Gilt Darter
The gilt darter (''Percina evides'') is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It can be found in a number of states in the Mississippi River drainage of the United States although it has been extirpated from some river systems in which it was at one time present, mostly due to siltation and pollution problems. Males are more colorful than females and can grow to a length of about . It is a benthic fish that feeds primarily on small aquatic insect larvae. Males form territories during the breeding season in late spring and early summer. Spawning typically takes place at the upper ends of riffles with sandy and gravelly bottoms interspersed with larger cobbles. Some organisations are endeavouring to conserve populations of the gilt darter and re-introduce it to states where the fish has been extirpated but suitable habitat still exists. Description ...

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] |
Central Stoneroller
The central stoneroller (''Campostoma anomalum'') is a fish in the family Cyprinidae endemic to North America. Biology Stonerollers have a rounded snout overhanging a crescent-shaped mouth, a hard ridge of cartilage on the lower lip, and irregular patches of dark colored scales on the sides of the body. Breeding males have orange colored fins with a black band on the dorsal fin and often on the anal fin; breeding tubercles (keratinized growths) also cover the head, back, and sides of the body. Distribution The central stoneroller is widespread in freshwater streams throughout a large portion of the eastern, central, and midwestern United States. It is present in the Atlantic Ocean, Great Lakes, Mississippi River, and Hudson Bay basins in the US, from New York west to North Dakota and Wyoming and south to South Carolina and Texas.

Silverjaw Minnow
Silverjaw minnows (''Ericymba buccata'') are part of the family Cyprinidae, which includes carps and minnows. With over 300 known species, there are more species of minnows native to North America's fresh waters than any other fish. Minnows can be hard to distinguish because many look alike.McClane, A.J. 1965. ''McClane's Field Guide to Freshwater Fishes of North America''. New York: Holt, Rinehart, and Winston. All minnows have one dorsal fin, ventral fins near the anus, a lateral line system (in most species), and smooth, round cycloid scales.Page, L.M. and Burr, B.M. 2011. ''Peterson Field Guide to Freshwater Fishes of North America North of Mexico''. Boston, New York: Houghton Mifflin Harcourt. Their jaws lack teeth, but they have one to three rows of pharyngeal teeth to grind food. Defining physical characteristics such as the number and type of fin rays, type of scales, and pattern of pharyngeal teeth are used to distinguish minnows. Silverjaw minnows have a head with a ...

Suckermouth Minnow
''Phenacobius'', the suckermouth minnows, is a genus of cyprinid fishes endemic to the United States. Historically the suckermouth minnow was not found as far eastward as Ohio, now they seem to be a stable species living throughout the Midwest and parts of southern states such as Texas, New Mexico, and Alabama. Many forests and prairies were cleared out to make farmland, this caused for drainage streams and rivers to take form, moving the minnows eastward. Originally the suckermouth minnows probably never crossed the Mississippi River prior to the developed farm land. They have a lifespan of roughly 3–5 years, but is hard to measure due to predation, survival rate of about 50 percent. There are currently five described species. Etymologically, "phenacobius" means "deceptive life", possibly because these species eat insects despite an herbivorous appearance. Species * ''Phenacobius catostomus'' D. S.
