Native habitat: Eastern Australia
Death toll: 1, but no recent deaths have occured due to the development of antivenom
Why you should be terrified of them: Its venom is very poisonous, but only when it comes from the male species. If stung, the venom will begin to take over the nervous system

Funnel-web spiders are usually watching for prey in the foresty areas of Australia. Not all species are poisonous, but those that are extremely poisonous. The venom of the male contains Robustoxin, which is a toxin that completely destroys the nervous system of humans, monkeys, and other mammals. Thanks to scientists, an antivenom was discovered in 1981 and since then no deaths have been recorded.
