簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 2; 背的軟條 (總數) : 7; 臀棘: 0; 臀鰭軟條: 6. Differs from its congeners, except O. vestitus, O. flexilis, and O. affinis by canal-bearing plates of trunk median plate series truncated, restricted to the anterior field (versus presence of canal-bearing plates on posterior field). Distinguished from O. vestitus by the presence of iris diverticulus, and by the absence of paired W-shaped marks on caudal fin. Differs from O. flexilis and O. affinis by having lateral ethmoid with large subnasal lamina (versus small subnasal lamina), 20-22 total lateral plates (versus 24 or more), a narrow nuchal plate (versus a wide nuchal plate), and plates of median series not arranged in tandem repeat patter (versus plates arranged in tandem repeat pattern) (Ref. 46820).
有別於它的同類，除了截形的軀幹中動脈碟系列的有管的碟 O. vestitus ， O. flexilis 與 O. affinis 以外，侷限於前面的範圍了.(對在後面的範圍上有有管的碟) 與 O. vestitus 區分藉由在尾鰭上有虹膜膨囊 , 與藉由缺少成對的 W 形的標誌。 有別於 O. flexilis ，而且 O. affinis 藉著具有側面的中篩骨有大的子鼻骨薄板 (對小的子鼻骨薄板) ，排列成不的縱排重複急速拍打聲 (對碟排列成縱排的重複圖案) 的中央系列的 20-22個總側骨板 (對 24個或更多) ，一個狹窄的頸背碟 (對一個寬的頸背碟) 與碟.(參考文獻 46820)
Facultative air-breathing in the genus (Ref. 126274); Inhabits well-oxygenated, slow to moderate flowing waters, often near river banks (Ref. 46820). Feeds on algae (Ref. 46820).
棲息於溶氧量高的，緩慢到中等的流動水域, 時常在河岸的附近.(參考文獻 46820) 吃藻類。 (參考文獻 46820)

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=0.00851 (0.00374 - 0.01935), b=3.09 (2.90 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 2.0 ±0.00 se; based on food items.
Fishing Vulnerability (Ref.
