W: Hey, Sam! You should take a look at this article about Canadian scorpions.
M: I didn’t know there were scorpions in Canada. I thought they only lived in deserts.
W: Well, the deadly kinds do. Like in Arizona and New Mexico.
M: I thought all scorpions were dangerous.
W: No, only about 25 kinds are deadly to humans. Actually there are over 1,500 different species. But only one lives in Canada.
M: Where in Canada? Not around here?
W: Well, mostly Saskatchewan and Alberta. But yeah, right here in British Columbia too.
M: Is the Canadian kind poisonous?
W: Not for humans. Supposedly their sting is no worse than a bee’s. Anyway scorpions are all over the place. They can live in just about any climate. In fact the only continent where they don’t live is Antarctica.
M: Why? Is it too cold there?
W: There must be other reasons.
M: Do tell me. My curiosity is aroused.
W: OK. According to this article, scorpions can withstand conditions that’d probably kill most other animals. Scientists did all these experiments, like the scorpion was frozen in a block of ice for 3 weeks and when they melted the ice, it just walked away.
M: It was still alive?
W: Yeah. But what’s most amazing is that they also survived radiation levels 200 times higher than would kill a human. No wonder they’ve outlived the dinosaurs.
M: Listen. I’ve got to run. But I’d really like a copy of that article.
W: No problem. I’ll make one for you.
M: Thank you.
