Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 6 - 8; Mjukstrålar i ryggfenan (totalt) : 15 - 18; Mjukstrålar i analfenan: 11 - 14; Ryggkotor: 29 - 32. Diagnosed from all congeners except Cottus tallapoosae 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 tallapoosae on the basis of dermal prickling well-developed, consisting of a postpectoral patch and prickles on the area immediately adjacent to the anterodorsal part of the lateral line (vs. prickles absent or reduced);
a complete lateral line (vs. usually incomplete); and moderate or wide saddles (vs. narrow or
moderate) (Ref. 72414).
Inhabits small streams with gravel or cobble substrate (Ref. 72414).
