Meda Fulgida
The spikedace (''Meda fulgida'') is an endangered species of ray-finned fish in the family Cyprinidae. It is found in Arizona and New Mexico in the United States. It lives in fast-moving streams. Description The maximum length of the spikedace rarely exceeds 7.5 cm. It usually has a slender body, with a somewhat compressed front, and is strongly compressed at the caudal peduncle, with a fairly pointed snout and contains a slightly subterminal mouth with large eyes. The dorsal fin origin is behind the pelvic fin origin. The scales are present only as small, deeply embedded plates. The first spinous ray of the dorsal fin is the strongest and most sharp-pointed. The spikedace has seven dorsal fin-rays and typically 9 anal fin-rays. The spikedace skin is olive-gray to light brown above, with a brilliant silver side, often with blue reflections, and with black specks and blotches on the back and upper side. The breeding male has a spectacular, bright, brassy yellow head and fins. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Charles Frédéric Girard
Charles Frédéric Girard (8 March 1822 – 29 January 1895) was a French biologist specializing in ichthyology and herpetology. Born in Mulhouse, France, he studied at the College of Neuchâtel, Switzerland, as a student of Louis Agassiz. In 1847, he accompanied Agassiz as his assistant to Harvard University. Three years later, Spencer Fullerton Baird called him to the Smithsonian Institution to work on its growing collection of North American reptiles, amphibians and fishes. He worked at the museum for the next ten years and published numerous papers, many in collaboration with Baird. In 1854, he was naturalized as a U.S. citizen. Besides his work at the Smithsonian, he managed to earn an M.D. from Georgetown University in Washington, D.C. in 1856. In 1859 he returned to France and was awarded the Cuvier Prize by the Institute of France for his work on the North American reptiles and fishes two years later. When the American Civil War broke out, he joined the Confederate ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

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 ...

Arizona
Arizona ( ; nv, Hoozdo Hahoodzo ; ood, Alĭ ṣonak ) is a state in the Southwestern United States. It is the 6th largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona is part of the Four Corners region with Utah to the north, Colorado to the northeast, and New Mexico to the east; its other neighboring states are Nevada to the northwest, California to the west and the Mexican states of Sonora and Baja California to the south and southwest. Arizona is the 48th state and last of the contiguous states to be admitted to the Union, achieving statehood on February 14, 1912. Historically part of the territory of in New Spain, it became part of independent Mexico in 1821. After being defeated in the Mexican–American War, Mexico ceded much of this territory to the United States in 1848. The southernmost portion of the state was acquired in 1853 through the Gadsden Purchase. Southern Arizona is known for its desert cl ...

Gila River
The Gila River (; O'odham ima Keli Akimel or simply Akimel, Quechan: Haa Siʼil, Maricopa language: Xiil) is a tributary of the Colorado River flowing through New Mexico and Arizona in the United States. The river drains an arid watershed of nearly that lies mainly within the U.S., but also extends into northern Sonora, Mexico. Indigenous peoples have lived along the river for at least 2,000 years, establishing complex agricultural societies before European exploration of the region began in the 16th century. However, European Americans did not permanently settle the Gila River watershed until the mid-19th century. During the 20th century, human development of the Gila River watershed prompted the construction of large diversion and flood control structures on the river and its tributaries, and consequently the Gila now contributes only a small fraction of its historic flow to the Colorado. The historic natural discharge of the river is around , and is now only . These engin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Aravaipa Creek
Aravaipa Creek is a drainage between three mountain ranges in southwest Graham County, Arizona – the Galiuro Mountains, the Santa Teresa Mountains and the Pinaleno Mountains. These mountains are part of the high altitude Madrean Sky Islands located in southern Arizona and New Mexico in the United States, and northern Sonora and Chihuahua states in Mexico. Aravaipa Creek originates on the southeast flank of the Galiuro Mountains at Durkee Canyon and Blue Peak at .Arizona Road and Recreation Atlas, pp. 82–83. It then flows northwest through the narrow, fault-blocked Aravaipa Valley with the Pinaleno Mountains bordering the valley on the east and the Santa Teresa Mountains bordering on the northeast. On the west side of the valley, the creek follows the northeast and north perimeter of the Galiuro Mountains massif flowing northwest, west, and then southwest through and around the range's north end to meet the San Pedro River a few miles south of Dudleyville.

San Pedro River (Arizona)
The San Pedro River is a northward-flowing stream originating about south of the international border south of Sierra Vista, Arizona, in Cananea Municipality, Sonora, Mexico. The river starts at the confluence of other streams (Las Nutrias and El Sauz) just east of Sauceda, Cananea. Within Arizona, the river flows north through Cochise County, Arizona, Cochise County, Pima County, Arizona, Pima County, Graham County, Arizona, Graham County, and Pinal County, Arizona, Pinal County to its confluence with the Gila River, at Winkelman, Arizona. It is the last major, undammed desert river in the Southwestern United States, American Southwest, and it is of major ecological importance as it hosts two-thirds of the avian diversity in the United States, including 100 species of breeding birds and almost 300 species of migrating birds. History The first people to enter the San Pedro Valley were the Clovis people who hunted mammoth here from 10,000 years ago. The San Pedro Valley has the ...

Red Shiner
The red shiner or red-horse minnow (''Cyprinella lutrensis'') is a North American species of freshwater fish in the family Cyprinidae. They are deep-bodied and laterally compressed,Farringer R.T., III, A.A. Echelle, and S.F. Lehtinen. 1979. Reproductive cycle of the red shiner, Notropis lutrensis, in central Texas and south central Oklahoma. ''Transactions of the American Fisheries Society,'' 108, 271-276. and can grow to about three inches in length. For most of the year, both males and females have silver sides and whitish abdomens. Males in breeding coloration, though, have iridescent pink-purple-blue sides and a red crown and fins (except the dorsal fin which remains dark). Red shiners can live up to three years. They are omnivorous; they eat both aquatic and terrestrial invertebrates, as well as algae. Red shiners have also been known to eat the eggs and larvae of native fish found in locations where they have been introduced.Ruppert, J.B., Muth, R.T., Nesler, T.P. (1993). P ...

Leuciscinae
Leuciscinae is a subfamily of the freshwater fish family Cyprinidae, which contains the true minnows. Members of the Old World (OW) clade of minnows within this subfamily are known as European minnows. As the name suggests, most members of the OW clade are found in Eurasia, aside from the golden shiner (''Notemigonus crysoleucas''), which is found in eastern North America. According to ancestral area reconstruction, the subfamily Leuiciscinae is thought to have originated in Europe before becoming widely distributed in parts of Europe, Asia and North America. Evidence for the dispersal of this subfamily can be marked by biogeographical scenarios/observations, geomorphological changes, phylogenetic relationships as well as evidence for vicariance events taking place through time. Through analyses and evidence of divergence time, it was observed that the two monophyletic groups, the phoxinins and the leuciscins, had shared a common ancestor dating to approximately 70.7 million year ...

Freshwater Fish Of The United States
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh wa ...
