Inhabits oceanic and neritic waters (Ref. 26340). Feeds on small fishes. Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205). Although sold fresh and salted, its market is limited due to the green-colored flesh (Ref. 5217). Circumglobal in tropical seas and divisible into four subspecies (Ref 90102).
