King Cobra
The longest venomous snake builds nests, raises young — and actively avoids confrontation with anything too large to eat

Overview
King cobras are the world's longest venomous snakes, reaching 5.5 meters, and their venom can kill an elephant. They're also among the most behaviorally sophisticated snakes — building nests, showing parental investment rare in snakes, and almost always fleeing from human encounters rather than attacking.
Friendly fact
King cobra mothers guard their nest without eating for the entire incubation period. The mother typically leaves just before hatching — to avoid eating her own offspring. It's one of the most striking examples of parental instinct in snakes.
Fascinating facts
- 1
King cobra venom is not the most potent of any snake — but the volume delivered in a single bite is so large it can kill an elephant or 20 people. The dose is the danger.
- 2
King cobras are the only snakes that build nests — the female constructs a vegetation mound, lays eggs inside, and guards them for months until hatching.
- 3
King cobras feed almost exclusively on other snakes, including venomous species — they're specialist predators occupying a niche most snakes cannot.
- 4
A raised hood is an assessment and warning posture, not a pre-attack signal — it's more often followed by retreat than by striking.
- 5
King cobras 'hear' through vibrations — their jaw touching the ground detects footsteps at distances that give them ample warning to retreat.
Myth vs. Reality
Myth
King cobras are aggressive man-hunters.
Reality
King cobras almost always retreat from humans given the option. Most bites occur when a snake is cornered or accidentally stepped on.
Myth
The raised hood means it's about to strike.
Reality
The hood is an awareness and warning display. A hooded king cobra is evaluating the situation — retreat is the most common outcome.
