Predation classification of spiders
1. web spider: the most important feature of web spider is web-forming behavior. Spiders secrete mucus through the protrusions at the top of their silk sacs, which can condense into very thin silk when exposed to air. The web made of silk is very sticky, which is the main predation means of spiders. For insects that stick to the web, spiders will first inject their prey with a special liquid jujube digestive enzyme. This digestive enzyme can make insects coma, twitch and even die, and liquefy their bodies. After liquefaction, spiders feed by sucking.
2. Wandering spiders: Wandering spiders don't make webs, but wander around or disguise themselves on the spot to prey on prey, such as tall spiders.
