Sydney funnel-web spider, Atrax robustus, is usually found within a 100 km radius of Sydney, New South Wales, Australia. The spider can be very aggressive when provoked. They are attracted to water and hence are often found in swimming pools where they have fallen while wandering. These spiders typically deliver a full envenomation when they bite, often striking repeatedly, due to their aggressiveness and large chitinous cheliceral fangs. Chances of being bitten are high if encountered. There is at least one recorded case of a small child dying within 15 minutes of a bite from a Sydney funnel-web spider; that event occurred before the development of an antivenom. Since the antivenom was developed in 1981, there have been no recorded fatalities due to this species. It is also known that because of their large fangs, the victim has to pull the spider from the area of insertion. They will not detach if you shake that area.
