The tadpole madtom is a small freshwater fish that lives in slow, weedy waters in Canada and the United States. It has two spines near its chest that carry a venom, which it uses to defend itself from predators. Its name comes partly from its rounded tail fin, which makes it look a little like a tadpole.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

Wat doen dit as dit bang is?

When startled, it darts about in all directions, and it uses its venomous spines against predators.1

As sy stekels jou steek

Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand (toets dit met jou eie hand), vir 30 tot 90 minute. Kry mediese hulp, veral vir klipvisse en pylsterte.

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 sy stekels jou steek: 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
