King cobras live mainly in the rain forests and plains of India and Southeast Asia. They are comfortable in the trees, on land and in water, feeding mostly on other snakes with the rat snake being their preference. King cobras can reach 18 feet in length, making them the longest of all venomous snakes. Fortunately for us, they are reclusive creatures that will make every attempt to avoid humans.
When confronted, though, a king cobra transforms into a lethal adversary. It can raise a third of its body straight off the ground, looking the average person directly in the eyes, and still advance forward to attack. The intimidating snake will flare out its iconic hood and produce a frightening hiss that sounds a lot like a dog's growl. A single bite contains enough venom to bring down an elephant.
Scientists are just now beginning to understand how intelligent these snakes really are. The king cobra is believed to possess exceptional memory. According to a myth, the picture of the killer of a king cobra stays in the eyes of the dead snake, that frozen image is later memorized by the snake's partner and is used to hunt down that killer for revenge.
