The Xingu River ray is a freshwater stingray that lives only in the Xingu River basin in Brazil. It likes clear water over rocky riverbeds. It has a venomous spine in its tail, so it is one to admire from a distance.1

  • Teeka ekiwundu mu mazzi agookya, agookya nga omuntu bw'asobola okugumiikiriza nga tegamwokya (gagezese n'omukono gwo), okumala eddakiika 30 okutuuka ku 90. Funa obuyambi bw'abasawo, naddala ku stonefish ne stingray.

Bulijjo sooka kuba ennamba y'ebigwa bitalaze (112, 000, 911). Buno bulagirizi bwa bujjanjabi obusooka obwa bulijjo, si kuwabula kwa musawo. Obujjanjabi obusooka obw'omusingi
