Rio Grande Silvery Minnow
The Rio Grande silvery minnow or Rio Grande minnow (''Hybognathus amarus'') is a small herbivorous North American fish. It is one of the seven North American members of the genus ''Hybognathus'', in the cyprinid family. The Rio Grande silvery minnow is one of the most endangered fish in North America, according to the U. S. Fish and Wildlife Service (USFWS). They were classified as endangered in the U.S. in 1994, and now are found in less than 5 percent of their natural habitat in the Rio Grande. Historically, the minnow was found from Española, New Mexico, to the Gulf of Mexico in Texas. Now it can only be seen between Cochiti Dam and Elephant Butte Reservoir. Description It is a stout silvery minnow with moderately small eyes and a small mouth. Adults may reach 3.5 inches in total length. Diet and behavior Rio Grande silvery minnows are herbivores whose diet is believed to consist of river plants and benthic macroinvertabrates, though there is little research into their diet d ...

Carl Leavitt Hubbs
Carl Leavitt Hubbs (October 19, 1894 – June 30, 1979) was an American ichthyologist. Biography Youth He was born in Williams, Arizona. He was the son of Charles Leavitt and Elizabeth (née Goss) Hubbs. His father had a wide variety of jobs (farmer, iron mine owner, newspaper owner). The family moved several times before settling in San Diego where he got his first taste of natural history. After his parents divorced in 1907, he lived with his mother, who opened a private school in Redondo Beach, California. His maternal grandmother Jane Goble Goss, one of the first female doctors, showed Hubbs how to harvest shellfish and other sea creatures. One of his teachers, impressed by Hubbs's abilities in science, recommended that he study chemistry at the University of Berkeley. The family moved once more to Los Angeles. In Los Angeles, George Bliss Culver, one of the many volunteers of David Starr Jordan, encouraged Hubbs to abandon his study of birds and instead to study fish, par ...

Hybognathus Regius
The eastern silvery minnow (''Hybognathus regius'') is a freshwater fish. They are characterized by their lack of barbels. In appearance, they are similar to shiners, but the lower jaw is crescent-shaped rather than U-shaped and there is a secondary loop in the gut, which is sometimes visible through the body wall of preserved specimen.

Hybognathus Placitus
The plains minnow (''Hybognathus placitus'') is one of the 324 fish species found in central United States . It is a large minnow that was once a common bait fish. The plains minnow requires shallow, slow-moving streams to complete its life cycle. Pollution, dams, and introduced sport fish have caused populations to decline. It ranges from the Mississippi River in Tennessee west in the Missouri, Arkansas, Red, Brazos, Canadian and Colorado River drainages from Montana and North Dakota south to New Mexico and Texas. It is one of the more common fishes of the western plains. Physical Description The plains minnow is a large minnow in the family Cyprinidae that averages 127 millimeters (5 inches) in total length. Their colors range from brown to olive dorsally, silver laterally, and white ventrally. The plains minnow has between 34 and 42 scales and possesses a stripe along the lateral line.

Hybognathus Nuchalis
The Mississippi silvery minnow (''Hybognathus nuchalis'') is a species of fish in the family Cyprinidae. It is one of the 324 fish species found in Tennessee. Relative to other minnows, the Mississippi Silvery Minnow is a large minnow. These minnows require a body of water with little to no current. The most documentation of these minnows is from the Little and Great Miami river along with the Ohio river and tributes off these rivers. In terms of conservation, the population in Ohio is at an all-time low, but overall there is little conservation concern about this specific minnow. In general there has been little research done on the Mississippi silvery minnow. Distribution The Mississippi silvery minnow is native to North America. North America these fish have been documented to live in low land areas of the Mississippi river basin. This stretches from Minnesota down to Ohio. There is also documentation of these minnows in the Mississippi river all the way to the Gulf of Mexico. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...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.
