Length at first maturity / Size / Vikt / Age
Maturity: Lm 6.2 range ? - ? cm
Max length : 20.0 cm TL hane/ej könsbestämd; (Ref. 1371)
Mjukstrålar i ryggfenan (totalt) : 48 - 51; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 41 - 43. Head relatively large, less than five times in SL. Skin fold above the upper lip with three pairs of lobes or small barbels. First fin ray followed by a row of small, fleshy filaments (Ref. 1371). One barbel on the lower jaw and four on the snout (Ref. 35388).
Found in the sublittoral zone, on sand or mud bottoms. Feed mostly on decapod crustaceans, lobsters, crabs, mysids and polychaetes (Ref. 3663). Oviparous (Ref. 205). Spawning may take place in deeper waters (Ref. 57987).
Probably pairs up during breeding (Ref. 205).
