North Pacific: Kotzebue Sound to the northern Sea of Japan, Sea of Okhotsk and Akun Island in the Aleutian chain (Ref. 6793); and adjacent Arctic, including Gulf of Alaska (Ref. 51659).
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 21.6 cm SL male/unsexed; (Ref. )
Dorsal spines (total): 8 - 11; Dorsal soft rays (total): 6 - 9; Anal spines: 0; Anal soft rays: 13 - 16. Suprapectoral plates absent. Pectoral fin with 5 rows of blackish-brown spots.

Estimates based on models
Preferred temperature (Ref.
123201): -1.1 - 5.4, mean 1.9 °C (based on 531 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
