King Cobra - Worst Snake to be Bitten By in Thailand. Death can occur in 10 minutes.

King Cobra – Largest Venomous Snake in World

Large Thailand King Cobra head
Ophiophagus hannah. Very deadly. Grows almost to 6m. Eats other snakes primarily. If bitten, may die within 10-20 minutes.

Thais say: Thai language sounds like Ngoo how chang, or ngoo chong ahng. There are many names for this snake.

Length: Max length about 5.8 meters. The presenter at the Saovabha Snake Farm in Bangkok said the largest king was caught in Nakhon si Thammarat in Thailand’s south, near Surat Thani province.

Range: All over Thailand and most of Southeast Asia.

Notes: I’ve seen just three in the wild. One I saw in a park – just the tail as it crossed the road behind me. I’m guessing it was a 8 meter King. I know, but I’m not joking. The tail was absolutely massive, long and thicker by nearly double that of other 5-meter kings I’ve seen many of. This was possibly the biggest King Cobra in the world. Kings are all over Thailand and can be found anywhere near houses, or really – anywhere. They are tremendously strong and smart animals. Please give the snake a large space and do not poke it with a stick. They are very fast moving. Juvenile king cobras can also kill you. Their venom is every bit as toxic as adults.

Habitat: Like many types of habitat. Dense forest near water and open grasslands.  Love bamboo thickets for a nest. Ideal cover is a web of small bamboo growing about a meter high with soft bamboo leaves underneath. The King I found last night was up a limestone mountain around 100 meters elevation. In Thailand they are often found wherever rat snakes might be found because they seem to prefer them.

Kings seem to prefer mountains. The other two I found were also at some elevation (200 m and around 500 meters).

King cobras are usually terrestrial, but have been found many times in trees.

Active Time? The snake is mainly diurnal – found active during the daytime, but can also be active also at night.

Food: King cobras eat other smaller snakes primarily, but also will eat monitor lizards. Occasionally they’ll eat other king cobras, pythons, lizards, birds, rodents. I saw a 5 meter long king attempting to eat a 2.5 meter reticulated python. The King appeared intimidated by the strength of the python – it’s no pushover. Here is a photo of a 3 meter king eating a 2 meter red tailed racer snake.

Defensive Behavior: Lifts its head off the ground sometimes by as much as 4-5 feet, and flattens out the neck. The hood of a King cobra doesn’t flare as wide… but, a big King will scare you much more because they can be 5 times as long as the monocled or other cobras! These snakes are not usually that afraid of people, and move slowly to ‘escape’ if they move away at all. Last night I moved a 4 meter king off some steps at a local temple so people could pass. It was not in ANY hurry to get away, and it came at me a couple of times. Impressive snakes, and be very afraid… I know a man personally, his brother was bitten on the chest and died in less than 10 minutes on the way to hospital.

Venom Toxicity: Very toxic, but monocled cobras (Naja kaouthia) and kraits (genus Bungarus) are more potent on the LD50 scale. The power of the King is in the volume of venom it can inject in one bite – maximum around 7ml! Kings can kill elephants with a bite.

Antivenom: There is a specific antivenin for the king cobras, but if the hospital you are at does not have it there is an alternative. Tiger snake antivenin can also work well.

Offspring: Lay eggs which they stay with in the nest until ready to hatch. When the eggs start to hatch the mother leaves because it eats other snakes primarily – and would likely eat the young. The young are fast, and deadly from the time they hatch. Juvenile king cobras from Thailand have yellow bands across their black bodies and heads. They look radically different from adult king cobra snakes. There is a danger of mistaking them for mangrove cat snakes (Boiga melanota).

Notice the light band across the back of the mid-body (right) ? Until the King flares his hood you can tell it’s a king by those bands. In addition, the head is very distinctive, and large compared to any other snake except a Python.

The kings in these photos are all beat up from bashing their faces against the cages at a snake show in Thailand. In the wild they are so beautiful… majestic… amazing snakes. I was so glad to see my first one  in the wild last night. Even better to interact with it… Gotta love Thailand!
