Top 10 Most Dangerous Spiders In The World
2. Sydney funnel web
Sydney funnel-web spiders are mostly terrestrial spiders, favouring habitats with moist sand and clays. They typically build silk-lined tubular burrow retreats with collapsed “tunnels” or open “funnel” entrances from which irregular trip-lines radiate over the ground. Funnel-web spider venom contains a compound known as atracotoxin, an ion channel inhibitor, which makes the venom highly toxic for humans and other primates. However, it does not affect the nervous system of other mammals. These spiders typically deliver a full envenomation when they bite, often striking repeatedly, due to their defensiveness and large chitinous cheliceral fangs.
