Last year about 65 people were bitten by the funnel-web spider in Australia and their life were saved. Funnel-web spiders are between 1-5 cm in length, have shiny carapaces and can live up to 30 hours under water. The antidote has a shelf life of only 18 months, and can take up to two years to produce. After capture, spiders are milked for venom once a week. The venom is sent to laboratory Bio CSL where it is injected in incremental doses into rabbits. They build up antibodies in their blood, which the laboratory extracts to make a serum. A funnel-web male spider typically lives for only six months.
