From Nepal and Srilanka to Taiwan and Australia lives the 1 centimeter Portia Spider. Portia Spiders can jump as far as 50 times their size. These intelligent spiders plan their attacks. They pretend to be prey to lure their prey, other spiders! They do this by shaking a spider’s web imitating other spiders. And when the spider comes to investigate. WHAM it jumps on their back. It is over quickly. I find this spider horrifying and do not want one for Christmas.
