The West African gaboon viper has the longest fangs of any snake. In a 6ft (1.83m) long specimen they measured 2in (50mm). Snakes don’t blink as they have transparent eyelids that are fused shut.

Gaboon vipers live in select parts of Africa, while king cobras live in Southeast Asia and India. King cobras can’t sense heat like pit vipers, but they have better eyesight than most snakes.
