生物学特性     字汇 (例如 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). 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).

栖息于外海礁石 (参考文献 9710) ,大陆架与外海岩石底部的拖网渔场。 (参考文献 30573) 稚鱼在沿海地区的泥质底部。 (参考文献 48635) 大部份捕食底栖无脊椎动物与小鱼。 (参考文献 30573) 可能的商业鱼如果充份的分枝能被设置.(参考文献 9775) 在市场上销售生鲜地了;(参考文献 9775) 有时有一种强而不愉快的滋味。 (参考文献 11888)
