生物學特性     字彙 (例如 附生動物)

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).

生命週期和交配行為 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

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).
