Lengte bij maturiteit / Grootte / Gewicht / Leeftijd
Maturiteit: Lm 8.8, range 7 - 9 cm Max length : 114 cm TL mannelijk / geslacht onbekend; (Ref. 81053); common length : 25.0 cm TL mannelijk / geslacht onbekend; (Ref. 4); max. gepubliceerd gewicht: 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).

The females carry their eggs for 10 to 11 months, ovigerous females are found throughout the year (Ref. 4). 0.5 broods per year (Ref. 81148); 0.15 cm postlarval size (Ref. 81158); 1 month pelagic period (Ref. 81159).
