Actually, I'm more fascinated than frightened by Australia's insect life. I would love to spend a couple hours observing bulldog ants, though they may leap onto me and proceed to sting the crap out of me. Arachnids are the most interesting to watch. I'd be crazy enough to keep a SFW as a pet. I've kept Western Black Widows, Arizona Bark Scorpions, as well as a couple of other species of less-poisonous arachnids (moved on to ant colonies for the moment.) I could sit there for hours and watch my spiders go about their business... makes for convenient moth/cricket/pest disposal too.
But, to further along the 'nightmare critter' aspect of this thread, allow me to introduce the Belostomatidae family.

It doesn't look too scary, but looks can be deceiving. My friend used to keep one in a fish tank. He eventually released it because it was too expensive to keep (the damn thing went through fish like candy.) By far, watching it eat is the most gruesome thing I've ever witnessed (picture a toad being fiercely arrested by powerful claws, then having its insides liquefied and gradually sucked out, an empty bag of skin and bones remaining.) Supposedly it has one of the most painful bites of any insect, but I don't want to be the one to find out. At least it's not lethal to humans...
