Sydney Funnel Web (Atrax robustus)
Not only is this shiny beast of burden Australia’s most deadly spider, it also ranked number 1 in the world. It is a relatively large species of spider known to grow to 10cm with rear-facing fangs sharp enough to pierce fingernails. I think it goes without saying that a bite from one of these is fatal unless treated rapidly. Death can occur within 15 minutes of a funnel web bite.
