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

A stonecat's pectoral spines carry venom glands, which makes them far more painful than the spines of most related catfish.1

Its eggs are amber-yellow and very large for a fish, measuring between 3.5 and 4 mm across.1

Stonecats are used as indicators of water quality, because they are absent from highly polluted or heavily silted areas.1

Stonecats form monogamous pairs for breeding, and they spawn when water temperatures reach 25 °C.1

The upper jaw of the stonecat projects beyond the lower jaw.1
