The Xingu Freshwater Stingray (Potamotrygon leopoldi), also known as the Black Diamond Stingray, is a strikingly patterned freshwater ray endemic to the fast-flowing waters of the Xingu River in Brazil. Distinguished by its black body adorned with bright white or yellow spots, this ray can reach up to 45 cm in diameter and weigh between 10 and 15 kg. It feeds on small invertebrates and fish found in the rocky, shallow riverbeds of the Amazon basin. With an estimated population of 2,000–3,000 individuals, the Xingu Freshwater Stingray faces critical threats from over-collection for the aquarium trade, habitat disruption due to dam construction, and pollution. Additionally, climate change impacts, such as altered water flow and temperature, pose long-term risks to its habitat. Conservation measures focusing on regulating trade and protecting the Xingu River ecosystem are essential to safeguard this vulnerable species.
