According to the World Health organization, between 81,000 to 138,000 people die each year due to snakebites, and three times that number have to have something amputated after being attacked by a snake.
The saw-scaled viper is the undisputed king of death-bringing snakes; it’s responsible for more human deaths than all other kinds of snakes combined. Found across Africa, Arabia, southwestern Asia, India, and Sri Lanka, the saw-scaled viper doesn’t have the deadliest venom—it’s only fatal about 10 percent of the time— but it make up for it in terms of sheer aggression and large numbers. They’re common, and they will attack you just for looking at them.
The Australian Inland taipan is by far the deadliest of all snakes in terms of venom potency. Its brew of neurotoxins, hemotoxins, and myotoxins is so deadly to humans that one bite from Inland taipan possesses enough venom to kill at least 100 people. Luckily, the inland taipan is rare, reclusive, and prefers to avoid confrontation. Almost all of the few reports of bites from Taipan are among herpetologists handling captive snakes, and a rapid course of anti-venom saved most of their lives.
