Mojave Rattlesnake
Mexico is home to one of the world’s most venomous snakes. According to the World Wildlife Foundation, it is not endangered in any way. The Mojave Rattlesnake, in particular, is extremely aggressive toward humans, and if not treated immediately after a bite, it can kill a person in less than an hour.

King Cobra
The King Cobra, the world’s longest and most venomous snake, can be found in Asia and India’s jungles. It is not a “true cobra” with a length of up to 18.8 feet. What did you just say? It does belong to its subgenus class. Does that make it a little less terrifying? Okay, fine, maybe it will help. King Cobras aren’t usually deadly to humans because they hunt lizards, rodents, and other snakes. On the other hand, this critter has enough neurotoxin in its venom to paralyze and kill an elephant in just a few hours. Oh, and if it bites a person, they only have a 40% chance of surviving.
