背棘 (總數) : 0; 臀棘: 0; 臀鰭軟條: 56 - 62. Belly with 26 to 28 scutes. Lower jaw projecting, mouth pointing obliquely upward; no hypo-maxilla. Dorsal fin origin nearer to caudal fin base than to vertical from pectoral fin base by about 2 eye diameters (or behind midpoint of body by about 3 eye diameters); anal fin long, its origin much nearer to snout tip than to caudal fin base.

腹面有 26 到 28個鱗甲。 下頜突出的, 嘴朝向斜上方; 沒有皮下注射-顎骨。 背鰭起點較接近尾鰭基底超過到垂直的從胸鰭基底大約 2 眼直徑;(或身體的中點後面大約 3 眼直徑) 臀鰭長的, 它的起源很多超過到尾鰭基底較接近吻頂端。 鱗片容易地脫落。
Occurs in coastal waters, perhaps entering water with low salinities (Ref. 9336).
