The king cobra Ophiophagus hannahalso known as the hamadryadis a venomous snake species in the family Elapidaeendemic to forests from India through Southeast Asia.
The longest known individual measured 5. It preys chiefly on other snakes and occasionally on some other vertebratessuch as lizards and rodents. It is a dangerous snake that has a fearsome reputation in its range,    although it typically avoids confrontation with humans when possible. Mature king size king cobra was described and drawn by the Danish naturalist Theodore Mature king size Cantor inwho gave it the scientific name Hamadryas hannah.
Cantor had "Mature king size" specimens from the Sundarbans and one caught in the vicinity of Kolkata. Ophiophagus hannah belongs to the monotypic genus Ophiophagus in the family Elapidaewhile most other cobras are members of the genus Naja. They can be distinguished from other cobras by size and hood. King cobras are generally larger than other cobras, and the stripe on the neck is a chevron instead of a double or single eye shape that may be seen in most of the other Asian cobras.
Moreover, the hood of the king cobra is narrower and longer.
These are behind the usual "nine-plate" arrangement typical of colubrids and elapids, and are unique to the king cobra. The skin of king cobra is dark olive or brown with black bands and white or yellow crossbands. The head is black with two crossbars near the snout and two behind the eyes. Adult king cobras are 3. Ventral scales are uniformly oval shaped. Dorsal scales are placed in an oblique arrangement. The subcaudal scales are single or paired in each row, numbering
Mature king size to 96 in males and 77 to 98 in females.
Juveniles are shiny black with narrow yellow bands can be mistaken for a banded kraitbut readily identified with its expandable hood. The head a mature snake can be quite massive and bulky in appearance, though like all snakes, it can expand its jaws to swallow large prey items.
It has proteroglyph dentition, meaning it has two short, fixed fangs in the front of the mouth, which channel venom into the prey like hypodermic Mature king size. King cobras are sexually dimorphic in size, with males reaching larger sizes than females, which is an unusual trait among snakes whose females are usually larger than males. The length and mass of the snakes highly depend on their localities and some other factors.
The longest known specimen was a captive one at the London Zooand grew to around King cobra populations have dropped in some areas of its range because of the destruction of forests and ongoing collection for the international pet trade. A king cobra, Mature king size other snakes, receives chemical information via its forked tonguewhich picks up scent particles and transfers them to a special sensory receptor Jacobson's organ located in the roof of its mouth.
Its intelligence  and sensitivity to earth-borne vibration are also used to track its prey. Following envenomationthe king cobra swallows its struggling prey. King cobras, like all snakes, have flexible jaws.
The jaw bones are connected by pliable ligaments, enabling the lower jaw bones to move independently. This allows the king cobra to swallow its prey whole, and swallow prey much larger than its head. King cobras are able to hunt throughout the day, but are rarely seen at night, leading most herpetologists to classify them as a diurnal species.
The king cobra's generic name, Ophiophagus is a Greek -derived word that means "snake-eater". Its diet consists primarily of other snakes, including rat snakesMature king sizeand even other venomous snakes such as various members of the true cobras and the krait. When food is scarce, it also feeds on other Mature king size vertebrates, such as lizardsbirds, and rodents.
In some cases, the cobra constricts its prey, such as birds and larger rodents, using its muscular body, though "Mature king size" is uncommon. When annoyed, this species quickly attempts to escape and avoid confrontation. When alarmed, it rears up the anterior portion usually one-third of its body when extending the neck, showing the fangs and hissing loudly.
When Mature king size its body, the king cobra can still move forward to strike with a long distance  and people may misjudge the safe zone. This snake can deliver multiple bites in a single attack,  and adults are known to bite and hold on. Many victims bitten by king cobras are actually snake charmers.
Some scientists believe that the temperament of this species has been grossly exaggerated. In most of the local encounters with live, wild king cobras, the snakes appear to be of rather placid disposition, and they usually end up being killed or subdued with hardly any hysterics. These support the view that wild king cobras generally have a Mature king size temperament, and despite their frequent occurrence in disturbed and built-up areas, are adept at avoiding humans.
Naturalist Michael Wilmer Forbes Tweedie felt Mature king size "this notion is based on the general tendency to dramatise all attributes of snakes with little regard for the truth about them. If the snake were really habitually aggressive, records of its bite would be frequent; as it is they are extremely rare. If a king cobra encounters a natural predator, such as the mongoosewhich has resistance to the neurotoxins,  the snake generally tries to flee.
If unable to do so, it forms the distinctive cobra hood and emits a hiss, sometimes with feigned closed-mouth strikes. These efforts usually prove to be very effective, especially since it is much more dangerous than other mongoose prey, as well as being much too large for the small mammal to kill with ease.
A good defense for anyone who accidentally encounters this snake is to slowly remove a shirt or hat and toss it to the ground while backing away. The hiss of the king cobra is a much lower pitch than many other snakes and many people thus liken its "Mature king size" to a "growl" rather than a hiss. Comparative anatomical morphometric analysis has led to a discovery of tracheal diverticula that function as low-frequency resonating chambers in king cobra and its prey, the rat snake, both of which can make similar growls.
The female is gravid for 50 to 59 days, after which she builds a nest, lays 12 to 51 eggs and guards it during the incubation
Mature king size of about 51 to 79 days. The king cobra is unusual among snakes in that the female is a very dedicated parent.
For the nest, the female scrapes up leaves and other debris into a mound, and stays in the nest until the young hatch. She guards the mound tenaciously, rearing up into a threat display if any large animal gets too close.
When the eggs start Mature king size hatch, the female leaves the nest. The baby king cobra's venom is as potent as that of the adults. They may be brightly marked, but these colours often fade as they mature.
They are alert and nervous, being highly aggressive if disturbed. The venom of the king cobra consists primarily of neurotoxinsknown as the haditoxin with several other compounds. If the envenomation is serious, it progresses to cardiovascular collapse, and the victim falls into a coma.
Death soon follows due to respiratory failure. Two types of antivenom are made Mature king size to treat king cobra envenomations. The Red Cross in Thailand manufactures one, and the Central Research Institute in India manufactures the other; however, both are made in small quantities and, while available to order, are not widely stocked.
Snakebites from this species are rare, and most victims are snake handlers. The species is classified as Vulnerable by the IUCN due to pressure from harvesting for meat, skin and use in traditional medicine, and because of increasing loss of habitat to deforestation. A ritual in Myanmar involves a king cobra and a female snake charmer. The charmer is a priestess who is usually Mature king size with three pictograms and kisses the Mature king size on the top of its head at the end of the ritual.
