The King cobra (Ophiophagus hannah) is probably best known as the species of choice for the South Asia snake charmers. Even though cobras can hear, they are actually deaf to all ambient noises, instead they sense the ground vibrations.
The snake charmer's flute entices the cobra by its shape and movement, not by the music or sound it produces.
It seems just a bit unfair and menacing that the King Cobra, the snake that can and will literally "stand up" and look a full-grown human in the eyes would also be among those with some of the most potent venom on the planet, but that's what the famous King Cobra is all about.
King cobras live in Southeast Asia mainly in the plains and rain forests of India where they are abundant and revered in some places, southern China, Malaysia and the Philippines. Their coloring can vary greatly from region to region, from blackish brown with white and ivory in China to yellow and black in India.
The King cobra can reach up to 18 feet (5.5 meters) in length, making them the longest of all venomous snakes. It is a relatively slender snake, it will typically weigh between 15 to 20 pounds.
Male snakes are bigger and thicker than the females, they have a life expectancy of around 20 years. They feel comfortable both in the trees, on land, and in water and are both good climbers and swimmers.
When confronted or harassed, they will raise up to one-third of their body straight off the ground and will still be able to move forward to attack. They will also show off their iconic hoods and emit a loud bone-chilling hiss that resembles almost a growling dog.
Fortunately, the King Cobra snake is shy by nature and will avoid humans at all costs, whenever possible, but they are notably aggressive when cornered.
Their venom is not the most potent among venomous snakes, but the shear amount of neurotoxin they deliver in a single bite, up to 0.2 ounces (seven milliliters) of a fluid, is enough to kill 20 people, or even an elephant.
Their bite snake causes instant pain, vertigo, blurred vision and paralysis and soon after the respiratory and cardiovascular system will fail inducing coma and result in death.
Diet / Feeding
The species scientific name, "Ophiophagus" literally means "snake eater", so the basic food of the King Cobra as it name suggests are other snakes both venomous and non-venomous.
However if the opportunity arises amphibians, rodents, small mammals, other reptiles and birds or eggs are also part of their diet. Because of their extremely slow metabolism after ingesting a large prey they can go months without feeding again.
The species mating season runs from January to April, at that time the female and male will perform a nuptial dance in which they face each other with their heads held high. This is the only snake species in the world that builds a nest for their eggs, made out of leaves, grass and thin branches.
They will guard the nest ferociously until their hatchlings emerge. The female lays an average of 24 eggs, and will remain coiled around the eggs until they hatch, which may take between 60 to 80 days.
Conservation / Threats
The King Cobra isn't listed by the IUCN as in danger of extinction but despite this their populations are declining in some areas of it's natural range, in the most part because of the destruction of forests.
