Trichromis
The Salvin's cichlid (''Trichromis salvini''), also known as the yellow-belly cichlid or tricolored cichlid, is a species of the family Cichlidae. It is found in rivers of the Atlantic slope of southern Mexico, Belize, and Guatemala. Taxonomy In 2015, McMahan ''et al.'' published a paper placing this species in the genus ''Trichromis''. The relationship of Salvin's cichlid to other Central American cichlid had long been debated. Genetic research by Říčan ''et al.'' revealed that the closest relatives to ''Trichromis'' are the firemouth cichlid and its congeners in the genus ''Thorichthys''. Description The Salvin's cichlid is oblong in shape and has a rather pointed mouth compared to other Central American cichlids. The body is yellow with two lines of black "flowers" along the side and upper half of the back of the fish. These flowers have a blue pearl outline. It has black bars that cross the face, and both sexes have red bellies, which is more pronounced in females, espe ...

Thorichthys
''Thorichthys'' is a genus of cichlid fish that is native to the Atlantic slope of Middle America, ranging from southern Veracruz and the Yucatán Peninsula in Mexico, to Guatemala and Honduras, with introduced populations in a few other countries. They tend to inhabit moderately-flowing to standing water such as rivers, streams, lakes, ditches and lagoons, and they are primarily freshwater fish, although ''T. helleri'' and ''T. meeki'' may occur in slightly brackish habitats. ''Thorichthys'' have somewhat pointy heads and stripes down their body, and mostly feed on invertebrates and detritus. Members of ''Thorichthys'' do not exceed in standard length, and they are popular aquarium fish, especially the well-known firemouth cichlid (''T. meeki''). Genetic evidence shows that ''Thorichthys'' is most closely related to Salvin's cichlid, the only species of the genus ''Trichromis'', which is morphologically and behaviorally rather different. In contrast, ''Thorichthys'' is not p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 ...

Honduras
Honduras, officially the Republic of Honduras, is a country in Central America. The republic of Honduras is bordered to the west by Guatemala, to the southwest by El Salvador, to the southeast by Nicaragua, to the south by the Pacific Ocean at the Gulf of Fonseca, and to the north by the Gulf of Honduras, a large inlet of the Caribbean Sea. Its capital and largest city is Tegucigalpa. Honduras was home to several important Mesoamerican cultures, most notably the Maya, before the Spanish Colonization in the sixteenth century. The Spanish introduced Catholicism and the now predominant Spanish language, along with numerous customs that have blended with the indigenous culture. Honduras became independent in 1821 and has since been a republic, although it has consistently endured much social strife and political instability, and remains one of the poorest countries in the Western Hemisphere. In 1960, the northern part of what was the Mosquito Coast was transferred from Nicara ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Vertebrates Of Belize
Vertebrates () comprise all animal taxa within the subphylum Vertebrata () (chordates with backbones), including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described. Vertebrates comprise such groups as the following: * jawless fish, which include hagfish and lampreys * jawed vertebrates, which include: ** cartilaginous fish (sharks, rays, and ratfish) ** bony vertebrates, which include: *** ray-fins (the majority of living bony fish) *** lobe-fins, which include: **** coelacanths and lungfish **** tetrapods (limbed vertebrates) Extant vertebrates range in size from the frog species ''Paedophryne amauensis'', at as little as , to the blue whale, at up to . Vertebrates make up less than five percent of all described animal species; the rest are invertebrates, which lack vertebral columns. The vertebrates traditionally include the hagfish, which do not ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cichlid Fish Of Central America
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of '' Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquar ...

Taxa Named By Albert Günther
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ...

Fish Described In 1862
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...

Hardy Fish
A hardy fish is any fish which is easy to maintain in a home aquarium due to its ability to adapt to a wide range of water parameters. Such fish are good starter fish and ideal for 'cycling' an aquarium (i.e. reducing ammonia and nitrites to effectively zero.) Examples of hardy freshwater fish include Poecilids such as the guppy, molly, swordtail and platy, most species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ... of betta, zebra danios, and some tetras. Generally, fish are hardy only when they have been tank-bred, since wild-caught fish may take many generations to adapt to life in captivity. Fishkeeping {{Fishkeeping-stub ...

Jaw Protrusion
Most bony fishes have two sets of jaws made mainly of bone. The primary oral jaws open and close the mouth, and a second set of pharyngeal jaws are positioned at the back of the throat. The oral jaws are used to capture and manipulate prey by biting and crushing. The pharyngeal jaws, so-called because they are positioned within the pharynx, are used to further process the food and move it from the mouth to the stomach. Cartilaginous fishes, such as sharks and rays, have one set of oral jaws made mainly of cartilage. They do not have pharyngeal jaws. Generally jaws are articulated and oppose vertically, comprising an upper jaw and a lower jaw and can bear numerous ordered teeth. Cartilaginous fishes grow multiple sets ''(polyphyodont)'' and replace teeth as they wear by moving new teeth laterally from the medial jaw surface in a conveyor-belt fashion. Teeth are replaced multiple times also in most bony fishes, but unlike cartilaginous fishes, the new tooth erupts only after the ...

Piscivore
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 signific ...

South Florida
South Florida is the southernmost region of the U.S. state of Florida. It is one of Florida's three most commonly referred to directional regions; the other two are Central Florida and North Florida. South Florida is the southernmost part of the continental United States and the only region of the continental U.S. that includes some areas with a tropical climate. South Florida is dominated by the Miami metropolitan area and the Everglades, and contains the Florida Keys, three U.S. national parks (namely Biscayne, Dry Tortugas, and Everglades), and multiple cities. While the term most commonly refers to the Keys and Greater Miami, interpretations vary on the inclusion of some other parts of Florida within the South Florida region, most commonly the southern parts of the Tampa Bay area, the inclusion of Southwest Florida and its cities, and the Treasure Coast. Composition As with all vernacular regions, South Florida has no official boundaries or status and is defined different ...
