King cobras are venomous snakes that live in South and Southeast Asia. The reptile makes its home in forests and swamps. It can grow up to 18 feet long. And the animal's toxic bite is powerful enough to kill an elephant.

Cobras eat small mammals, lizards, and birds. They can also end up on the dinner menu—the snake is a favorite meal of the mongoose, a kind of mammal.

When facing predators, king cobras try to act like tough guys. They often expand ribs and muscles on both sides of their necks to create what’s called a hood. The hood makes the snake appear extra-big.

While cobras can become aggressive when hungry or threatened, they know how to make their families feel at home. These are the only snakes that build nests for their eggs. How ssssweet!
