I saw it on the internet. A tumbling spider. It lives in the Middle East. It has these long legs that just flop over and over. I thought it was just having fun, but I realized that tumbling is part of its strategy. When most people see a creepy crawling spider, they want to squash it or run away. If you see a spider somersaulting toward you, you think, oh how interesting. Then it flops on you and you are done. Taken in by a little spider.
Have a nice day.
