Saw-scaled viper The saw-scaled viper isn’t the most venomous of snakes – that accolade goes to the Inland or Western Taipan, native to central Australia – but it is among the most aggressive and is the deadliest to humans. Found in India, Pakistan, Sri Lanka, and parts of Africa and the Middle East, it often lives near inhabited areas and strikes often, with terrifying speed. It’s estimated that a staggering 5,000 people are killed by them each year – the highest death toll of any snake.
