生物學特性     字彙 (例如 epibenthic)

Inhabits coral-rich areas of outer reef slopes and drop-offs to depths greater than 40 m (Ref. 9710). Hides in caves or beneath ledges by day; forage for food at night, mainly on benthic crabs and shrimps. Spine of preopercle venomous.

棲息於外礁斜坡與海峭壁到深度大於 40 公尺的珊瑚礁繁盛區域。 (參考文獻 9710) 躲在洞穴中或在岩架之下白天; 覓食在晚上, 主要吃底棲的螃蟹與蝦。 前鰓蓋骨的棘有毒的。
