Biologie     Glossaire (ex. epibenthic)

Lives close to or on the bottom of the upper continental slope. Prefers hard substrates. Young specimens feed on small shrimps and fish (Ref. 4784). A deep sea species, nonetheless, the young are often found near the coast (Ref. 9137). Utilized as fishmeal and source of oil in eastern central Atlantic (Ref. 3695).
