Maturity: Lm ?  range ? - ? cm
Max length : 46.0 cm TL male/unsexed; (Ref. 7251); max. reported age: 11 years (Ref. 72462)
Commonly found in harbors and shallow coastal waters. Move to deeper water in winter. Adults attach their eggs near the base of a sponge to use as a spawning bed (Ref. 34819, 41075). Benthic; feeds on crustaceans, molluscs, sea squirts, squids and fishes (herring, mackerel, smelt, sand lance and silversides (Ref. 5951)) (Ref. 58426).

Estimates based on models
Preferred temperature (Ref. 115969
): 0.9 - 12.8, mean 6.7 °C (based on 204 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00298 - 0.01684), b=3.13 (2.93 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.2 se; based on diet studies.
Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (24 of 100) .
