Different species of spiders produce different silks that serve different purposes, from floating on air to cradling eggs. The triangle weaver spider, Hyptiotes cavatus, weaves and holds a three-sided web under tension, which it releases the moment prey flies into the web, quickly tangling the prey in the spring-loaded threads. Thus, the web can move much faster than any muscle in the spider's body, illustrating how silk can amplify a spider's abilities.
