The Elapid snake family is home to some of the most venomous snakes in the world, including cobras, sea kraits, mambas, and many more.
These snakes are similar to the colubrids in their body structure, with one large lung, and a complete absence of legs (unlike the constrictors). However, these are front fanged venomous, and their venom is stronger.
King cobras are one of the most intelligent snakes in the world, and even though their venom is deadly, it is very rarely used on humans. Almost all of cobra bites to humans are dry bites.
