Kosswigichthys
The scaleless killifish or Hazar toothcarp (''Kosswigichthys asquamatus'') is a species of freshwater fish in the family Aphaniidae. It is the only species in its genus, and is endemic to Lake Hazar Lake Hazar (; ; ) is a rift lake in the Taurus Mountains, 22 km southeast of Elazığ, notable as the source of the Tigris. Formerly known as Lake Geoljuk, the lake was used as an execution site during the Armenian genocide. Sunken city ... in Turkey. It is a pelagic species that comes to shore in spring–early summer to spawn. It is threatened by the falling water levels of Lake Hazar due to water abstraction and reduced rainfall due to climate change.

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 throughout the neighboring states of the Red Sea and Persian Gulf to southwest India. Several species in this family have very small distributions and are seriously threatened. Characteristics Aphaniidae are small fishes that usually grow to a length of . Their bodies are moderately elongated and only slightly flattened at the sides. The mouth is short and their teeth are tricuspid. Scales are complete, but can also be reduced or completely absent. All fins are rounded, dorsal and anal fins similar and are almost symmetrical, the pelvic fins can also be very small. There is usually sexual dimorphism and females are usually larger and have dots or spots on a solid colored background. The males often have horizontal stripes. There can also b ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ...

Fish
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 ...

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 ...

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 ...

Lake Hazar
Lake Hazar (; ; ) is a rift lake in the Taurus Mountains, 22 km southeast of Elazığ, notable as the source of the Tigris. Formerly known as Lake Geoljuk, the lake was used as an execution site during the Armenian genocide. Sunken city Scientists found 4,000-year-old archaeological traces of a city, estimated to have been submerged since 1830, below the lake. Turkey wanted to register this historic 'Sunken City' in Eastern Anatolia Region, eastern Anatolia as a World Heritage Site, UNESCO World Heritage Site. Ebubakar Irmak, mayor of Sivrice, Elazığ, Sivrice, dove into the lake in 2017 and found the remains of churches, walls of a castle, pots, pottery and glazed plates of the citadel with traces of the Seljuk Empire, Seljuk, Byzantine Empire, Byzantine and Ottoman Empire, Ottoman eras. In 2019, amphora tombs were found in the sunken city. References

Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...
