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

Sitya ntoni?

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

Indlela yokusiqaphela

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

Sidla ngokubhidaniswa no: 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

Amandla etyhefu yokuluma nokuhlaba

Ukuhlaba

Ityhefu iphuma ngenaliti yokuhlaba.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

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

Siyingozi kangakanani ebantwini?

Ukuba siyahlaba

Faka inxeba emanzini ashushu, ashushu kangangoko umntu angakwazi ukunyamezela ngaphandle kokutshiswa (wavavanye ngesandla sakho), imizuzu engama-30 ukuya kwengama-90. Fumana uncedo lwezonyango, ingakumbi kwii-stonefish nakwii-stingray.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
Ukuba siyakuhlaba: hlala uzolile, musa ukushukuma, tsalela inombolo kaxakeka (112, 000, 911) okanye uye esibhedlele ngokukhawuleza. Khumbula ukuba sasikhangeleka njani, ifoto iyanceda.

Asikuzingeli. Sisebenzisa ityhefu yaso ukubamba ukutya okanye ukuzikhusela, kwaye singakhetha ukuzimela. Okungakumbi malunga nokuhlala ukhuselekile

kufanelekile ukwazi

Iinyaniso

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
