Males are slightly larger than females and are brightly colored when breeding.[2][3] Distribution and habitatThe Yazoo darter inhabits small, clear, mostly spring-fed streams with substrates that include clay, sand, gravel, or silt. Its range encompasses headwater streams in the Little Tallahatchie River's watershed, including the Tippah River and Cypress Creek, and the Yocona River watershed, including Otoucalofa Creek. The range includes Benton, Calhoun, Lafayette, Marshall, Tate, Tippah, Union, and Yalobusha counties and parts of Holly Springs National Forest.[4] Based on mitochondrial DNA, it has been determined that there are two monophyletic clades, those in the Little Tallahatchie River and those in the Yocona River drainages.[5] BehaviorMost individuals do not survive past their first year, and few individuals survive more than two years.[4] Individuals primarily eat insects.[3] StatusStream channelization and urbanization, particularly culverts have led to range restriction and declining populations of the Yazoo darter.[4] The species is listed as near-threatened by the International Union for Conservation of Nature, sensitive by the United States Forest Service, globally imperiled by The Nature Conservancy, and vulnerable by the Southeastern Fisheries Council and American Fisheries Society.[4]References{{Commons category|Etheostoma raneyi}}1. ^1 {{Cite journal | author = NatureServe | title = Etheostoma raneyi | journal = The IUCN Red List of Threatened Species | volume = 2014 | page = e.T202524A18229709 | publisher = IUCN | date = 2014 | url = http://www.iucnredlist.org/details/202524/0 | doi = 10.2305/IUCN.UK.2014-3.RLTS.T202524A18229709.en | access-date = 15 January 2018}} {{Taxonbar|from=Q3758732}}2. ^{{cite journal |first1=Carol E |last1=Johnston |first2=Wendell R |last2=Haag |title=Life history of the Yazoo darter (Percidae: Etheostoma raneyi), a species endemic to north-central Mississippi |journal=Tulane Studies in Zoology and Botany |volume=30 |pages=47–60 |year=1996 |url=http://www.srs.fs.usda.gov/pubs/ja/ja_johnston001.pdf}} 3. ^1 {{cite journal |first1=Ken A |last1=Sterling |first2=Melvin L |last2=Warren Jr |first3=L Gayle |last3=Henderson |title=Conservation assessment of the Yazoo darter (Etheostoma raneyi) |journal=Southeastern Naturalist |volume=12 |issue=4 |pages=816–842 |year=2013 |url=http://www.srs.fs.usda.gov/pubs/ja/2014/ja_2014_warren_002.pdf |doi=10.1656/058.012.0429}} 4. ^1 2 3 {{cite document |title=Yazoo Darter (Etheostoma raneyi) |publisher=U.S. Forest Service |date=January 2012 |accessdate=June 23, 2015 |url=http://www.srs.fs.usda.gov/cbhr/products/factsheets/CBHRFactSheet_2012_001.pdf}} 5. ^{{cite journal |first1=Steven L |last1=Powers |first2=Melvin L |last2=Warren Jr |year=2009 |title=Phylogeography of three snubnose darters (Percidae: Subgenus Ulocentra) endemic to the southeastern US Coastal Plain |journal=Copeia |volume=2009 |pages=523–528 |url=http://pubag.nal.usda.gov/pubag/downloadPDF.xhtml?id=40735&content=PDF |doi=10.1643/ci-08-047}} 3 : Natural history of Mississippi|Etheostoma|Fish described in 1994 |
