Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 42 - 44; Raggi anali molli: 33 - 35; Vertebre: 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).
