Biology     Glossary (e.g. epibenthic)

Juveniles are found from near surface to about 250 m to more than 1,000 m (Ref. 6536). Largest adults may be benthopelagic (Ref. 9851). Adults are plankton-eaters like the other members of the family (Ref. 6744). Oviparous, with planktonic larvae (Ref. 36622).
