As a Canadian living in Australia, I prefer the North American dangers. At least you can see most of them. I've nearly stepped too close to a tiger snake once and didn't notice until I put my foot down. Luckily it preferred the warm spot over me.
I usually don't go far in to the water out of fear of dark waters and rips. Seen the cute little blue dragons and jellyfish on beaches, but I leave those alone.
White tailed spiders under the covers, or in your closet or drawers are a joy, especially the baby ones.
If you can stay afloat for a good while you'll be right. They circle back to where waves are forming and the waves carry you back to shore. The key is not to panic and don't exhaust yourself fighting them. Swim sideways and relax, you'll get dragged out some but the waves will help you get back so it's going to be ok once you're out of it.
White tails are harmless, the victim of a libel campaign.
Fair fair. You'll want to avoid bulldog ants if you've got allergies. I know the natural inclination is to get close because they're so fascinating but they're particularly known for provoking anaphylaxis :(
Oh boy. Yes, I have come across those on some hikes. It's unnerving how they look up at you as if they are sizing you up, and walk backwards while still looking at you. Didn't know about the anaphylaxis, only know that the bites are very painful. Thank you!
I wasn't joking about wanting to approach them, they're fascinating. I object to people saying something is less evolved than something else as everything has been evolving and surviving the same amount of time, but they are primitive in the sense of preserving characteristics from an intermediate stage between wasps and ants. Really fascinating to see the solitary roaming/eyesight heavy foraging behaviours alongside eusocial grooming etc.
Gosh I love them, but I don't know how many stings I have left in me as it's starting to get extremely painful :p. They are just about the only animal aside from domestic cats that seem to go out of their way to do violence to you with very little provocation.
