Sturgeon chub

The type species was collected in the Milk River in Montana, and described by Charles Frédéric Girard in 1856. Girard named it Gobio gelidus, but it was reclassified as Hybopsis gelidus in 1900 and Macrhybopsis gelidus in 1935. A new classification of Hybopsis gelida was suggested in 1965. ==Description and habitat==

The sturgeon chub is slender, streamlined fish with a long, flat snout. There is a small barbel near the corner of the mouth, and small pustules on the throat. The fish's color ranges from silvery-white on the belly to silvery sides, with a light-brown back. The tail is deeply forked, with the lower lobe darker than the upper lobe. The last dorsal fin ray extends beyond the first ray of the depressed fin. although it does have teeth in its throat. It lives in waters which are little populated by other small fish, but can be found associating with the flathead chub, sicklefin chub, and speckled chub. The habitat of the sturgeon chub is murky river bottoms in fast-flowing streams with gravel bottoms. ==References==
