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

Inhabits offshore reefs (Ref. 9710), trawling grounds of the continental shelves and offshore rocky bottoms (Ref. 30573). Juveniles inshore on muddy substrates (Ref. 48635).

Marketed fresh (Ref. 9775); sometimes with a strong and unpleasant flavor (Ref. 11888).
