Description:

Funnel web spiders (genera Atrax or Hadronyche) are toxic spiders in Australia, with the male spider having a venom that is more toxic than that of the female. While many patients will either experience no symptoms or only local symptoms related to the bite, some patients will have a more severe reaction that can be fatal. Patients with more severe disease should receive antivenom in order to prevent serious sequelae.
