Usually found in shallow water (less than 10 m), however, Kyushin et al. (1977, Ref. 6894) reported specimens caught on a vertical longline at depths of 45 to 62 m. Solitary or in small groups. Often drifts well above the bottom (Ref. 9710). Feeds exclusively on fishes (parrotfishes, wrasses, holocentrids, acanthurids, a triggerfish, and a juvenile Sphyraena) (Ref. 6448). Also caught with trawls.
