Not all spiders build classic orb webs. There are hunters like the wolf spider that don’t build any webs at all and others that create very functional—if less picturesque—webs, like the funnel-weaving spiders. They generally build webs with a flat surface for capturing prey and a tube that leads down to their own comfy burrow. The spider rushes out when it senses that an insect has gotten tangled in its silk and drags it down to its lair to eat.
