Etymology: Etheostoma: Greek, etheo = to strain + Greek, stoma = mouth; Rafinesque said "various mouths", but Jordan and Evermann suggest the name might have been intended as "Heterostoma (Ref. 45335); jordani: Named after David Starr Jordan, an eminent ichthyologist (Ref. 10294).

Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Temperate; 35°N - 32°N
North America: found only in Alabama and Black Warrior River systems (in Mobile Bay drainage) in Georgia, Alabama and southeastern Tennessee, USA.

Maturity: Lm ?  range ? - ? cm
Max length : 7.9 cm TL male/unsexed; (Ref. 5723); common length : 5.0 cm TL male/unsexed; (Ref. 12193)
Inhabit fast rocky riffles of creeks and small to medium rivers (Ref. 33799); also found in medium to large streams (Ref. 10294). Adults occur in the deepest portions of riffles with moderately strong current. Prey mainly on insects (midge and other dipteran larvae, mayfly nymphs, and smaller quantities of water mites and caddisfly larvae (Ref. 10294)). Feed by pecking small prey from the surface of rocks (Ref. 33799).
