Farsi Toothcarp
The Farsi toothcarp (''Esmaeilius persicus'') is a species of pupfish belonging to the family Aphaniidae. It is endemic to the Maharloo Lake Basin in Iran, residing in springs, lagoons, and marshes containing fresh to brackish water. Taxonomy The species name, ''persicus'', refers to Persia, the ancient name of Iran, where the fish is found. It was originally described as ''Cyprinodon persicus'', later ''Aphanius''. Then, in late 2011, a Late Miocene fossil genus ''Brachylebias'' was synonymised with ''Aphanius'', which suggested a change to the extant species as there was a ''B. persicus'' which preoccupied the name. The replacement name proposed was ''farsicus'', referring to the Fars province, but this was not universally accepted. Finally, in 2020 it was added to a new genus ''Esmaeilius'' as ''Esmaeilius persicus''. Description Farsi toothcarp reach approximately in length. Like all members of its genus, the fish show sexual dimorphism. Females have numerous alternati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Late Miocene
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene Epoch made up of two stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma (million years ago) to 5.333 Ma. The evolution of life The gibbons (family Hylobatidae) and orangutans (genus ''Pongo'') are the first groups to split from the line leading to the hominins, including humans, then gorillas (genus ''Gorilla''), and finally, chimpanzees and bonobo The bonobo (; ''Pan paniscus''), also historically called the pygmy chimpanzee and less often the dwarf chimpanzee or gracile chimpanzee, is an endangered great ape and one of the two species making up the genus '' Pan,'' the other being the co ...s (genus '' Pan''). The splitting date between hominin and chimpanzee lineages is placed by some between 4 to 8 million years ago, that is, during the Late Miocene.

Fauna Of Iran
The wildlife of Iran include the fauna and flora of Iran. One of the most famous wildlife of Iran is the critically endangered Asiatic cheetah (''Acinonyx jubatus venaticus''), which today survives only in Iran. History The wildlife of Iran first been partly described by Hamdallah Mustawfi in the 14th century who only referred to animals. In the 18th and 19th centuries, Samuel Gottlieb Gmelin and Édouard Ménétries explored the Caspian Sea area and the Talysh Mountains to document Caspian fauna. Several naturalists followed in the 19th century, including Filippo de Filippi, William Thomas Blanford, and Nikolai Zarudny who documented mammal, bird, reptile, amphibian and fish species. Flora More than one-tenth of the country is forested. The most extensive growths are found on the mountain slopes rising from the Caspian Sea, with stands of oak, ash, elm, cypress, and other valuable trees. On the plateau proper, areas of scrub oak appear on the best-watered mountain slopes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Esmaeilius
''Esmaeilius'' is a genus of toothcarps in the family Aphaniidae. They are native to Iran and one species extending to Iraq. Most species in the genus have very small distributions and all are seriously threatened. Etymology The generic name pertains to Hamid Reza Esmaeili, for his contribution to the understanding of diversity within the family Aphaniidae Aphaniidae, the Oriental killifishes, are a family of the order Cyprinodontiformes. The 42 extant species of the family inhabit inland waters, rivers and lagoons. The distribution of these species extends from the entire Mediterranean region t ....

Esmaeilius Sophiae
''Esmaeilius sophiae'', the Soffia toothcarp, is a species of killifish belonging to the family Aphaniidae. It is native to Iran and Iraq which includes the Kor River basin of the Fars Province in Iran, Namak lake and Tigris River basin. They are one of the subclades of the Inland and Inland-related ''Aphanius'' Species (IIRAS) and they are part of the richest of the 3 subclades. They can be found in freshwater but also occur in saline water. Distribution and habitat The Soffia killifish is mainly herbivorous, nonmigratory, and lives near the bottom of mostly fresh bodies of water, such as rivers and springs. Baensch, H.A. and R.

Caudal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerat ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pupfish
Pupfish are a group of small killifish belonging to ten genera of the family Cyprinodontidae of ray-finned fish. Pupfish are especially noted for being found in extreme and isolated situations. They are primarily found in North America, South America, and the Caribbean region, but '' Aphanius'' species are from southwestern Asia, northern Africa, and southern Europe. As of August 2006, 120 nominal species and 9 subspecies were known. Several pupfish species are extinct and most extant species are listed. In the U.S., the most well-known pupfish species may be the Devil's Hole Desert Pupfish, native to Devil's Hole on the Nevada side of Death Valley National Park. Since 1995 the Devil's Hole Pupfish has been in a nearly steady decline, where it was close to extinction at 35–68 fish in 2013. The common name is said to derive from the mating habits of the males, whose activities vaguely resemble puppies at play. Carl L. Hubbs Carl Leavitt Hubbs (October 19, 1894 – June 30, ...

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 ...

Fresh Water
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to surv ...
