Inhabits offshore reefs (Ref. 9710), trawling grounds of the continental shelves and offshore rocky bottoms (Ref. 30573). Juveniles inshore on muddy substrates (Ref. 48635). Solitary or in small groups (Ref. 90102). Feeds mostly on bottom invertebrates and small fishes (Ref. 30573). Potential commercial fish if sufficient stocks can be located (Ref. 9775). Marketed fresh (Ref. 9775); sometimes with a strong and unpleasant flavor (Ref. 11888).
