I think you're right. Wasn't that the "Face-Ripper" episode where they discovered that black piranhas were now schooling or shoaling because of dam flooding? At first he thought pimas or some other large species was behind the death of some migrant fisherman.

There's been no formal division of Arapaima gigas. There is a proposal to divide the genus into three species including A. gigas. The proposals include the tentative names of A. arapaima for the population in Guyana and A. mapae for the population in northeastern Brazil.
The rediscovery of A. agassizii since it's original discovery date in 1847 is a fourth proposed species of the genus.

Arapaima crossed with a bichir? Truly an amazing animal, I would love to see a live one.
Aren't they an over 100 million years old genus. I will not be surprised if the different localities has resulted in speciation.
Would love to know that the purported 5 species are still existant.
On another note, Pirarucu is Yanomani, not Portuguese, and Paiche is a native modification of "Peixe ", which is fish in Portuguese.

I was thinking along this same line. I wonder if these variations are just the result of locality/breeding with in isolated populations rather than distinct species. Kind of like humans. We are all the same species, but when you look at biological markers, you can tell where the persons genetic line originated.
