|Distribution||USA (N Alabama)|
Type locality: "Mulberry Fork of the Black Warrior River, 9 miles east of Jasper, Walker County, Alabama, near the bridge crossing of U.S. Highway 78".
|Types||Holotype: LSUM 109567 (was: TU 16171 at Tulane University)|
|Diagnosis||Morphologically, S. depressus can be diagnosed from all other species of Sternotherus by this combination of characteristics: a round low carapace with flared margins that may possess a single low keel in young animals (but lateral keels are lacking), reticulate pattern of lines on the head and neck, and a single pair of neck barbels. There is evidence of introgression between S. depressus and S. peltifer in this, and other work (e.g. Scott and Rissler 2015). and hybrids between these two species may be found in the North River drainage of the Black Warrior River (Scott et al. 2017).|
|Comment||Habitat: freshwater (swamps, quiet rivers)|
Hybridization: Sternotherus depressus and S. minor hybridize (Scott et al. 2017). In fact, S. depressus is nested within S. minor
