Hexathelidae is the only family in the superfamily Hexatheloidea, and one of two families (along with Dipluridae) of spiders known as funnel-webs. This order is sometimes incorrectly referred to (in unknown references) as the venomous funnel-web tarantulas, due to the inclusion of the Australian funnel-web spiders, including the Sydney funnel-web spider (Atrax robustus). Most species in Hexathelidae are not dangerous to humans.
