The rusty crayfish (Faxonius rusticus) is a large, aggressive species of freshwater crayfish which is native to the United States, in the Ohio River Basin in parts of Ohio, Kentucky, and Indiana.[2][4][5] Its range is rapidly expanding across much of eastern North America, displacing native crayfishes in the process.[6][7] The rusty crayfish was first captured in Illinois in 1973, and has been collected at over 20 locations in the northern portion of the state.[8] In 2005, F. rusticus was found for the first time west of the Continental Divide, in the John Day River, Oregon, which runs into the Columbia River.[9]
