There are two animals which could top the list of the most poisonous animals in the world.
The King Cobra is considered the world's most venomous snake, growing up to 5.6 m (18.5 ft) in length.
It is also called Ophiophagus which also means "snake-eater”, because it eats other snakes. One single bite of this deadly snake can easily kill a human.
This snake is even capable of killing a full-grown Asian Elephant within 3 hours if the larger animal is bitten in a vulnerable area such as the trunk.
During a bite, venom is forced through the snake's half-inch (1.25 cm) fangs into the wound, and quickly attacks the victim's central nervous system, inducing severe pain, blurred vision, vertigo, drowsiness, and paralysis. Envenomation progresses to cardiovascular collapse, and the victim falls into a coma. Death soon follows due to respiratory failure..
