Description synthétique
Clés d'identification | Morphologie | Morphométrie
Rayons mous anaux: 31 - 34. Dorsum dull grey; blunt snout lacking broad white band around muzzle; 24-35 gill rakers in the first arch (Ref. 12693).
Facultative air-breathing (Ref. 126274); Bears strong resemblance to P. bocourti but has different gill-raker counts and coloration. Diet consists mostly of benthic insect larvae and worms, with some free swimming insects, submerged plants and seeds (Ref. 12693). Undertakes upstream and downstream migrations in the Mekong mainstream (Ref. 37770). Length type for maximum size is assumed in TL.
