This tributarie has a bedrock associated with areas of high or low altitude, causing the rapids and large waterfalls, resulting in a variety of unique microenvironments for the target species of ornamental fish. It is known that freshwater fish have important biological adaptations developed by long evolutionary process, which allows them to synchronize biological and ecological traits, with the water level fluctuations. The construction of the third largest dam in the world on the Xingu River, was started in 2012, with operation beginning in 2015, and among the many impacts there is the modification of the river system, from the complete filling of the reservoir, leaving a stretch of the river as a lentic system, and downstream of the main dam a section with reduced flow.
