Morphology | Morphometrics
Larvae are pelagic (Ref. 27121, Ref. 36731), while adults live close to the sea bed (Ref. 36731). Adults feed on worms, crustaceans, mollusks, and fish (Ref. 27121, Ref. 36731). Utilized as a food fish (Ref. 4931).

Estimates based on models
Preferred temperature (Ref. 115969
): 9.2 - 11.9, mean 10.4 °C (based on 37 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00460 - 0.02076), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.45 se; based on food items.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (K=0.07).
Vulnerability (Ref. 59153
