Anatomy of the pharyngeal apparatus is the main distinguishing characteristic; throat teeth typically form a single row of 4-5 large molariform teeth on each of the two arches, with formula typically 1,4 - 4,1.

Habitat and Ecology:
Habitat and Ecology
In its natural distribution range, Mylopharyngodon piceus inhabits large lowland river and lakes, preferably with clear water and high oxygen concentration (Kottelat and Freyhof 2007). Spawns for the first time at 6-11 years, females later than males (at about 1000 mm SL and 15 kg, males at 900 mm and 11 kg, fecundity is about 700-800 thousand eggs). Migrates upriver and spawns in open water during flood phase. Eggs are pelagic or semipelagic and hatch while drifting downstream. If the river flow is blocked or if available river stretches are too short, eggs cannot drift for long enough and fail to develop. Larvae migrate into floodplain lakes and channels with little or no current. Larvae feed on zooplankton, then on ostracods and aquatic insects. At about 120 mm SL, juveniles start to feed on small snails and clams. Larger juveniles and adults feed almost entirely on molluscs (source: Kottelat and Freyhof 2007).
