Rayons mous dorsaux (Total) : 11 - 14; Rayons mous anaux: 8 - 10; Vertèbres: 42 - 44. This species is characterized by the following: D 11-14 (usually 12-13); A 8-10; P I,14-16; predorsal scales 25-30 (usually 25-28); number of scales in an oblique (antrorse) row between the origin of the dorsal fin and the lateral line 8½-10 (usually 8½); total number of gill rakers on the first arch 22-24 (6-7 + 16-17); total number of vertebrae 42-44 (26-28 + 15-16); snout short and deep; upper jaw rounded at tip; lower jaw usually shorter than upper jaw or of equal size, rarely slightly longer; jaw teeth numerous, rather large (usually clearly visible with the naked eye), tricuspid, but some fish also with few conical teeth and arranged in 3-4 rows; palatine teeth numerous (Ref. 130199).
Body shape (shape guide): elongated; Cross section: circular.
Females of this species (17.9-18.8 cm SL) that were captured on 12 January 1988 at 20°01’S 115°00’E were close to maturity. Juveniles are unknown (Ref. 130199).
