Of the more than 600 species of venomous snakes found on Earth, only about 200 can do any real damage to humans, according to the World Health Organization. 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.
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.
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 greatly in size depending on their preferred type of prey.
