The toadlike bolas spider is a spider from the United States that hunts in a very clever way. The grown-up female does not build a web at all. She swings a single silk thread with a sticky drop at the end, like a fishing line, and catches insects with it.

Fun fact: spiders are not insects. Insects have six legs, spiders have eight. Everyone calls them bugs anyway!
