🐟 Physical Description

Dorsal spines (total): 7 - 9; Dorsal soft rays (total): 17 - 20; Anal soft rays: 13 - 15. Distinguished from all congeners in the upper Columbia River basin by the lack of a second preopercular spine, palatine tooth patches smaller and separate from the vomerine tooth patch, and axillary prickling. Differs from Cottus cognatus, C. confusus , C. hubbsi, and C. rhotheus by the absence of a second preopercular spine; and from C. cf. bairdii and C. beldingii by the presence of axillary prickling. Furthermore, this species possesses palatine tooth patches smaller than the vomerine tooth patch and the patches are separated (vs. palatine tooth patches equal to or larger in size than the vomerine tooth patch in Cottus cf. bairdii; and generally, palatine teeth absent in Cottus beldingii) .
