Family:  Cottidae (Sculpins)
Max. size:  7.73 cm SL (male/unsexed)
Environment:  benthopelagic; freshwater
Distribution:  North America: endemic to the Tallapoosa River drainage above the Fall Line in the east-central Alabama and west-central Georgia, USA.
Diagnosis:  Dorsal spines (total): 6-8; Dorsal soft rays (total): 14-18; Anal soft rays: 10-14; Vertebrae: 29-32. Diagnosed from all congeners except Cottus chattahoochee by the combination of the following characters: modally eight infraorbital canal pores; five bones in the suborbital series; reduced palatine teeth; a flexible spine and four rays in the pelvic fin; preoperculomandibular canals not fused at anterior rami of mandibles, with two pores at tip of chin; pectoral rays simple; preopercular armature well-developed with two or three spines; chin not mottled; and dorsal fins separate. Differs from Cottus chattahoochee by having the following features: usually incomplete lateral line (vs. complete); dermal prickling reduced or absent, when present generally restricted to a few scattered prickles in area along anterior part of lateral line (vs. a robust postpectoral patch in addition to prickles along the anterior lateral line); and narrow to moderately wide saddles (vs. moderate or wide) (Ref. 72414).
Biology:  Inhabits clean gravel or rocky bottomed streams with moderate to swift current. Frequently found in streams 3-15 m wide and at depths of 0.5-0.7 m (Ref. 72414). Feeds on anything alive which fits into its mouth (Ref. 72414).
