Taggstrålar i ryggfenan (totalt) : 10 - 11; Mjukstrålar i ryggfenan (totalt) : 25 - 32; Taggstrålar i analfenan: 2; Mjukstrålar i analfenan: 9 - 10. Body silvery (Ref. 4373).
Body shape (shape guide): fusiform / normal.
Found in coastal waters, over sand muddy bottom. Juveniles enter estuaries. Adults feed on pelagic fishes at night. Often caught with Umbrina canariensis. Feeds on pelagic fish such as mackerel and horse mackerel (Ref. 36731). Marketed fresh, flesh highly esteemed (Ref. 9772).
