Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

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).

May spawn for the first time from around 8-10 years of age (Ref. 71843).
