Webs are sticky and designed to catch prey but spiders don’t seem to get caught in their own webs. The reason for this is that the spider knows its own trap and so doesn’t make full contact with the web at any one time. Instead, it uses the hairs on its legs or the very tips of the legs to walk on the non-sticky parts, avoiding getting stuck. What’s more, these eight-legged creatures are meticulous about cleaning and will groom themselves to get rid of any debris that could see them getting trapped.
