生物学特性     字汇 (例如 epibenthic)

Adults occur in lagoon and seaward reefs with hard substrate; young abundant in tide pools (Ref. 3145, 48637). Benthopelagic (Ref. 58302). Often feeding near freshwater run-offs where certain algae grow on rocks that are grazed (Ref. 48637). Occasionally form schools; feed on filamentous algae in large aggregations. During spawning, clouds of eggs and sperm are preyed upon by eagle rays which are often present during spawning. Form spawning aggregations (Ref. 27825). Size of metamorphosis from post-larva stage to juvenile is 3.2 cm (Ref. 9267). Utilized as a food fish (Ref. 7364). Minimum depth reported taken from Ref. 27115.

出现在舄湖与临海礁石,有坚硬的底部; 幼鱼丰富的在潮池中.(参考文献 3145,48637) 时常摄取食物的特定藻类长在岩石上的近的淡水溢流那是啃食.(参考文献 48637) 偶然地形成鱼群; 较大时吃丝状的藻类群集。 在产卵的时候,大量的卵与精子被鹰魟捕食时常那是在产卵期间出现。 形成产卵群集。 (参考文献 27825) 从后幼生期到稚鱼的锐变的大小是 3.2 公分。 (参考文献 9267) 作为食用鱼.(参考文献 7364) 最小深度报告取自参考文献 27115.
