are not classified within the order Gobiiformes, such as the engineer goby or convict blenny ''Pholidichthys leucotaenia''. The word goby derives from the Latin ''gobius'' meaning "gudgeon", and some species of goby, especially the sleeper gobies in the family Eleotridae and some of the dartfishes are ...

Fish Described In 1831
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 ...

Neogobius
''Neogobius'' is a genus of goby native to Black Sea and the Caspian Sea basins. It is part of the broader Benthophilinae subfamily which is also endemic to the same region. Nevertheless, two ''Neogobius'' species have recently turned out to be highly invasive and spread across Europe and even to the Great Lakes of North America. Species There are currently four recognized species in this genus: * '' Neogobius caspius'' ( Eichwald, 1831) (Caspian goby) * ''Neogobius fluviatilis'' (Pallas, 1814) (Monkey goby) * ''Neogobius melanostomus'' (Pallas, 1814) (Round goby) * '' Neogobius pallasi'' (Berg Berg may refer to: People *Berg (surname), a surname (including a list of people with the name) *Berg Ng (born 1960), Hong Kong actor * Berg (footballer) (born 1989), Brazilian footballer Former states *Berg (state), county and duchy of the Holy ..., 1916) (Caspian sand goby) Of these, ''N. bathybius'', ''N. caspius'' and ''N. pallasi'' are endemic to the Caspian basin.
