Indlela yokusibona

  • Dark brown-green back that becomes lighter green and yellow towards the belly, which is off-white or cream1
  • Dark brown-black speckles over the whole body1
  • No scales1
  • Eight barbels (whisker-like feelers) around the mouth, with black to yellowish brown barbels on the chin1
  • Adults usually measure 20 to 50 cm and weigh 0.5 to 3.6 kg1

Ivamise ukudidaniswa ne: The black bullhead and yellow bullhead are similar. The brown bullhead has yellow-black chin barbels, no pale bar at the base of the tail (which the black bullhead has), and 21 to 24 rays in its anal fin. The flathead catfish lacks the brown bullhead's tooth patch on the upper jaw.1

Amandla obuthi

Ameva anobuthi

Ameva abukhali aphethe ubuthi. Ukusinyathela noma ukusibamba kubuhlungu.

Ubuthi baso benzani?

When attacked, the bullhead stiffens the sharp spine on the front edge of its dorsal and pectoral fins. While doing this, it releases venom that stings and burns the predator.1

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KubuhlunguKungaba buhlungu ngempela, kodwa cishe akukaze kube kubi kakhulu.

Its fin spines can sting and burn, which is its main defence against predators. Treat any caught fish with care and avoid handling its spines.1

Senzani uma sesabile?

When attacked, it stiffens its fin spines to make it harder for a predator to swallow it, and releases venom to sting and burn.1

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
