When you think about deadly creatures, Australia seems to have the worst venomous animals on Earth. These dangerous creatures can be found both on the ground and in the ocean, so Australian citizens and tourists have to move with care on the territory.

The stonefish, as it is explained in this video, is one of those creatures that kill by injecting their venom in the swimmers and scuba divers that have the misfortune to be in the wrong place at the wrong time.

The video, published on the Youtube channel SmarterEveryDay, shows what happens when people pass on any of the 13 venomous dorsal spines of the fish.
