Funnel-web spiders are a group of spiders known for their unique web structures, which resemble a funnel. These webs are typically built in sheltered areas, like under rocks or in leaf litter, where the spider waits for prey to wander in. When an unsuspecting insect falls into the web, the spider quickly pounces to catch its meal. There are many species of funnel-web spiders, but some, like the Sydney funnel-web spider, are particularly famous for their potent venom. While their bites can be dangerous to humans, these spiders play an important role in controlling insect populations in their ecosystems.
