Espinas dorsales (total) : 0; Espinas anales: 0; Vértebra: 145 - 159. Snout long; eye diameter 2-2.5 times in snout length; posterior nostrils much closer to eyes than to anterior nostrils; mouth very large; teeth generally large and conspicuous (Ref. 4832). Head broader, interorbital about 8 times in head; lateral-line pores before anus 44-47; dorsal-fin rays before anus 66-78; vertebrae 145-159 (Ref. 9830).
Body shape (shape guide): eel-like.
Occurs from the littoral zone to the upper bathy-benthic region (Ref. 9942, 11230). Inhabits soft bottoms (Ref. 11230), also found in estuaries. Sometimes enters freshwater environment (Ref. 9987). Feeds on small bottom fishes and crustaceans. Captured and cultured for fishery in Japan. Marketed mainly fresh (Ref. 7238). Also used as bait for shark fishing (Ref. 2872). Also caught by bag (dol) nets. Used in Chinese medicine (Ref. 12166).
