When eaten, it has been linked to cases of mild ciguatera-like poisoning. Ciguatera is a form of food poisoning caused by toxins in some reef fish.1

Senzani uma sesabile?

Uma ameva aso ekugwaza

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 ameva aso ekugwaza: 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 spines are mainly a defence against predators. The highest predation pressure falls on its larvae and planktonic stages.1

It came to the Mediterranean through the Suez Canal. It was first recorded off Israel in 1955 and has since spread as far west as the French Mediterranean coast and the Adriatic Sea.1

It is a daytime feeder. At night it hides in cavities in the reef.1

It is an important fish for fisheries in the Mediterranean. In Kenya, it is caught mainly as bycatch.1
