There are two kinds of snake that are tied for the most poisonous snake in the world. The first is the black mamba. The black mamba is found mostly in sub-Saharan Africa, and it is actually the largest species of snake found in Africa that is venomous. They’re often longer than six feet when they are adults, and are able to kill a grown man with their venom in a matter of hours.
Bites are not common, though. The second kind of snake is a taipan.These are found often in Australia, New Zealand, and areas around there. These are considered to be the ones that kill the most people out of the two snakes since they are more likely to bite. Their venom is a neurotoxin.
