Common Death Adder
The Common Death Adder, one of the most venomous snakes in the world, is located in Australia, New Guinea, and a few nearby islands. Bites left untreated can cause death within 24 to 48 hours. Fortunately, there is an antivenom. In addition, we need to mention that it’s the world’s fastest striking snake.
Green Mambas
First of all, the world actually has three kinds of green mambas, because one is just not enough. Green mambas are all incredibly venomous, highly aggressive, and unpredictable in disposition — Western, Eastern, and Jameson. How terrific is that? Highly arboreal, lightning-quick, and agile are also all three species. In addition, their venom is quick-acting, and the central nervous system is much more devastating with the dendrotoxins, which causes severe neurotoxicity.
