Espinas dorsales (total) : 7 - 9; Radios blandos dorsales (total) : 15 - 18; Radios blandos anales: 11 - 14.

Inhabits rubble and gravel riffles of rivers and rocky lake shores. Individuals up to 5 cm feed on planktonic crustaceans and aquatic insect larvae especially that of midges and mayflies (Ref. 1998). Larger sculpins feed on minnows and other fishes (Ref. 1998). Possibly spawns in June (Ref. 1998).

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).

Nivel trófico (Ref. 69278): 3.4 ±0.45 se; based on food items.

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Fec=448).

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