The Australian Funnel-Web Spider is a highly venomous spider native to eastern Australia. It is known for its distinctive funnel-shaped web, which it constructs in sheltered locations like crevices and under rocks. These spiders are typically dark in color and can grow up to 5 centimeters in body length. Funnel-Web Spiders are primarily active at night and are known for their aggressive behavior when threatened. Their venom contains a potent neurotoxin that can be dangerous to humans, but antivenom is available. They play an important role in controlling insect populations in their natural habitat.
