Längd vid första mognad / Storlek / Vikt / Ålder
Könsmognad: Lm 8.8, range 7 - 9 cm Max length : 114 cm TL hane/ej könsbestämd; (Ref. 81053); common length : 25.0 cm TL hane/ej könsbestämd; (Ref. 4); publicerad maxvikt: 1.7 kg (Ref. 81053)
Benthic in coastal and shelf waters (Ref. 4'>106894). Possibly a selective feeder, preying mainly on crabs, echinoderms, mussels and polychaetes but also ingesting algae and seaweeds, with a complex foraging behavior and thus capable of maintaining gross diet composition despite of sharp variations in prey availability, seasonality and ontogenetic changes, e.g., molt- and size-related diet shifts (Ref. 4'>33024). Migration does not occur, or only to a limited scale (Ref. 4).
