The giant freshwater stingray is a large ray that lives in big rivers and estuaries in Southeast Asia and Borneo. It is the widest freshwater fish in the world, and it is now endangered because of fishing and habitat loss. It has a long, whip-like tail with a sharp spine near the base.1

Ihlala

Large rivers and estuaries of Indochina (such as the Mekong and Chao Phraya) and Borneo1

I-Asia

Ekhaya

It lives on the sandy or muddy bottom of large rivers and their estuaries. It is sometimes found near heavily populated urban areas, and individuals are often seen at the edge of the river.1

Ubude

Isisindo

300 kg kuya ku-600 kg (661 lb kuya ku-1323 lb)1

Ijubane eliphezulu

Sidlani?

It eats small fishes and invertebrates such as crustaceans and molluscs that live on the bottom. It finds them using electroreceptors, which sense the weak electrical signals of living animals.1

Amandla obuthi

Ukuhlaba

Ubuthi buphuma ngodosi.

Ubuthi baso benzani?

Its sting is sheathed in toxic mucus. The sting is capable of piercing bone.1

Siyingozi kangakanani ebantwini?

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

The giant freshwater stingray is not aggressive. Its sting is strong enough to pierce bone and is coated in toxic mucus, so it should be treated with care.1

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

In June 2022, a specimen caught in the Mekong River was reported as the largest strict freshwater fish ever documented, at about 300 kg.1

It is the widest freshwater fish in the world, growing up to 2.2 m across.1

Its tail spine is up to 38 cm long, the largest of any stingray species.1

Pups are nourished in the womb by a milk-like substance called histotroph, or 'uterine milk', made by the mother.1

In Cambodia, the average weight of a landed ray fell from 23.2 kg in 1980 to 6.9 kg in 2006.1
