Bluntnose minnow
:''"Bluntnose minnows" is also used for the genus ''Pimephales'' as a whole.''
The bluntnose minnow (''Pimephales notatus)'' is a species of temperate freshwater fish belonging to the ''Pimephales'' genus of the cyprinid family. Its natural geographic range extends from the Great Lakes south along the Mississippi River basin to Louisiana, and east across the Midwestern United States to New York State. The bluntnose is very ubiquitous, and may be the most common freshwater fish in the Eastern U.S.〔Page, Lawrence M. and Brooks M. Burr (1991), ''Freshwater Fishes'', p. 129-130, Houghton Mifflin, New York, NY. ISBN 0-395-91091-9〕
==Description==
Bluntnose minnows are commonly long, with a maximum length of . On the first two or three dorsal rays are dark pigmented spots. The scales between the head and the dorsal fin are noted to be smaller than the rest of the scales on the body.〔(【引用サイトリンク】url=http://www.outdooralabama.com/fishing/freshwater/fish/other/minnow/bluntnose/ )〕 They have a rounded head and a terminal mouth, although the snout hangs a little bit over the mouth. The dark coloring on the edges of the scales cause a cross-hatched look along the body. The scales on these fish are cycloid scales, a type of leptoid scale. It is possible to find the age of a fish from the rings on the scales. The lateral line of a bluntnose minnow runs from its head to tail, ending in a black spot that makes them distinguishable from the fathead minnow.〔(【引用サイトリンク】url=http://www.dnr.state.oh.us/Home/species_a_to_z/SpeciesGuideIndex/bluntnoseminnow/tabid/6566/Default.aspx )〕 These minnows have a pale olive upper body (above the lateral line) and a silvery lower body (below the lateral line), with silvery-blue scales near the lateral line.
