背棘 (总数) : 2; 背的软条 (总数) : 7; 臀棘: 0; 臀鳍软条: 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).
有别于它的同类，除了截形的躯干中动脉碟系列的有管的碟 O. vestitus ， O. flexilis 与 O. affinis 以外，局限于前面的范围了.(对在后面的范围上有有管的碟) 与 O. vestitus 区分藉由在尾鳍上有虹膜膨囊 , 与藉由缺少成对的 W 形的标志。 有别于 O. flexilis ，而且 O. affinis 藉着具有侧面的中筛骨有大的子鼻骨薄板 (对小的子鼻骨薄板) ，排列成不的纵排重复急速拍打声 (对碟排列成纵排的重复图案) 的中央系列的 20-22个总侧骨板 (对 24个或更多) ，一个狭窄的颈背碟 (对一个宽的颈背碟) 与碟.(参考文献 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).
栖息于溶氧量高的，缓慢到中等的流动水域, 时常在河岸的附近.(参考文献 46820) 吃藻类。 (参考文献 46820)
