An offshore species found mainly around coral reefs. Generally solitary or occur in small schools of six or less. Preys on small schooling fishes such as Decapterus, Caesio, Nasio, Cirrhilabrus, Pterocaesio and squids. Caught mainly by pole-and-line. Marketed canned and frozen (Ref. 9684, 48637). Adults may be ciguatoxic (Ref. 37816). Minimum depth reported taken from Ref. 128797.
一个外海种主要地珊瑚礁的周围发现。 通常独居性的或六以内形成小群鱼群。 捕食小的群游性鱼例如 Decapterus ， Caesio ， Nasio ， Cirrhilabrus ， Pterocaesio 与乌贼。 在市场上销售罐装及冷冻.(参考文献 9684,48637) 成鱼可能具有热带海鱼毒.(参考文献 37816)
