Ubunzima
500 g ukuya ku-3,6 kg (1,1 lb ukuya ku-7,9 lb)1

Indlela yokusiqaphela

  • 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

Sidla ngokubhidaniswa no: 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 etyhefu yokuluma nokuhlaba

Amava anetyhefu

Amava abukhali aphethe ityhefu. Ukusinyathela okanye ukusibamba kubuhlungu.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

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: KubuhlunguKunokuba buhlungu ngokwenene, kodwa phantse akusoze 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

Senza ntoni xa soyika?

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

Ukuba amava aso ayakugwaza

  • 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 amava aso ayakugwaza: 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
