How do spider webs move

A spider relies on the wind to carry the filaments across wide intervals. … Spiders that build the familiar orb-shaped web usually start with a single superstrength strand called a bridge thread or bridge line. The telescoping protein structure of this silk is believed to gives it its strength.

Making webs is instinctive for spiders, which means nobody has to teach them how to do it. They are born knowing how. When a spider begins a web, it releases a silk thread. It anchors the thread to some object — a branch, a corner of a room, a doorframe — wherever it builds its web.

Spiders walk by alternating two pairs of legs. While two pairs of legs are in the air, other two stay on the ground and support the body. The amazing part of spider walking is that spiders are able to walk on both horizontal and vertical surfaces.
