Distinguished from its only congener, Amblyrhynchichthys truncatus, in possessing a more truncate snout (straight vs. gently rounded lateral profile), shorter dorsal spine (15.5-25.7% SL vs. 26.7-29.9), smaller eye when similar-sized individuals of larger than ca. 7 cm SL are compared (28.7-34.9% HL vs. 32.7-36.3) and fewer gill rakers (34-37 vs. 39-40) (Ref. 55878).
Body shape (shape guide): fusiform / normal.
Inhabits mainly rivers, with juvenile occasionally entering swamps and flooded fields and feeds mainly on periphyton (Ref. 55878).
