Description
Bluntnose minnows are commonly 6.5 cm (2.5 in) long, with a maximum length of 11 cm (4.3 in). 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. 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. 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.

Famous quotes containing the word description:
“He hath achieved a maid
That paragons description and wild fame;
One that excels the quirks of blazoning pens.”
—William Shakespeare (1564–1616)
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
