How do spiders build webs?

Spiders build webs using silk produced from specialised glands called spinnerets. The process begins with the spider releasing a strand of silk into the air until it catches onto a surface, forming the web’s initial anchor. The spider then constructs a framework by connecting more silk lines, creating the radial and spiral structures. The sticky silk in the spiral traps prey, while the non-sticky threads allow the spider to move freely. Web-building techniques vary by species, with orb-weaving spiders creating intricate circular patterns and others, like funnel-web spiders, crafting tunnel-shaped webs. The silk is incredibly strong, lightweight, and versatile.
