Most Venomous Snakes in the World

About This Dataset

Snakes ranked by the lethality of their venom measured by median lethal dose (LD50) in mice. The inland taipan of Australia is considered the most venomous snake on earth — its venom is so potent that a single bite contains enough toxin to kill 289 humans. Despite this, it is rarely responsible for human deaths due to its remote habitat.

Analysis

King Cobra heads the table on 1.80, ahead of Black Mamba (0.32) and Philippine Cobra (0.20) in LD50 (mg/kg). 1.78 separates the highest figure (1.80) from the lowest (0.03) in LD50 (mg/kg). Most of that gap is between first and second alone (1.48 of 1.78); the other 7 are separated by just 0.30. Only 1 of the 8 reaches even half the leader's figure (0.90 or more).
