Spider webs are intricate structures made by spiders using silk produced from specialized glands. These webs serve various purposes, including trapping prey, providing shelter, and creating a safe space for laying eggs. The silk is strong and flexible, allowing the web to absorb the energy of captured insects without breaking. There are different types of spider webs, such as orb webs, funnel webs, and sheet webs, each designed for specific hunting strategies. Spiders can produce different types of silk, which vary in strength and stickiness, depending on the web's function.
