The very same day that I was imagining spiderweb anchor lines, I drove by the biggest spiderweb I've ever seen...
...complete with the biggest spider I've ever seen:
- They build the biggest web of any spider, measuring up to 1m in diameter.
- The tensile strength of the web is almost equivalent to kevlar, the strongest man-made material in the world.
- They build their web for life, so it has to last 2-3 years (other spiders tear down and rebuild their webs many times).
- Their webs are big and strong enough to trap small birds, who can tear the web in the struggle to become free. Consequently, the golden orb spider leaves a string of insect carcasses (see the photo above) to alert birds to the web's presence. It's the equivalent to putting a sticker on a sliding glass door to prevent people from walking into the glass (just think... spiders did it first!).
- The largest golden orb spider ever found was discovered in... Pretoria!
