Description synthétique
Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 10 - 14; Rayons mous anaux: 3 - 5.
Body shape (shape guide): elongated; Cross section: flattened.
Facultative air-breathing (Ref. 126274); Typically from floodplain lakes, swamps and borrow pits, in poorly-oxygenated waters and must rely on air breathing for long periods of time. Has a specialized (enlarged) stomach which appear to function as accessory respiratory organs (Ref. 58517).
