Scientists have identified a new species of freshwater stingray, named Potamotrygon siponinmorok, discovered in the rivers of Guyana and Venezuela. This species is distinguished from its relatives by subtle morphological differences, including a longer tail, a different number and shape of teeth, and a unique lateral line system. Genetic analysis further confirms its distinct evolutionary lineage, highlighting a broader pattern of hidden diversity within South American freshwater fish. AI
