Ten fun facts
it does not belong to the genus Naja: it is the only species in the genus Ophiophagus, which means snake eater.
its fangs are short for the size of the animal, rarely exceeding half an inch in length.
it can be recognized by two large scales behind its head, called occipitals, which other cobras do not have.
it is the only snake in the world that builds a real nest, piling up leaves and branches for its eggs.
it hunts during the day, while almost all other land snakes are active at dusk or during the night.
it always swallows its prey head first, so the scales do not stick up and damage its digestive tract.
its prey defends itself by remaining still, with its head tucked under its coils where the snake cannot bite it.
it can chase an intruder while keeping the front part of its body raised, without ever lowering its head.
it ranges up to 6,500 feet in elevation and also frequents sewers, irrigation canals, and human gardens.
in some villages in Myanmar, people practice cobra kissing, a ritual that causes many dangerous accidents.
