Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 76 - 87; Rayons mous anaux: 63 - 69; Vertèbres: 60 - 64. Head rectangular to oval-shaped dorsally; snout broadly rounded; eyes laterally placed. Frontal fontanelle long and narrow; occipital fontanelle small and oval-shaped. Supraorbital and `dermosphenotic' bones separate but not reduced. Tooth plates broad. Pectoral spine slightly curved; outer side with strong, downward serrations. Gill rakers short and squat, although distantly set. Suprabranchial organ rather primitive. Openings of the secondary sensory canals display a regular pattern.
Body shape (shape guide): elongated; Cross section: circular.
Facultative air-breathing (Ref. 126274)
