Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Its bite is painful. The venom contains neurotoxins, which attack the nerves. Several neurotoxins that are specific to crustaceans and insects have been found in it. The bite is fatal in rare cases.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Ernstig'n Byt moet deur 'n dokter gesien word. Sterftes is baie skaars.

Its bite is painful and can be fatal in rare cases. Epidemics of bites have been reported, and Ukrainian farm workers have been bitten in the fields. In Kazakhstan, where it is called karakurt, it has been reported to bite and kill camels. Only the female's bite is dangerous to people and cattle, because the male cannot get through the thick outer skin.1

As dit byt

Was die byt en sit 'n yspak daarop vir die pyn. Kry mediese hulp as die pyn erg is, versprei of die persoon sleg voel.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly
