The brown bullhead is a catfish with a sharp, venomous spine on its fins. It lives in lakes, ponds and slow streams across North America, and it is important to the Ojibwe people, who see it as one of their clan symbols.1

Jinsi ya kumtambua

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

Mara nyingi huchanganywa 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. The flathead catfish lacks the brown bullhead's tooth patch on the upper jaw.1

Nguvu ya sumu

Miiba yenye sumu

Miiba mikali hubeba sumu. Kumkanyaga au kumshika kunauma.

Sumu yake hufanya nini?

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

Ana hatari gani kwa watu?

Hatari kwa watu: InaumaInaweza kuuma sana, lakini karibu kamwe si jambo zito.

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

Hufanya nini akiogopa?

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

Miiba yake ikikuchoma

Weka jeraha kwenye maji ya moto, moto kiasi ambacho mtu anaweza kuvumilia bila kuungua (pima kwanza kwa mkono wako), kwa dakika 30 hadi 90. Tafuta msaada wa kitabibu, hasa kwa samaki-jiwe na taa.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Miiba yake ikikuchoma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

It can survive very low oxygen levels, down to 0.2 ppm, and even heavily polluted water.1

Its spines can produce venom, which is unusual for a catfish species that is otherwise common and widely eaten.1

The brown bullhead is one of six beings in Ojibwe tradition that came out of the sea to form the original clans.1

Both males and females are known to eat their own eggs at times.1
