Why the Spider Does not get Caught up in his Web
Unlike unsuspecting prey, spiders don’t come into contact with their webs all at once. Instead, they move nimbly along the strands of their webs with only the hairs on the tips of their legs making contact with the sticky threads. This minimizes the chances that they’ll get caught in their own trap
Why are spider webs so sticky? Spiders who weave webs use them to catch flies and other insects and small animals that they eat for food. For example, when a fly unknowingly flies into a spider web, it quickly becomes trapped. A spider’s silk is sticky, but also very strong. The spider can then subdue it and have a quick meal!
If you’ve ever watched a spider move across its web, though, you may have noticed that it doesn’t get stuck like its prey. Instead, spiders move quickly and efficiently around their webs as if they weren’t sticky at all. How do they do that?
