Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 54 - 58; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 37 - 50. Dorsal fin extending about halfway along length of caudal fin; caudal narrow, slightly rounded; lower 6 rays of pectorals slightly thickened and completely exserted, the next 5 greatly to moderately exserted and longer than the rays immediately above them, no real notch in fin; pelvic fins modified to form a small adhesive disc with a thickened margin, placed far forward, below eye (Ref. 6885). Off-white to pale rose on body; ends of pectoral and edges of posterior parts of dorsal and anal, and most of the caudal, black; lining of mouth and gill cavity, and tongue black (Ref. 6885).
Body shape (shape guide): elongated.
Found on mud bottoms (Ref. 2850). Possibly the most commonly captured liparid below 200 m; captured frequently by fishers (Ref. 26773). Known to feed on polychaete worms, small crustaceans, tiny clams and other invertebrates (Ref. 4525).
