Taggstrålar i ryggfenan (totalt) : 10 - 11; Mjukstrålar i ryggfenan (totalt) : 13 - 15; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 13 - 15.
Gregarious. Inhabits the upper portion of the continental shelf from the coastline to 100 m depth, but especially from 30 to 50 m. Occurs on various types of bottom. Sometimes forms sizeable aggregations. Feeds on small benthic mollusks and crustaceans (Ref. 4781). Important food fish. Minimum depth range from Ref. 113561.
