At 12-15 cm TL, semi-pelagic juveniles become demersal at 150-400 m depth (Ref. 55957). Adults migrate to deeper habitats at depths greater than 1,000 m (Ref. 55957). Utilized as food fish (Ref. 4931).
在 12-15 公分TL, 半大洋性稚鱼在 150-400 公尺深变成底栖.(参考文献 55957) 成鱼在深度大于 1,000 公尺回游到较深的栖息地。 (参考文献 55957) 作为食用鱼了。 (参考文献 4931)
