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

Sihlala

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

IAsiya

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

5 m (16 ft)1

Ubunzima

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

Esona santya siphezulu

malunga ne-30 km/h (19 mph)

Sitya ntoni?

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

Indlela yokusiqaphela

Plain grayish brown on top, often with a yellowish or pinkish tint towards the fin edges1
White underside with broad dark bands on the rear edges of the pectoral and pelvic fins1
Thin, whip-like tail that is black behind the spine and has no fin folds1
Sharply pointed snout that projects beyond the disc1

Sidla ngokubhidaniswa no: Similar freshwater stingrays in South Asia, Southeast Asia and Australasia were once tentatively grouped with this species. Some of them, such as the Australian Urogymnus dalyensis, are now described as separate species.1

Amandla etyhefu yokuluma nokuhlaba

Ukuhlaba

Ityhefu iphuma ngenaliti yokuhlaba.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

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

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: Kubi kakhuluUkuhlatywa kufuna ugqirha. Ukufa kunqabe 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

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

Iinyaniso

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
