Black Mamba Venom Can Kill a Human in as Little as 7 Hours
Without antivenom treatment, a black mamba bite has a near-100% fatality rate. Its venom is a powerful cocktail of neurotoxins and cardiotoxins that causes paralysis, respiratory failure, and cardiac arrest. Symptoms begin within 10 minutes; death can occur in 7 to 15 hours without treatment. It delivers up to 400mg of venom per bite — far more than needed to kill a human.
