According to thefw, the five deadliest cute animals are the puffer fish, slow loris, blue-ringed octopus, poison dart frog and duck-billed platypus. Each of these animals can appear as cute and cuddly, but can kill humans with just a small amount of their venom. The puffer fish are the second most poisonous vertebrate on the planet. There is no antidote to the venom secreted by a puffer fish, which kills humans by paralyzing their diaphragm.
The slow loris has become an Internet sensation due to its extremely cozy wide eyes and innocent expression. However, when threatened, the slow loris secretes a toxin from its elbows, killing humans by anaphylactic shock.
Blue-ringed octopuses are widely regarded as one of the world's most dangerous animals. The tiny creature is found in tidal regions from Australia to Japan and is frequently encountered in tide pools. The octopus will bite when stepped on or provoked. Blue-ringed octopus poison has no antivenom and can kill an adult human within minutes.
Poison dart frogs have an alarmingly bright color scheme, which is nature's way of warning predators to stay away. They are among the most poisonous animals on earth because they are covered in enough poison to kill between 10 and 20 men.
