Blue Ringed Octopus
About the size of a golf ball, don’t let its small stature fool you, it holds enough venom to kill 26 full grown adults and as you may have guessed, there is no antidote. Assuming that your friend ever gets bitten you had better know CPR because you can be sure that within minutes they will be completely paralyzed and unable to breathe. Mother nature, however, shows no mercy and they will maintain their consciousness for the next few hours until the venom is neutralized by their body. This is of course assuming that you, or someone at the hospital, continues artificial respiration.
Although they are mostly herbivorous, they are also highly aggressive and are widely regarded as one of the most dangerous animals in Africa. They have been known to attack humans without provocation even to the point of destroying entire vehicles.
Sitting at the top of its food chain the Saltwater Crocodile has been known to eat everything from water buffalo to sharks. In order to kill its food it make use of a technique called the “death roll” where it relentlessly flips its prey over and over in the water until it drowns and then comes apart.
The world’s largest land animal, elephants can be fiercely aggressive and have been known to trample even a rhinoceros or two to death. They seemingly have the capacity to display bouts of rage and have even engaged in activities that have been interpreted as vindictive, razing entire villages in the process.
Moving from one of the largest animals in the world we now come to one of the smallest. As small as it is though, it is also the deadliest. It has been estimated that mosquitos transmit diseases to almost 700 million people annually resulting in 2 to 3 million deaths every year.
