Global Range: (250-1000 square km (about 100-400 square miles)) The fuzzy pigtoe is endemic to and still extant in the Escambia, Pea, and Choctawhatchee rivers in Alabama and Florida, and the Yellow River in Alabama (Mirarchi et al., 2004; Williams et al., 2008; Gangloff and Hartfield, 2009). Due to recent status surveys the historical range of the fuzzy pigtoe has been expanded (Williams et al., 2000; Blalock-Herod et al., 2005). Within the Escambia River drainage, the fuzzy pigtoe has been found in the Escambia River, Escambia and Santa Rosa Counties, Florida; Conecuh River, Escambia, Covington, Crenshaw, and Pike Counties, Alabama; Murder, Sandy, and Burnt Corn Creeks, Conecuh County, Alabama; Sepulga River, Conecuh County, Alabama; Pigeon Creek, Covington County, Alabama; Patsaliga and Little Patsaliga Creeks, Crenshaw County, Alabama; and Mill Creek, Pike County, Alabama. Within the Yellow River drainage, the fuzzy pigtoe is known from the Yellow River, Covington County, Alabama. Within the Choctawhatchee River drainage, the fuzzy pigtoe was known from Choctawhatchee River, Washington, Walton, and Holmes Counties, Florida; Limestone Creek, Walton County, Florida; Wrights Creek, Holmes County, Florida; Holmes Creek, Washington County, Florida; Choctawhatchee River, Geneva and Dale Counties, Alabama; Little Choctawhatchee River, Dale and Houston Counties, Alabama; Panther Creek, Houston County, Alabama; West Fork Choctawhatchee River, Dale and Barbour Counties, Alabama; East Fork Choctawhatchee River, Henry County, Alabama; and Pea River, Geneva, Dale, and Coffee Counties, Alabama (Williams et al., 2000; Blalock-Herod et al., 2005) (see USFWS, 2003). Blalock-Herod et al. (2005) listed this species from 21 historical sites in the Choctawhatchee River drainage, relocated it at 6 and found it at 34 new sites scattered in the upper and lower portions of the river in Alabama and Florida.
