All You Need to Know About Spiders Spiders are super predators and devour everything they can overpower. To do this, they have developed incredibly good catching techniques and, with spider silk, a tool that makes material technology green with envy. The males are usually smaller than the females and, in order to have sex, they have to come up with a lot to avoid being misunderstood as easy prey: Dancing, drumming, and gifts almost always help. Spiders use their venom in very precise doses, and since humans are not on their menu, they are harmless to us. Many people's (unnecessary) fear of spiders finds cultural roots as early as the Middle Ages. Nevertheless, spider fear is easily treatable. There is no habitat or building without spiders. And that's a good thing, because spiders have fascinating properties and their world is full of surprises.
