BOY PLAYING WITH KING COBRA..DANGER

The king cobra (Ophiophagus hannah), also known as the hamadryad, is a venomous snake species in the family Elapidae, endemic to forests from India through Southeast Asia. It is threatened by habitat destruction and has been listed as Vulnerable on the IUCN Red List since 2010.[1] It is the world's longest venomous snake.[2] Adult king cobras are 3.18 to 4 m (10.4 to 13.1 ft) long. The longest known individual measured 5.85 m (19.2 ft).[3] Despite the word "cobra" in its common name, this species does not belong to genus Naja but is the sole member of its own. It preys chiefly on other snakes and occasionally on some other vertebrates, such as lizards and rodents. It is a dangerous snake that has a fearsome reputation in its range,[4][5][6] although it typically avoids confrontation with humans when possible.[4] The king cobra is a prominent symbol in the mythology and folk traditions of India, Sri Lanka and Myanmar.[7][8] It is the national reptile of India.[9
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 3.18 to 4 m (10.4 to 13.1 ft) long. The longest known individual measured 5.85 m (19.2 ft).[3] Its belly is cream or pale yellow.[12] It has 17 to 19 rows of smooth scales. Ventral scales are uniformly oval shaped. Dorsal scales are placed in an oblique arrangement.[13] Males have 235 to 250 ventral scales, while females have 239 to 265. The subcaudal scales are single or paired in each row, numbering 83 to 96 in males and 77 to 98 in females.[citation needed]

Juveniles are shiny black with narrow yellow bands (can be mistaken for a banded krait, but readily identified with its expandable hood). The head of 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 needles. The average lifespan of a wild king cobra is about 20 years.[12]

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.[citation needed]

The king cobra typically weighs about 6 kg (13 lb). The longest known specimen was a captive one at the London Zoo, and grew to around 18.5 to 18.8 ft (5.6 to 5.7 m) before being euthanised upon the outbreak of World War II. The heaviest wild specimen was caught at Royal Island Club in Singapore in 1951, which weighed 12 kg (26 lb) and measured 4.8 m (16 ft), though an even heavier captive specimen was kept at New York Zoological Park and was measured as 12.7 kg (28 lb) at 4.4 m (14.4 ft) long in 1972.[citation needed] Some viper species, such as the eastern diamondback rattlesnake and the Gaboon viper, often much shorter in length but bulkier in build, rival the king cobra in average weight.[14]
