awesome stories (and that last macro)!
golden orb weavers are usually large when they're about three inches across (including legs). this one looks like three inches in the body alone! they produce an unusually strong, sticky web that has a golden colour in the sunlight, and they don't actively hunt. as far as i know they're not especially dangerous - never been bitten by one and don't plan to be. like most spider species, the female is the monster you see dominating the web, and it's not unusual to see spindly, tiny, fragile little males hanging around elsewhere on a large web.
everyone knows that the sydney funnel web spider is considered the most dangerous in australia. its venom is only dangerous to primates (of all mammals!), and they like to occupy untidy heaps of clothes on the floor (usually in the northern suburbs, lucky for me). little known, though, is the fact that the funnel web endemic to my home area in the northern rivers region of NSW is even more toxic and venomous than the sydney funnel web. it's considered less dangerous because of the lower population density there. i never knew that until recently.
not that you'd let one of them get anywhere near you - they're aggressive, ugly, dangerous looking spiders. once caught in a plastic take away container we put any spiders we don't want to return to the garden into the freezer for an easy death.
here are some shots of such. the first two were frozen first, but the third one was (at that stage) alive and well on our back patio.
