简单描述 型态特徵 | 形态测量图

背棘 (总数): 10; 背的软条 (总数): 12; 臀棘 3; 臀鳍软条: 7 - 8. Body pale brown dorsally with several vertical dark brown bars, becoming white ventrally; dorsal fin dusky with longitudinal yellow lines; pectoral, pelvic and anal fins dusky; caudal fin dusky with small yellow blotches (Ref. 13608). Preopercle has spines radiating from 2 centers (Ref. 26938).
身体白褐色背面有一些垂直的深褐色的横带, 变成腹侧白色; 背鳍暗色的有纵向的黄线; 胸鳍,腹鳍与臀鳍暗色的; 尾鳍暗色的有小黄色的斑块.(参考文献 13608) 前鳃盖骨有从 2 中心放射的棘。 (参考文献 26938)

生物学特性     字汇 (例如 epibenthic)

Inhabits bays, coastal grassy areas and shallow banks. Solitary (Ref. 26340) and retreats into shelter when frightened (Ref. 9710). Neither opercular spine nor anterolateral glandular grooves with venom gland is present (Ref. 57406). Synchronously hermaphroditic. Popular as a pan fish despite its small size.

栖息于海湾,海岸的长满草的区域与浅滩浅堆。 独居性 (参考文献 26340) 而且当被惊吓时撤退进入庇护所.(参考文献 9710) 没有一根鳃盖棘也不前外侧的腺凹槽用毒液腺存在.(参考文献 57406) 同步雌雄同体。 受欢迎的不在乎它的体型小作为一个食用鱼。
