Kuogelea, makadirio

Hula nini?

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

Jinsi ya kumtambua

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

Mara nyingi huchanganywa na: 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

Nguvu ya sumu

Kudungwa

Sumu hutoka kupitia mdungo.

Sumu yake hufanya nini?

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

Ana hatari gani kwa watu?

Akidunga

Weka jeraha kwenye maji ya moto, moto kiasi ambacho mtu anaweza kuvumilia bila kuungua (pima kwanza kwa mkono wako), kwa dakika 30 hadi 90. Tafuta msaada wa kitabibu, hasa kwa samaki-jiwe na taa.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

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
