大小 / 重量 / 年齡
Maturity: Lm ?  range ? - ? cm
Max length : 29.3 cm TL 雄魚/尚未辨別雌雄; (Ref. 71685); common length : 25.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5217)
背棘 (總數): 0; 背的軟條 (總數): 11-12; 臀棘 0; 臀鰭軟條: 11. Body except for snout, pectoral base and caudal peduncle covered with prickles; teeth fused into plates, two plates on each jaw; nostril with two openings; body dark green dorsally with six transverse black bars, white ventrally; fins dusky green or dark brown (Ref. 13608).
Solitary or in groups of 2 or 3 individuals but never in schools (Ref. 35237). Inhabits shallow inshore waters usually on soft bottoms. Frequently found in freshwater (Ref. 13608). When threatened, it becomes inflated like a balloon, in order to ward off predators. Carnivorous, feeding mainly on mollusks which crushes with its powerful teeth (Ref. 35237). Of negligible commercial importance and usually not marketed (Ref. 5217).
