I was in Manaus/Amazon during the Brazilian Aquathlon (swimming and running) championship in . This river is called Rio Negro (Black River) due to water color. Rio Negro is the largest left tributary of the Amazon, the largest blackwater river in the world. While the name Rio Negro means Black River, its waters aren't exactly black; they are similar in color to strong tea. The dark color comes from humic acid from incomplete breakdown of phenol. I photographed it from the water and my lens got completely wet, but there was so energy in this boys that I just didn't worry about that.
