Cobras are some of the most dangerous and venomous snakes found mostly in Africa and Asia. They can range in length from 8 feet to just over 18 feet. According to National Geographic, one bite from a king cobra has enough toxin to kill 20 people or even an elephant. Most cobras, however, are shy and try to stay away from humans.
Inland Taipan has the most toxic venom of any land snake in the world. The maximum yield recorded for one bite is 110mg, enough to kill about 100 humans, or 250,000 mice! With an LD/50 of 0.03mg/kg, it is 10 times as venomous as the Mojave Rattlesnake, and 50 times more than the common Cobra.
