Blue Ringed Octopus
About the size of a golf ball, don’t let its small stature fool you, this dangerous animal 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.

Sitting at the top of its food chain the Saltwater Crocodile has been known to eat everything from water buffalo to sharks.

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 mosquitoes transmit diseases to almost 700 million people annually resulting in 2 to 3 million deaths every year.
