Maturity: Lm ?  range ? - ? cm
Max length : 9.0 cm SL male/unsexed; (Ref. 83416)

Short description Morphology | Morphometrics

Dorsal spines (total): 7 - 9; Dorsal soft rays (total): 15-19; Anal soft rays: 12 - 14. Distinguished from all other congeners, except Cottus hypselurus and Cottus caeruleomentum, by the blue chin and belly on spawning males. Differs from Cottus hypselurus by dorsal fin spines 8-9 (versus 6-7); pectoral fin rays 16-17 (versus 13-15); pigmentation of the ventral surface of the peritoneum weak (versus moderate to strong ); dorsal-fin union moderate to wide versus slight to moderate. Can be differentiated from Cottus caeruleomentum by caudal base band notched (versus non-notched); dorsal fins moderately to widely connected (versus slightly connected); pectoral fin rays 16-17 (versus 12-15); ventral surface of peritoneum weakly pigmented (versus moderately to strongly pigmented) (Ref. 83416).

Biology     Glossary (e.g. epibenthic)

Found in cool to cold spring-fed creeks and rivers with cobble bottoms (Ref. 83416).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
