Research indicates the King Cobra to be the most intelligent snake species. Physically the brain is proportionally larger and their behavior is more complex. The mother king will deposit her eggs, then tend the nest till they hatch. There is a stratified King Cobra society. Kings stand to face each other, enemies, and food. Tap a king on the head, and they will “bow to you.” This behavior is very uncommon in the snake world. I do not think there is any question that kings are more intelligent then any other snake.
