Fun facts

  • It feeds mainly on fruit and seeds falling from the trees of the flooded forest, and is one of Amazonia's great seed dispersers: up to 89% of the seeds that pass through its gut still germinate.
  • It disperses better than the tambaqui because more seeds pass through it intact.
  • The juveniles mimic the red-bellied piranha, with a red chest and belly; they are told apart by the teeth, which in the pacu are molar-like.
