Taggstrålar i ryggfenan (totalt) : 15 - 17; Mjukstrålar i ryggfenan (totalt) : 10 - 13; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 9 - 10. Diagnosis: low number of gill-rakers (15-18) (Ref. 55925).
Occurs in shallower part of the sandy shores but also found at levels below 30m (Ref. 5595), and frequents muddy/soft bottoms (Ref. 5595, 55925), but also found over rocky habitat (Ref. 55925). Feeds mainly on small benthic invertebrates (Ref. 267). Scoops up large amounts of silty sediment from the sand; commonly observed in small groups of about 5 individuals, but also forages in large schools (Ref. 55925).
