Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 2; Dorsale zachte stralen (totaal) : 7; Anale stekels: 0; Anale zachte stralen: 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).

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).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 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).

Trofisch niveau (Ref. 69278): 2.0 ±0.00 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
