Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7 - 8; Dorsal soft rays (total): 10 - 11; Anal spines: 3; Anal soft rays: 7 - 8; Vertebrae: 24 - 26. 3 scale rows under the D2 origin down to the lateral line, 10-11 (rarely 12-13) in total. 14-15 pelvic fin rays, rarely 16.

Individuals 7.5 cm SL and longer mostly occur in the boreal areas, while those less than this the length occur in the tropical areas (Ref. 87004). Maximum length reported in Ref. 87004: 11 cm TL.

Estimates based on models

Preferred temperature (Ref. 123201): 1.7 - 18.6, mean 7.7 °C (based on 1396 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5176 [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): 3.4 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Fecundity assumed < 1000).

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