Do spiders have feet or hooks or pads & why don't they get stuck in webs?

Any pictures or web pages?

Do spiders have feet or hooks or pads %26amp; why don't they get stuck in webs?
Actually, spiders could get stuck in their own webs--they're just more careful than that. You see, some of the strands are sticky, and others are not. The spiders only climb on the NON-sticky strands. Even if they accidentally set foot on a sticky strand, as long as it's not their whole body or multiple legs, they can still pull their foot free fairly easily. It's not THAT sticky.





Web-building has several phases. A spider begins by attaching a single strand of silk horizontally between two supports, such as twigs or branches. It then builds an outside rim -- almost like a bicycle wheel -- and attaches spokes and a spiral from the centre to the outside of the web. These parts of the web are all composed of non-sticky silk. With this frame - the foundation for a decent web - firmly in place, the spider adds the sticky strands, once again in a spiral pattern. This spiral is connected to the non-sticky spokes. "So, when a spider runs across from the centre of the web to grab a prey, it tends to go along a spoke, stepping on the bits that aren't sticky





Also some spiders have oil on their bodies. The oil is slippery, so the web won't stick to it.





Spiders are Sooooo Cool!

She can tell by the vibrations of the thrashing victim what route to take to get there.
