Key Features
Largest venomous snake in the world, growing to a length of almost 16.5’. Preys on other snakes (even venomous species) by subduing them with its highly potent venom and swallowing them whole. Rears its head off the ground and spreads its neck into a “hood” to threaten intruders and predators.
King Order - squamata

King Cobra
The heavy and muscular king cobra can kill other snakes with its powerful venom; it uses its menacing hood to warn off other animals.
Tongue - The cobra detects prey by flicking its tongue out to collect scents from the air. Inside the mouth, the tongue passes over the Jacobson’s organ - a receptor that analyzes different scents.
Skin - Its skin is olivegreen, tan or black with faint, pale yellow crossbands down the length of the body. The underbelly is cream or pale yellow.
Lifecycle
Fangs - The sanke’s hollow fangs grow to a length of 1/2”. It punches them into its prey, like hypodermic needles, and injects a powerful venom.
Head - The cobra can dislocate its jaw to engulf large prey. The venom glands lie behind the eyes.
The combination of immense body size and plentiful, potent venom makes the king cobra a formidable hunter, and helps it defend itself when threatened.

Did You Know?
The cat-sized Indian mongoose can survive a dose of cobra venom that would kill eight rabbits. The king cobra’s generic name means ‘snake-eater.’ Snake-charmers usually perform with the Asian cobra, instead of the king cobra. The Asian cobra is more common, is smaller and has a broader, more impressive hood.
Hood - The cobra spreads its neck to form a hood with a double chevron marking on the back.

Habitat Secretive snakes Bamboo thickets provide cobras with shelter, nests and hunting ground.
The king cobra is found mainly in Southeast Asia, where it frequents clearings, bamboo thickets and the borders of undisturbed forest. In northern India, the cobra inhabits dense highland forests, up into the foothills of the
Himalayas. Although it can climb trees with ease, the cobra rarely does so unless pursuing prey. In its range, the king cobra is also found on farmland and in the outlying parts of villages and abandoned buildings. As forest is cleared

1. Track. Flicking its tongue in and out for scent samples in the air, the cobra detects a small python. It then tracks the prey by sight. 2. Coil. Slipping silently through the grass, the cobra approaches its prey undetected. It coils its forequarters in preparation for a rapid strike. 3. Strike. In a single, smoothe action, the cobra whips its head forward and sinks its fangs into the python’s neck, injecting venom. 4. Devour. When the venom has paralyzed the python, the cobra dislocates its jaw and ‘walks’ them over the victim, consuming it whole.
In January the male king cobra starts to find a mate, tasting the air with his flickering tongue. When he tracks down a female, he approaches her cautiously and rubs his chin over her body. The rough skin on his neck pacifies her and stimulates her into mating. About a month after mating, the female seeks out a secluded spot, such as a bamboo thicket, where she excavates
a shallow, circular depression in the ground up to about 3’ in diameter. There, she deposits about 40 to 50 eggs and remains on, or near, the nest until they hatch, 70-77 days later. The female actively defends her nest site: female cobras have been reported even to chase intruders away from their eggs. The male, too, may stay close by for a while to assist in defense. When they emerge,

the hatchlings are 12”-25” long. Their venom, though produced in small quantities, is just as powerful as an adult’s. As soon as all of the young snakes have hatched, the female leaves them to look after themselves.
Breeding Potential The cobra can breed at about four years old.

Food & Hunting The king cobra preys on other snakes and lizards. It will attack venomous snakes, such as kraits or other cobras, and non-venomous ones, such as small pythons. The cobra tracks prey by sight and by ‘tasting’ the air with its tongue. It strikes rapidly, sinking fangs into the
prey and injecting a massive dose of venom that paralyzes the nervous system. Despite the quantity and potency of the venom, it may take two hours or more to subdue a reptile, whose body circulates the venom at a slow rate. When the cobra bites a warm-bloode animal in defense, such as
Behavior The king cobra is active by day but is rarely seen by humans. It can move quietly through vegetation and deliberately avoids disturbances. If an intruder startles the king cobra, however, it rears its head, spreads its neck to form a menacing hood and sways from side to side, hissing. It can sway for several minutes and, unique
among cobras, can also move forward in this position. This is intended to intimidate and repel the intruder without the cobra having to strike. Occasionally, an intruder doesn’t retreat, and if the cobra is provoked or highly alarmed, it may bite to protect itself. The cobra’s bite is little use against birds of prey, which

swoop from behind to strike the snake’s head. By lying low in thickets, the cobra can hide from these enemies.
Related Species The king cobra is related to six species of the genus Naja, including the Egyptian cobra, N. haje, found across Africa; the forest cobra, N. melanoleuca, in African rainforests south of the Sahara; and the Asian cobra, N. naja, which has a distinctive hood marking that looks like a pair of spectacles. The Asian cobra has ten subspecies, including the Indian cobra, N. naja naja.
Conservation
Part of the king cobra’s forest habitat is disappearing. In eastern Asia, the snake is also killed to use in traditional medicine and to eat. Although the widespread Asian cobra is responsible for more human deaths, and suffers greater persecution from humans, the king cobra is still greatly feared and is usually killed wherever it is found. Although not yet endangered, the king cobra has few allies and its population is likely to decline in the future.
Creature Comparisons
Coral Snake
The king cobra belongs to the family Elapidae, sometimes called the cobra family. There are over 200 species of elapid around the world, except Antarctica and Europe. All are venomous and have short, fixed fangs, but differ in habit and appearance. The coral snake flaunts bold colors, which keep animals away; the death adder hides under sand by day and hunts by night; and the green mamba rests hidden tree foliage.
