That's a good question! I actually call it Peruvanish, because the Tapajos are not native to Peru. All the others are native species found in Peru but not necessarily found in the same rivers . The only species of Geo that I can find is native to Peru is the Proximus, and I think it looks very similar to Tapajos. Thanks for stopping in and taking a look!
