簡短描述 檢索表 | 型態特徵 | 形態測量圖

A small-sized, deep-bodied species, sometimes with a slight nuchal hump (Ref. 35836). A stiff lower jaw, tapering towards a narrow, hypertrophied distal tip, covered with thick skin (Ref. 35836). The protruded mouth does not form a cylindrical tube (Ref. 35836). Long dorsal spine, 19-27% of SL (Ref. 35836). Anal and ventral fins are rather long, 19-24% and 18-21% of SL respectively, with a rather short pectoral-ventral length, 22-26% of SL (Ref. 35836). The caudal peduncle is deep, 11-12% of standard length (Ref. 35836). Scales: 12-14 predorsal scales (Ref. 35836). Live specimens are rather dark greenish brown, the back being darker, with usually greenish fins (Ref. 35836). In alcohol the basic color is a dull yellowish brown, the back being darker (Ref. 35836).
一種小的規模又身體縱深種, 有時有一個輕微的頸背隆起。 (參考文獻 35836) 一個硬的下頜, 尖端細的向狹窄 , 肥大的末端, 覆蓋著厚的皮膚.(參考文獻 35836) 被伸出的嘴不會形成一個圓筒形的管.(參考文獻 35836) 長的背棘,19-27% 的 SL.(參考文獻 35836) 臀鰭與腹鰭鰭是相當長的,19-24% 與 18-21% 的 SL 分別地, 具有一個相當短胸鰭-腹面的長度， 22-26% 的 SL.(參考文獻 35836) 尾梗是深的,11-12% 的標準長度.(參考文獻 35836) 鱗片: 12-14個前背的鱗片.(參考文獻 35836) 活體相當深色綠褐色的, 背部比較深色, 藉由通常呈綠色的鰭.(參考文獻 35836) 當保存在酒精中時基本的色彩是一個暗土黃色, 背部比較深色.(參考文獻 35836)

生物學特性     字彙 (例如 epibenthic)

Labeobarbus osseensis especially occurs near rocky substrates in water of less than 3 m deep (Ref. 35836). It feeds on adult insects and macrophytes (Ref. 35836).

Barbus osseensis 尤其在水生活於靠近岩石的底部少於 3 公尺深.(參考文獻 35836) 吃昆蟲成蟲與大型植物。 (參考文獻 35836)
