生物学特性     字汇 (例如 epibenthic)

Abundant in shallow coastal areas, especially in rocky coasts with macroalgae. May be solitary or swim in loose schools (Ref. 5227). Feeds by scraping or breaking off chunks of the reef and digest the algae that grows within, or they feed directly on algae (Ref. 28023).

丰富的在水浅的沿岸区域中, 尤其在岩石的海岸中以大型藻类。 可能是独居性或者在松散的鱼群中游泳。 (参考文献 5227) 刮食或者打破外海的大块礁而且消化在里面生长的藻类, 或直接吃藻类.(参考文献 28023)
