Determinatiesleutels | Morfologie | Morfometrie
Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 69 - 80; Anale zachte stralen: 59 - 64. Head oval-shaped dorsally; snout broadly rounded; eyes laterally placed. Frontal fontanelle is long and narrow; occipital fontanelle small and oval-shaped. Supraorbital and `dermosphenotic' bones partially reduced (especially the latter) and distantly set. Pectoral spine short and straight; outer side with strong downward serrations. gill rakers short and distantly set. Suprabranchial organ greatly reduced. Openings of the secondary sensory canals display a regular pattern.
Facultative air-breathing (Ref. 126274)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00357 - 0.01766), b=2.96 (2.78 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Weerstandsvermogen (Ref.
