Katipo Spider
Due to it being endangered, you probably won’t come across this New Zealand dwelling spider. The katipo is actually another member of the widow spider family. Just like other widow spiders, the bites are not only painful but at times fatal. FYI, only females can bite since the fangs of a male are too small to puncture someone. So, try to avoid females? Yeah, sorry that’s the best preventative advice we got for you!
Southern Tree Funnel-Web Spider
Along with its relatives that we covered, this Australian spider is one of the most dangerous of its species. If you didn’t already guess, they live in the trees. Around half of the bites they inflict result in severe envenoming. Probably, not the kind of odds I would bet on.
