Which precise geographical feature contains the most concentrated populations of the Zebra Pleco?
Answer
Volta Grande do Xingu
While the overall native range is the Xingu River system, research has narrowed down the highest concentration of wild populations to a specific section known as the Volta Grande do Xingu, which translates to the Great Bend of the Xingu. This localized area represents the critical core habitat for the entire species. The stringent habitat requirements, such as the combination of high flow and rocky substrate, restrict the fish to this turbulent segment, making the ecological health of this specific bend disproportionately important to the species' survival.
