Somali Blind Barb
The Somalian blind barb (''Barbopsis devecchii'') is a ray-finned fish species in the family (biology), family Cyprinidae. It is the only member of the genus ''Barbopsis''. This Cavefish, troglobitic fish is found only in Somalia. There are two other cavefish species in Somalia: the cyprinid ''Phreatichthys andruzzii'' and the catfish ''Uegitglanis zammaranoi''.Romero, A., editor (2001). ''The Biology of Hypogean Fishes.''

Lodovico Di Caporiacco
Ludovico di Caporiacco (22 January 1900, in Udine – 18 July 1951, in Parma) was an Italian arachnologist. Caporiacco took part in an expedition to the Jebel Uweinat, a mountain massif in the boundary region of Sudan, Libya, and Egypt. On the mission, he, together with Hungarian explorer László Almásy, discovered the prehistoric rock paintings of Ain Doua in 1933. In 1943 he was appointed professor of zoology to the faculty of sciences at the University of Parma. He was the author of numerous scientific papers on arachnids native to Italy and other Mediterranean regions. He also published articles on species indigenous to East Africa, Central Asia (Himalayas and the Karakoram The Karakoram () is a mountain range in the Kashmir region spanning the border of Pakistan, China, and India, with the northwestern extremity of the range extending to Afghanistan and Tajikistan. Most of the Karakoram mountain range is withi ...) as well as Central and South America. He was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 1,780 species divided into 166 valid genera. Cyprinids range from about in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless, or ''agastric'', fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used to identify spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Cavefish
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, Troglomorphism, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish, and hypogean fish.Romero, Aldemaro, editor (2001). ''The Biology of Hypogean Fishes.'' Developments in Environmental Biology of Fishes. Helfman, G.S. (2007). ''Fish Conservation: A Guide to Understanding and Restoring Global Aquatic Biodiversity and Fishery Resources'', pp. 41–42. Island Press. There are more than 200 Species description, scientifically described species of obligate cavefish found on all continents, except Antarctica. Although widespread as a group, many species have very small ranges and are Threatened species, threatened.Fenolio, D.B.; Zhao, Y.; Niemiller, M.L.; and Stout, J. (2013).

Somalia
Somalia, officially the Federal Republic of Somalia, is the easternmost country in continental Africa. The country is located in the Horn of Africa and is bordered by Ethiopia to the west, Djibouti to the northwest, Kenya to the southwest, the Gulf of Aden to the north, and the Indian Ocean to the east. Somalia has the longest coastline on Africa's mainland. Somalia has an estimated population of 18.1 million, of which 2.7 million live in the capital and largest city, Mogadishu. Around 85% of Somalia's residents are ethnic Somali people, Somalis. The official languages of the country are Somali language, Somali and Arabic, though Somali is the Languages of Somalia, primary language. Somalia has historic and religious ties to the Arab world. The people in Somalia are mainly Muslims, following the Sunni Islam, Sunni branch.. In antiquity, Somalia was an important commercial center.

Phreatichthys Andruzzii
''Garra andruzzii'', a species of cyprinid fish, formerly the only species of the genus ''Phreatichthys'', and is endemic to Somalia Somalia, officially the Federal Republic of Somalia, is the easternmost country in continental Africa. The country is located in the Horn of Africa and is bordered by Ethiopia to the west, Djibouti to the northwest, Kenya to the southwest, th .... This cave-adapted fish is whitish (not pigmented) and blind. It has no scales. It is considered to have evolved in the cave environment for some two million years. Its former generic name derives from the Greek words ''phreasatos'' for spring, and ''ichthys'' for fish. It grows to a maximum length of . This fish is the first animal discovered that does not adjust its biological clock with the light of the sun. It has an unusual internal clock, which measures the passage of time with an extremely long period (up to 47 hours). It is also completely blind to all light stimuli. Two other cavefish sp ...

Uegitglanis Zammaranoi
''Uegitglanis zammaranoi'' is the only species of catfish (order Siluriformes) in the genus ''Uegitglanis'' of the family Clariidae. It is endemic to Somalia, where it only occurs in caves near the Jubba and the Shebelle Rivers. This species grows to about 10.1 cm (4.0 in) in total length. ''U. zammaranoi'' is hypothesized to be the sister group to '' Heteropneustes'' and the remaining clariids. The problematic relationship of this species to the rest of the family is due to the lack of a labyrinth organ that characterizes the family. Two other cavefish species are in Somalia: the cyprinids '' Barbopsis devecchi'' and ''Phreatichthys andruzzii ''Garra andruzzii'', a species of cyprinid fish, formerly the only species of the genus ''Phreatichthys'', and is endemic to Somalia Somalia, officially the Federal Republic of Somalia, is the easternmost country in continental Africa.
