簡短描述
檢索表 | 型態特徵 | 形態測量圖
Body extremely slender. Dorsal and ventral coloration sharply contrasted; fine dark horizontal lines forming series of fine dots and dashes on upper half of body; a dark ventral saddle near middle of caudal peduncle. Head relatively short (usually < 21% TL). Caudal peduncle very elongate (usually > 23% TL). Eyes rather narrow; upper eyelid with pale naked patch. Denticles extremely dense, bristle-like, not arranged in defined rows. Flank-marking base forward of second dorsal-fin spine; its posterior branch longer than anterior branch and extending beyond free rear tip of second dorsal fin; central caudal marking absent. Monospondylous centra 41-45 (Ref. 45056).
身體非常細長。 背部與腹的顏色銳利地對比; 在身體的上半部上的深色細的水平線形成數列細點與破折線; 在尾柄的中央附近的一個深色的腹鞍狀斑。 頭部相當短的.(通常 <21% TL) 尾柄非常長的.(通常 >23% TL) 眼相當狹窄; 上眼瞼有灰白的裸露區塊。 細齒非常密集﹐像剛毛一樣的, 不排列成固定的列。 側面的斑紋基底第二背鰭-鰭棘向前; 它的在後部分支長度超過前面的分支而且延伸超過第二背鰭鰭的鰭游離後端; 中央的尾鰭斑紋不存在。 Monospondylous 中心 41-45.(參考文獻 45056)
