Dorsal spines (total): 11 - 12; Dorsal soft rays (total): 20-22; Anal spines: 0; Anal soft rays: 14 - 19. Three zonal scale rows on body; a scale row of small ctenoid scales under the ventral scale row (Ref. 559). Four preopercular spines, the 2nd longest and simple, the 4th flattened; the first dorsal spine longer than the 2nd (Ref. 559).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Oviparous. Non-copulatory. However according to one study, presence of fertilized eggs in the ovary may have resulted from spermatozoa entering the ovary through the ovarian fluid during spawning, and consequently fertilizing unspawned eggs in the ovaries (Ref. 47168). Fertilized eggs in the ovary develop abnormally however, due to the unavailability of needed elements such as oxygen in the ovary (Ref. 47168).

Estimates based on models

Preferred temperature (Ref. 123201): 0.7 - 14.7, mean 3.9 °C (based on 374 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [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).
Trophic level (Ref. 69278):  3.6   ±0.1 se; based on diet studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (tm = 5-6).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100).
