6 Most Terrifying Creatures On Earth That Might Actually Kill You

Sydney Funnel-Web Spider – The 15-Minute Killer

This Australian spider is considered the world’s deadliest spider. Its venom is strong enough to kill a human in under an hour – potentially in as little as 15 minutes. Aggressive when threatened, it bites multiple times and delivers a neurotoxin that attacks the nervous system. The Sydney funnel-web is aggressive, fast, and doesn’t hesitate to strike. If you see one, don’t walk – run.
