Max length : 120 cm TL mannelijk / geslacht onbekend; (Ref. 7251); common length : 90.0 cm TL mannelijk / geslacht onbekend; (Ref. 3787); max. gepubliceerd gewicht: 22.6 kg (Ref. 40637); max. gerapporteerde leeftijd: 30 Jaren (Ref. 796)
Inhabits continental shelf, occurring deeper in southern parts of range (Ref 7251); tolerating a wide range of temperature (0-21°C) (Ref. 5951).
That testes seem to develop earlier and stay ripe longer suggest multiple spawning by males. Eggs are laid in long, ribbon-shaped veils (Ref. 4842).

Estimates based on models
Preferred temperature (Ref.
123201): 0.6 - 9.9, mean 5 °C (based on 189 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01380 (0.01040 - 0.01833), b=2.98 (2.90 - 3.06), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trofisch niveau (Ref.
