Short description
Identification keys | Morphology | Morphometrics
Jaws increasing in length throughout life, extending far beyond posterior margin of eye in large specimens; small juveniles with slightly oblique bars on body and anal fin; larger juveniles and adults with plain body, overall silvery to bronze in life (Ref. 43281).
Obligate air-breathing (Ref. 126274); Inhabits mainstreams and forest streams (Ref. 58784). Feeds on fishes, probably has a crepuscular or nocturnal activity pattern (Ref. 12693). Other food of this species includes insects and small vertebrates (Ref. 58784).
