简单描述
检索表 | 型态特徵 | 形态测量图
背的软条 (总数) : 42 - 44; 臀鳍软条: 33 - 35; 脊椎骨: 47. The juvenile holotype of this species is distinguished by the following characters: vertebrae 47; dorsal-fin rays 42-44; no coronal pore; vertical mouth, symphysis of upper jaw above level of eye; body not humpbacked; vertebral column not curved behind cranium; enlarged gill cavity; anus on vertical behind head; notched pectoral fin, rays 8+2+5-6; eye 17-19% HL (Ref. 53592).
Body shape (shape guide): elongated; Cross section: oval.
The species possess a very large superior mouth with vertical jaws, eyes located close to the dorsal contour of the head and oriented to look forward and up, and a straight body, suggesting an adaptation to feeding on detritus and animals (such as copepods) above it in the water column (Ref. 53592).
