I have on CBS news and they're showng exotic animals and they've got a HUGE spider (think, size of hamster), the Goliath spider from South America, which is pretty harmless (it's those teensy spiders that kill you). It actually 'laid' some eggs on camera, which got the guy who brought the animals (spider, gator, etc. etc.) rather excited, but wow, this spider was cool, and boy can it move fast! And it eats birds and mice.
