Etymology: Cottus: Greek, kottos = a fish (Ref. 45335); tallapoosae: The specific name is in reference to the Tallapoosa River, to which this species is endemic. Tallapoosa is an ancient Upper Creek American Indian settlement on the river; originally derived from the Choctaw 'pulverized rock'.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Subtropical
North America: endemic to the Tallapoosa River drainage above the Fall Line in the east-central Alabama and west-central Georgia, USA.

Morphology | Morphometrics
(total): 6 - 8;
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).
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).
