The World’s Most Dangerous Spiders – A Bite‑Sized Guide for the Curious (and Cautious)

Also known as: The “funnel‑web terror” of Australia’s east coast.

• Geographic range: Coastal New South Wales, especially around Sydney.
• Venom profile: Contains atracotoxin, a fast‑acting neurotoxin that can cause severe systemic effects (muscle fasciculations, respiratory failure).
• Bite frequency: Males wander during mating season (late summer), increasing human contact. Females are more sedentary but fiercely defensive.
• Medical notes: Since the introduction of a specific antivenom in 1981, fatalities have dropped dramatically. Prompt medical attention is still essential.

Why it’s dangerous: Historically responsible for the majority of spider‑related deaths in Australia until antivenom became standard.
