Kihnichthys
''Kihnichthys ufermanni'', the Usumacinta cichlid, is a species of cichlid found in a few rivers in the Usumacinta River basin in Guatemala and southern Mexico. It typically occurs in rivers that are about wide, fairly deep, have few or no aquaritc plants, and a variable water current. This species is the only known member of its genus, but several of its features, including the chisel-like teeth, are shared with ''Cincelichthys'' and whether they should be merged into a single genus is not yet fully resolved; a review in 2020 recommended that the Usumacinta cichlid should be moved into ''Cincelichthys''. The Usumacinta cichlid reaches a standard length of . The generic name honours the Guatemalan ichthyologist Herman A. Kihn while the specific name honours the German aquarist An aquarist is a person who manages aquariums, either professionally or as a hobby. They typically care for aquatic animals, including fish and marine invertebrates. Some may care for aquatic mammal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cincelichthys
''Cincelichthys'' is a genus of high-bodied cichlids found in southern Mexico to Guatemala Guatemala ( ; ), officially the Republic of Guatemala ( es, República de Guatemala, links=no), is a country in Central America.

Heroini
Heroini is a fish tribe from the Cichlasomatinae subfamily in the cichlid family. All cichlids native to the Greater Antilles, United States (southern Texas), Mexico and northern Central America are members of this tribe. It also includes most cichlid species in southern Central America (where only non-Heroini cichlids are ''Andinoacara'' and ''Geophagus'') and several species from South America (where several other tribes exist). A large percentage of its species were formerly placed in the genus ''Cichlasoma'' (itself now placed in the tribe Cichlasomatini), but have since been moved to other genera. In other classifications the tribe Heroini is placed in the subfamily Cichlinae. Abstract Genera This tribe include about 35 genus and 160 species: * '' Amatitlania'' Schmitter-Soto, 2007 * ''Amphilophus'' Agassiz, 1859 * '' Archocentrus'' Gill, 1877 * ''Astatheros'' Pellegrin, 1904 * ''Australoheros'' Říčan & Kullander, 2006 * ''Caquetaia'' Fowler, 1945 * ''Chiapaheros'' M ...

Caleb D
Caleb (), sometimes transliterated as Kaleb ( he, כָּלֵב, ''Kalev'', ; Tiberian vocalization: Kālēḇ; Hebrew Academy: Kalev), is a figure who appears in the Hebrew Bible as a representative of the Tribe of Judah during the Israelites' journey to the Promised Land. A reference to him is also found in the Quran, although his name is not mentioned (Al-Ma'idah: 20-26). Name According to ''The Jewish Encyclopedia'', "since 'Caleb' signifies dog, it has been thought that the dog was the totem of a clan". The New American Standard Exhaustive Concordance states that the name ''Kaleb'' (Caleb) is related to the word for "dog" (). The Bible was written down centuries before Hebrew diacritics were introduced, and there is no certain knowledge of how the name was pronounced when the biblical text was written. In Modern Hebrew, the name is pronounced ; the modern English pronunciation is a result of the Great Vowel Shift. An alternate Hebrew meaning offered for ''Caleb'' is " ...

Fishkeeping
Fishkeeping is a popular hobby, practiced by aquarists, concerned with keeping fish in a home aquarium or garden pond. There is also a piscicultural fishkeeping industry, serving as a branch of agriculture. Origins of fishkeeping Fish have been raised as food in pools and ponds for thousands of years. Brightly colored or tame specimens of fish in these pools have sometimes been valued as pets rather than food. Many cultures, ancient and modern, have kept fish for both functional and decorative purposes. Ancient Sumerians kept wild-caught fish in ponds, before preparing them for meals. Depictions of the sacred fish of Oxyrhynchus kept in captivity in rectangular temple pools have been found in ancient Egyptian art. Similarly, Asia has experienced a long history of stocking rice paddies with freshwater fish suitable for eating, including various types of catfish and cyprinid.

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term fo ...

Ichthyology
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish ( Chondrichthyes), and jawless fish ( Agnatha). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. Etymology The word is derived from the Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λογία, ''logia'', meaning "to study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were ''hunters and gatherers'' who had learned how to obtain the most ...

Standard Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus (biology)
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. 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 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. phylogenetic analysis should clearly demon ...
