Deadliest Animals on The Planet

#1 Blue-Ringed Octopus
The blue-ringed octopus can be found in crevices in tide pools and coral reefs. Despite their small size (5 to 8 inches), their venom is powerful enough to take down a human. Once bitten, numbness and paralysis may begin to take place. Death usually results from respiratory failure.
 
#12 Golden Dart Frog
The poison dart frog may be small, but it packs a deadly poison called batrachotoxins. Coming into contact with one of these guys can kill you almost instantaneously. Each one carries enough poison to kill between 10-20 humans.
