Usually inhabits rubble and gravel-bottomed pools and riffles of headwaters, creeks and small rivers, but can shift to other habitats depending on the environmental conditions and composition of fish communities. Where Cottus rhotheus and Cottus aleuticus do not occur, this species occupies riffles; at localities where all occur together, it shifts to pools (ref. 86798). Has been observed in slow moving and still waters with muddy substrates, but identification is uncertain (K. McAllister & M. Young, pers. comm. 07/04/20).

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=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Fec=432).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
