  • 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

Ikunze kwitiranywa na: 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.

Amahwa afite ubumara

Amahwa atyaye ni yo atwara ubumara. Kuyikandagira cyangwa kuyifata birababaza.

Ubumara bwayo bukora iki?

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

Iteje akaga kangana iki ku bantu?

Akaga ku bantu: IrababazaIshobora kubabaza cyane, ariko hafi ya buri gihe nta kibazo gikomeye biteza.

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

Ikora iki iyo ifite ubwoba?

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

Niba amahwa yayo akujombye

  • Shyira igikomere mu mazi ashyushye, ashyushye uko umuntu abyihanganira atiriwe ashya (bigerageze ukoresheje ukuboko kwawe), mu gihe cy'iminota 30 kugeza kuri 90. Shaka ubufasha bwa muganga, cyane cyane ku bya stonefish na stingray.

Buri gihe banza uhamagare nimero y'ubutabazi (112, 000, 911). Izi ni inama rusange z'ubutabazi bw'ibanze, si inama za muganga. Ibanze by'ubutabazi bw'ibanze

Irinde akaga

  • Ntuzigere ukora, ufata cyangwa ushotora inyamaswa yo mu gasozi, nubwo yaba ntoya, kandi nubwo yasa n'isinziriye cyangwa yapfuye.
  • Yihe umwanya. Niba uhuye n'imwe, tuza, usubire inyuma buhoro buhoro kandi uyireke yigendere.
  • Niba amahwa yayo akujombye: tuza, ntunyeganyege, hamagara nimero y'ubutabazi (112, 000, 911) cyangwa ujye ku bitaro vuba. Ibuka uko yasaga, ifoto irafasha.

Ntigushakisha ngo ikugirire nabi. Ikoresha ubumara bwayo kugira ngo ifate ibyo kurya cyangwa yirinde, kandi ikunda cyane kwihisha. Ibindi ku kwirinda
