Länge bei der ersten Reifung / Größe / Gewicht / Alter
Geschlechtsreife: Lm 8.8, range 7 - 9 cm Max length : 114 cm TL Männchen/unbestimmt; (Ref. 81053); common length : 25.0 cm TL Männchen/unbestimmt; (Ref. 4); max. veröff. 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).
Lebenszyklus und Paarungsverhalten

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).
