簡短描述
檢索表 | 型態特徵 | 形態測量圖
Can be distinguished from all other species in the genus except G. grammepareius by retaining a dark stripe from the eye to the corner of the preopercle as adult. Differs from G. grammepareius by (1) a scaly sheath extending almost the entire length of the dorsal fin base, (2) few and indistinct light spots on the caudal fin, (3) faint , horizontal stripes along the side, (4) narrower lips, (5) microbranchio-spines externally on second to fourth gill arches, and (6) higher meristics: modally D. XVII. 11 instead of XVI.ll, E1 row scales 32 instead of 30 I , and vertebrae modally 14+ 18 instead of I 14+17 (Ref. 57764).
藉由保有一條深色的斑紋從眼睛到前鰓蓋骨的角落當成魚時能除了 G. grammepareius 以外的本屬中被與所有的其他種區分。 有別於鱗鞘幾乎延伸背鰭基底 (2)的整個長度的 G. grammepareius(1), 在尾鰭 (3)上的很少而不明顯的淡色斑點, 模糊又水平的斑紋沿著側邊 (4)，較狹窄的唇 (5)， microbranchio-棘在第二個外部地對第四個鰓弓 , 與 (6) 較高的身體分節: 典型地 D. XVII。 11 取代 XVI.ll, E1 列鱗片 32 取代 30個 I, 與脊椎骨典型地 14+18 取代 I 14+17.(參考文獻 57764)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.00850 - 0.04473), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
營養階層 (Ref.
69278): 2.4 ±0.1 se; based on size and trophs of closest relatives
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
