Of the more than 600 species of venomous snakes found on Earth, only about 200 can do any real damage to humans. Here are six of the deadliest snakes on the planet.
1. Saw-scaled viper
This viper, Echis carinatus, which inhabits parts of India and the Middle East, doesn't possess the strongest of venoms, but is responsible for more human deaths annually than any other snake, partly because it's often found in populated areas. Twelve hours after being bitten by the saw-scaled viper, a patient's blood becomes incapable of coagulating. The patient bleeds and develops renal failure. Currently, there is no antivenom for the viper.
2. King cobra
Wondering which snake can bring down an elephant? The king cobra (Ophiophagus hannah) delivers enough neurotoxins to kill an Asian elephant, as well as about 50 percent of the humans it bites. Reaching 18 feet (5.5 meters) in length, the king cobra is also the world's longest venomous snake. If bitten by an adult king cobra, it will not be an easy death. The neurotoxic venom disrupts communication between nerve cells, bringing about paralysis of muscles around the lungs and disturbing cardiac rhythm.
In short, you suffocate to death or experience fatal cardiac collapse. The process takes about 30 minutes if you received a full dose. That will be half an hour filled with panic as you desperately try to inhale.
3. Tiger snake
This deadly snake (Notechis scutatus) inhabits southern Australia and Tasmania, and kills victims with a potent mixture of neurotoxins, coagulants, hemolysins and myotoxins. Interestingly, these snakes vary in size depending on their preferred type of prey. If bitten, you will most likely suffer from blurred vision, diplopia and difficulty swallowing followed by cardiac arrest.
4. Inland taipan
This reptile (Oxyuranus microlepidotus) is often referred to as the "fierce snake," and its bite can kill a human being in less than an hour. Found in Australia, it is one of the deadliest snakes on the planet, its paralyzing venom causes hemorrhaging in blood vessels and muscle tissues.
5. Faint-banded sea snake
Many believe this water snake to be the most venomous snake in the world. The bite of Hydrophis belcheri is said to be 100 times more deadly than that of its compatriot, the inland taipan. One bite from this snake has enough venom to kill 1000 humans.
6. Black mamba
The fastest snake in the world is also one of the deadliest. The black mamba (Dendroaspis polylepis) can move at speeds of up to 12.5 miles per hour (5.5 meters per second), and its bite can kill a human being in less than 30 minutes. This snake is known for using its lethal fangs to repeatedly stab those unfortunate enough to get in its way, with each bite injecting a deadly amount of neurotoxic venom. Found in Africa, if bitten by this snake, you will encounter cardiac arrest and brain injury.
