Indlela yokusibona

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

Ivamise ukudidaniswa ne: 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 obuthi

Ukuhlaba

Ubuthi buphuma ngodosi.

Ubuthi baso benzani?

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?

Ingozi ebantwini: Kubi kakhuluUkuhlatshwa kudinga udokotela. Ukufa kuyivelakancane kakhulu.

Uma sihlaba

Faka inxeba emanzini ashisayo, ashisa ngendlela umuntu angakwazi ukuyibekezelela ngaphandle kokusha (yihlole ngesandla sakho), imizuzu engama-30 kuya kwengama-90. Thola usizo lwezokwelapha, ikakhulukazi kuma-stonefish nama-stingray.

Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala

Hlala uphephile

Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
Uma sikuhlaba: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.

Asikuzingeli wena. Sisebenzisa ubuthi baso ukuze sibambe ukudla noma ukuzivikela, futhi singancamela ukucasha. Okwengeziwe mayelana nokuhlala uphephile

Amaqiniso

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
