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

Mature rays have jaws that become stiffer and more strongly mineralised with age, so they can eat hard-shelled invertebrates.1

  • Deeper black above than its relative P. henlei1
  • Fewer and larger yellowish-white spots on the upper side than P. albimaculata1
  • Underparts are mostly brownish-dusky1
  • Females grow larger than males1

Wɔtaa fa no sɛ: It is closely related to P. henlei from the Tocantins River basin and P. albimaculata from the Tapajós River basin, and they look similar. P. henlei has a large white centre on its underparts, while this species has mostly brownish-dusky underparts. P. albimaculata has more spots above, and they are smaller than the spots on this species.1

The venom is held in a dentine spine on the tail. Its composition stays the same as the ray matures, but its toxicity decreases as the ray gets older.1
