Editing Quillback (section)

==Distribution, habitat and diet==
The quillback is found throughout much of North America, from [[Saskatchewan]] to [[Florida]], and from [[South Dakota]] to [[Alabama]]. The quillback occupies temperate, freshwater habitats. This includes many streams, lakes, channels and rivers. They prefer water that is clear, slow moving, highly productive and moderately deep. The quillback can commonly be found in the [[Hudson Bay]], the [[Mississippi River]] basin, the [[Great Lakes]], and drainages from the [[Delaware River|Delaware]], [[Apalachicola River|Apalachicola]], and [[Pearl River (Mississippi–Louisiana)|Pearl]] rivers.<ref>{{cite news |url=http://gfp.sd.gov/wildlife/critters/fish/rare-fish/quillback-sucker.aspx |title=Quillback Sucker |work=South Dakota Game, Fish and Parks |date=2010 |access-date=2015-05-07 }}</ref> They often comprise a large portion of the biomass of warmwater rivers, but they are very difficult to catch with traditional American angling methods.<ref name="roughfish">[http://www.roughfish.com/content/view/46/128/ roughfish.com – Quillback carpsucker] {{webarchive |url=https://web.archive.org/web/20110715211409/http://www.roughfish.com/content/view/46/128/ |date=July 15, 2011 }}</ref> The quillback is closely related to the [[highfin carpsucker]] and the [[river carpsucker]].  All three species are rarely caught by anglers due to their feeding habits, but they have been caught occasionally on worms, minnows, and artificial lures.{{Citation needed|date=March 2021}}

Quillbacks usually feed in [[School (fish)|schools]]. They are [[omnivore]]s and bottom feeders that prefer lakes, rivers and streams in which the water is clear at the bottom. The school of quillbacks moves slowly over a sand or gravel bottom when they eat. Their typical diet consists of aquatic insect larvae and other small organisms although they have also been known to eat [[Mollusca|molluscs]] and [[aquatic vegetation]].<ref>{{Cite book |last=Steiner |first=Linda |title=Pennsylvania Fishes |publisher=Pennsylvania Fish & Boat Commission |date=September 2013 |isbn=978-1-930369-01-6 |edition=4th |location=United States of America |pages=75–76}}</ref>
