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

Ñu ngi koy faral di jaxasoo ak: 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

Xibaar

Its venom toxicity drops as it gets older, while the venom's makeup stays the same.1

It can weigh up to 20 kg, which is very large for a freshwater stingray.1

As it matures, its jaws become stronger, which lets it eat hard-shelled invertebrates.1

Females grow larger than males.1
