Robert Rush Miller
Robert Rush Miller (April 23, 1916 – February 10, 2003) "was an important figure in American ichthyology and conservation from 1940 to the 1990s." He was born in Colorado Springs, earned his bachelor's degree at University of California, Berkeley in 1938, a master's degree at the University of Michigan in 1943, and a Ph.D. at the University of Michigan in 1944. He received tenure at the University of Michigan in 1954. Together with W. L. Minckley, he discovered a new species of platyfish, '' Xiphophorus gordoni'', that they named in honor of Dr Myron Gordon. He served as the ichthyological editor of ''Copeia'' from 1950 to 1955.

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm 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 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 by scient ...

Endemic
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jalisco
Jalisco (, , ; Nahuatl: Xalixco), officially the Free and Sovereign State of Jalisco ( es, Estado Libre y Soberano de Jalisco ; Nahuatl: Tlahtohcayotl Xalixco), is one of the 31 states which, along with Mexico City, comprise the 32 Federal Entities of Mexico. It is located in Western Mexico and is bordered by six states, which are Nayarit, Zacatecas, Aguascalientes, Guanajuato, Michoacán, and Colima. Jalisco is divided into 125 municipalities, and its capital and largest city is Guadalajara. Jalisco is one of the most economically and culturally important states in Mexico, owing to its natural resources as well as its long history and culture. Many of the characteristic traits of Mexican culture, particularly outside Mexico City, are originally from Jalisco, such as mariachi, ranchera music, birria, tequila, jaripeo, etc., hence the state's motto: "Jalisco es México." Economically, it is ranked third in the country, with industries centered in the Guadalajara metropolit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colima
Colima (), officially the Free and Sovereign State of Colima ( es, Estado Libre y Soberano de Colima), is one of the 31 states that make up the Political divisions of Mexico, 32 Federal Entities of Mexico. It shares its name with its capital and main city, Colima City, Colima. Colima is a small state located in Western Mexico on the central Pacific coast, and includes the four oceanic Revillagigedo Islands. Mainland Colima shares borders with the states of Jalisco and Michoacán. In addition to the capital city of Colima, the main cities are Manzanillo, Colima, Manzanillo and Tecomán. Colima is the fourth smallest state in Mexico and has the second smallest population, but has one of Mexico's highest standards of living and the lowest unemployment. However, Colima is also the state with the highest murder rate per capita and one of the highest crime rates, due to its ports being a contested area for cartels.

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algansea
''Algansea'' is a genus of ray-finned fish in the family Leuciscidae, distributed in the Lerma– Chapala– Grande de Santiago, Pátzcuaro, Armería, Ameca, Ayutla and Tuxpan basins in west-central Mexico (mostly Jalisco, but also surrounding states and the State of Mexico). The genus includes both species that are locally numerous, and species that are highly threatened. Their closest relative is the longfin dace (''Agosia chrysogaster''). ''Algansea'' are fairly small fish that typically are between in standard length, although ''A. lacustris'' and ''A. popoche'' can reach up to . The different species are generally quite similar in their appearance, being yellowish- or olive-brown overall; darker on the upperparts and paler, more silvery on the underparts. They have a long blackish line along the side of the body from the gill covers to the tail base, or a blackish spot at the base of the tail. Species There are currently eight recognized species in this genus: * ''Alga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1978
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. Mos ...
