Chiapaheros
''Chiapaheros grammodes'' is a species of cichlid fish found in the upper part of the Grijalva River basin in southern Mexico and far western Guatemala. Adults generally inhabit areas with moderate to strong current, but they can also be found in backwaters and juveniles generally occur in calm waters. This species is the only known member of its genus, but historically it has been placed in several other genera. It reaches up to about in standard length. ''C. grammodes'' is relatively aggressive and quite predatory, tending towards piscivory. Both natural and aquarium hybrids have occurred between this species and ''Vieja ''Vieja'' is a genus of cichlid fish from Central America and Mexico.

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 "f ...

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 demons ...

Monotypic Ray-finned Fish Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Vieja
''Vieja'' is a genus of cichlid fish from Central America and Mexico. The majority of the species are freshwater fish found in stagnant or slow-moving waters of southern Mexico to El Salvador, but ''V. maculicauda'', which also occurs in brackish waters, ranges south to Panama. They are high-bodied cichlids that reach lengths of up to depending on the exact species. ''Vieja'' feed mostly on vegetable matter, but may also take small invertebrates. Taxonomy and species Historically, ''Vieja'' was included in ''Cichlasoma''. Once recognized as its own genus, it sometimes included most of the superficially similar, relatively large and high-bodied cichlids of Central America and southern Mexico, but several of these are now considered to belong to separate genera: '' Chuco'', ''Cincelichthys'', '' Isthmoheros'', '' Kihnichthys'', ''Maskaheros'' and '' Oscura'' (''Oscuro'' might still be better merged with ''Vieja'', but this remains unconfirmed). Conversely, ''Vieja'' has sometime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piscivory
A piscivore () is a carnivorous animal that eats primarily fish. The name ''piscivore'' is derived . Piscivore is equivalent to the Greek-derived word ichthyophage, both of which mean "fish eater". Fish were the diet of early tetrapod evolution (via water-bound amphibians during the Devonian period); insectivory came next; then in time, the more terrestrially adapted reptiles and synapsids evolved herbivory. Almost all predatory fishes (most sharks, tuna, billfishes, pikes etc.) are obligated piscivores. Some non-piscine aquatic animals, such as whales, sea lion and crocodilians, are not completely piscivorous, often also preying on invertebrates, marine mammals, waterbirds and even wading land animals in addition to fish; while others, such as the bulldog bat and gharial, are strictly dependent on fish for food. Some creatures, including cnidarians, octopuses, squid, spiders, cetaceans, grizzly bears, jaguars, wolves, snakes, turtles and sea gulls, may have fish as significa ...

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

Grijalva River
Grijalva River, formerly known as ''Tabasco River'', ( es, Río Grijalva, known locally also as Río Grande de Chiapas, Río Grande and Mezcalapa River) is a long river in southeastern Mexico."Grijalva." ''Merriam-Webster's Geographical Dictionary'', 3rd ed. 2001. () Springfield, MA: Merriam-Webster Inc., p. 450. It is named after Juan de Grijalva who visited the area in 1518. The river rises from Río Grande de Chiapas in southeastern Chiapas and flows from Chiapas to the state of Tabasco through the Sumidero Canyon into the Bay of Campeche. Begins as "Río Grande de Chiapas" or "Río Mezcalapa", later, Río Grande is stopped at the Angostura Dam (Mexico), one of the largest reservoirs in Mexico, and then its course is now named "Grijalva River". The river's drainage basin is in size. Because of the close connection to the Usumacinta River (the two combine, flowing into the Gulf of Mexico in a single delta), they are often regarded as a single river basin, the Grijalva-Us ...
