Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Distinguished from other members of the family by the presence of a row of large ocellated spots above the base of the anal fin (Ref. 27732). Differs from C. chitala in lacking silver or gold transverse streaks on dorsum and from C. blanci and C. lopis in lacking a basal pectoral spot (Ref. 7431).
Body shape (shape guide): elongated.
Obligate air-breathing (Ref. 126274); Adults inhabit flowing waters of large and medium-sized rivers (Ref. 12693). Within the Mekong mainstream, they occur in pools (Ref. 37770, 36667). They feed on surface-feeding fishes, crustaceans and insects, with a crepuscular or nocturnal activity pattern. They move into inundated forest during the high water period from June to October. Individuals from the Great Lake are shipped to markets in Thailand (Ref. 12693).
