Size / Weight / umur
Maturity: Lm ? range ? - ? cm
Max length : 21.5 cm TL jantan/; (Ref. 4983)
Duri punggung (Keseluruhan (total)): 16 - 18; duri punggung lunak (Keseluruhan (total)): 8-10; Duri dubur 3; Sirip dubur lunak: 7 - 8. Body deep and moderately compressed (Ref. 57075). Presence of a thick sensory canal on the six infraorbitals, with large openings that are widely separated from each other (Ref. 57075). Unicuspid outer and inner teeth on both jaws; outer teeth arranged in a single regular row; inner teeth smaller than outer teeth, arranged in three to six irregular rows on anterior part of upper jaw (Ref. 57075). Presence of 2 scale rows between upper and lower lateral lines (Ref. 57075). Scales ctenoid on flank; cheek scaled; dorsal and anal fins with scales at base; caudal fin with small scales anteriorly on fin membranes between rays; paired fins without scales (Ref. 57075). Upper lateral line high on body with 21-25 scales, lower lateral line running along body axis with 11-16 scales, two pored scales anteriorly on caudal fin (Ref. 57075).
The mouth is very protrusable which favor the idea of a planktonic diet (Ref. 7343).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.45 se; based on food items.
Daya lenting (Ref.
120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
