🐍 Identify and Assess Snakes

23 snakes from around the world: venom type, untreated lethality, onset of symptoms, and the key feature to distinguish them from a similar harmless species.

★ Russell's viper and the saw-scaled viper each kill several thousand people a year in Asia—far more than the black mamba or taipan, despite their fame.
★ The inland taipan's venom is the most toxic per dose in the world, but it lives so far from human settlements that no human deaths have ever been recorded.
★ Garter and grass snakes have round pupils, while European vipers have vertical pupils: this single feature reliably separates the two families in Europe.
★ The black mamba gets its name from the black interior of its mouth, not its skin color—a classic identification trap.
★ The Mojave rattlesnake is the only North American snake with both neurotoxic AND hemotoxic venom, making it disproportionately dangerous for its size.
