elongated, without scales, almost covered with bony plaque, ventrally
flattened in adults. Terminal mouth has three pairs of barbels.
Lower jaw is shorter than the upper jaw. Eyes small. Feeds on
fruits when the forests are flooded and on the blades of macrophytes

in the estuary of the Amazon, in the region of Mario. |
