成熟度: Lm ?  range ? - 18 cm
Max length : 21.2 cm WD 雄魚/尚未辨別雌雄; (Ref. 114953); 23.4 cm WD (female)
Apparently benthic on soft bottoms near coast (Ref. 114953); inshore coastal habitats near mangroves, close to heavily human populated areas, thus making it accessible to fishers. Males mature at 17-18 cm WD while females at 18 cm WD. Size at birth 5-9 cm WD (Ref. 130662). Caught by trammel nets (Ref. 114953).
