It is part of the larger Pantanal ecosystem, the world's largest tropical wetland area, which contributes to its rich biodiversity and nutrient-dense waters. The river's course features a mix of deep channels, extensive floodplains, and submerged structures that create ideal habitats for a wide variety of large, powerful fish species. Anglers from around the world are drawn here for the chance to target some of the most iconic and hard-fighting freshwater gamefish found in South America.
