1. Box Jellyfish
The box jellyfish have a lot of sub-species and each of them is considered very deadly. The floating translucent fishes may not seem much of a threat, but they have one of the most venomous and painful stings known to man. Most who have encountered a box jellyfish have not lived to tell the tale of its sting.
Whether it is an animal by air, land or sea, it would be better off not provoking an animal that may have a weapon that can be lethal to your life. Always be aware wherever you go and be sure to research a place and especially the animals if you plan to go into the wilderness. That is our list of the 11 most dangerous animals in the world.
