DANGEROUS SPIDERS IN AUSTRALIA
Dangerous Spiders: There are nine Australian Spiders whose venom ranges from extremely toxic to resulting in painful bites. Common sense and awareness will safeguard most people from the danger of attack. These spiders are as listed below:
SYDNEY FUNNELWEB-(MALE) The most dangerous spider in the world is the male Sydney Funnel Web. It has killed three children in under two hours. This spider is quickly identified by a glossy black body with long spinnerets. An aggressive spider which rears up when challenged. His venom is seven times as toxic as the female, yet is dangerous only to primates. Secondary identification is a pointed spur on each second leg and reddish black undersides.
SYDNEY FUNNELWEB-(FEMALE) Similar in appearance with a stockier body than the male. Lives in web-lined retreats in moist, cool locations. The female although less toxic than the male, has caused fatalities, mainly amongst the young, old and sick population.

Around 300 spider bites are recorded every year from the Red-Back with seven fatalities attributed.

Usually encountered inside houses sheltering from the weather or introduced on clothing brought in from the clothes line. Bite is not usually painful, though may become very painful at a later stage. Ulcers may develop to a stage where necrosis of the skin occurs.
BLACK HOUSE SPIDER Both sexes are dark brown to grey/black with b
ody markings. Builds webs in dark corners of windows, verandahs, sheds or fences. Bite very painful with severe vomiting and nausea resulting. No fatalities recorded.
