These are great snakes for a couple of reasons. Number 1 – their colors. This snake looks like Christmas – right? Amazing oranges, greens, and blacks make it very unique.
Number 2? They fly. Well, they glide very far when they jump from a high vantage point. They can glide dozens of meters – and probably more. These snakes are limited only by how high they are when they jump. Typically they use their gliding ability to travel from tree to tree in search of prey, or to elude capture by a predator.
Name: Chrysopelea paradisi. Paradise Tree Snake. Also called “Paradise flying snake.”
Length: As long as 1.2 meters (almost 4 feet)
Appearance: Very similar in all aspects to C. ornata with the exception of scale coloration. C. paradisi has black scales on the neck and body which have a green or yellow dot in the center of each scale. Scales on the dorsal near the vertebral column may have an orange or reddish coloration. Some call this the flower pattern. Great variation occurs as to how much orange is evident on the dorsal area – some have on the head, and completely down the body to the tail. Others have some orange on the head and a little bit on the neck, and none of the rest of the body.
Range: Thailand-wide. This one was found in Krabi province at sea-level in a handbag shop at the beach. We’ve found them in rainforest near a Thailand resort as well.
Habitat: Bushes, ground, trees, roofs. They are often found in palm tree fronds. I have found them there as well as small trees with big leaves and a lot of open area so they can see – presumably. I have found them as high as 500 meters vertically up a mountain in Thailand, and at sea level. Recently we found one 7 meters up a large tree on a hot sunny day.
Active Time? Diurnal – active during the day in trees and bushes, and occasionally on the ground.
Food: House geckos, Tokay geckos, lizards, bats, and frogs.
Defensive Behavior: They bite very quickly, but have small mouths and teeth. There has been no medically significant case of envenomation mentioned in the literature. They are considered harmless for humans and probably pets over the size of a cat.
Venom Toxicity: Weak for humans. Effective for geckos, frogs and bats. These are rear-fanged colubrids and a prolonged bite could cause swelling and pain at the bite site.
Offspring: They produce eggs which hatch during May/June in Thailand.
Notes:C. Paradisi is distinguished from C. ornata by the orange/red coloration at the top of the body, sometimes at the head, sometimes more of the body is colored, and sometimes the entire head and body are covered in the red flower like scale patterns.
Kingdom: Animalia Phylum: Chordata Class: Reptilia Order: Squamata Suborder: Serpentes Family: Colubridae Subfamily: Colubrinae Genus: Chrysopelea Species: C. paradisi Binomial name – Chrysopelea paradisi Classified by Boie, in the year 1827
These are yellow and black kraits here in Thailand. In some other part of the world (Borneo) they are black and white. There are also “Blue Kraits“ aka “Malayan Kraits” which are black and white. And the really incredible looking Red-headed Krait which looks nothing like either of them.

Bungarus Fasciatus (Banded Krait)
Thais say: (ngoo sam lee-um, or ngoo kan plong) This is a bit confused in Thailand where in southern Thailand any viper is known as Ngoo sam lee-um. Lee-um means triangle, and so some people confuse triangle-shaped heads of the vipers with triangle cross-section of the kraits.
Length: average 1.5 m up to 2 m (about 6.5 feet) In Thailand they don’t usually reach a full 2 meters, but I have seen one that was just over 2m.
Range: All over Thailand and most of Asia. Never found in Krabi province, oddly enough.
Notes: Banded kraits are secretive, meaning they are mobile at night and prefer grass or other greenery to hide them. I have seen a few dead on the roads – but I don’t go digging up ratholes or termite mounds. I may start if I don’t find one soon. I’ve been looking for three years to find a krait with yellow and black bands like these.
At dinner last night I was looking around a small restaurant with many ponds, for snakes. I asked the owner’s son if they had seen any. He said, Ngoo Sam lee-um. That could be the one. I’ll get their permission for some late-night herping and try to bag one. I’m sure they’ll appreciate it. This restaurant is located on a small hill close to sea level in southern Thailand. There are many frogs at the ponds, and probably many snakes too.
Update 2021- I’ve been to that restaurant numerous times and not had a call from them about this krait. I am not sure they have been found in Krabi. I have never found road kill B. fasciatus here in Krabi. I have found a large 2 meter dead on the road banded krait in Surat Thani on the main highway leading to Krabi.
Habitat: This Thailand krait lives on the ground and in rat holes and termite mounds, under stumps or rocks and in other cool, damp places. Recently I saw photos of one in some limestone rocks here in Thailand. They prefer wide-open areas near water. They have been found as high as 1,524 meters in Malaysia and about 2,300 meters in Thailand.
Active Time? The snake is mostly nocturnal and is quite active at night. Most bites occur at night, as the kraits move close to people sleeping – usually on the floor, and probably the person moves and the krait bites. More dangerous at night, during the day they are not biters. These kraits are common in the northeast Thailand provinces. Recently a six-year-old boy was bitten and could not be revived. The snake had come up into their home in Surin to escape some flooding.
Food: Other snakes almost exclusively – rat and cat (Boiga) snakes. In captivity, I have seen them eat the following live snakes: Calloselasma rhodostoma, Chrysopelea ornata, and Gonyosoma oxycephalum. One noted herpetologist states that these kraits don’t like to eat water snakes. Will also eat rats, mice, frogs, lizards if snakes cannot be found.
Defensive Behavior: The banded krait is slow acting during the day, lethargic, and usually not interested in striking. However, it can protect itself quite well – it is a strong biter and has been recorded as killing a large type of cattle 60 minutes after a bite.
Venom Toxicity: Very toxic. Deadly. This yellow/black banded krait from Thailand appears to have venom that is very toxic to humans. The typical LD-50 studies to assess the toxicity of venom in mice, rate this as a very toxic venom as well. These snakes rarely bite during the day, but if they do, they can transfer enough venom to kill you. I read about a person dying in 30 minutes, and another dying in 15 hours.
A famous American herpetologist, Joe Slowinski, was killed by a baby krait (Bungarus multicinctus) in Burma while on a remote expedition. He finally succumbed after 30 hours. They can be quite deadly. The cause of death is that your muscles are paralyzed and your diaphragm can’t work any longer to pull oxygen into your lungs.
Kraits are very deadly in this regard. However, if you are able to get to a hospital with a ventilator you will likely be OK. There is no specific antivenin for snake bites from this snake, but polyvalent venom is used – which can also treat bites from Naja kaouthia and Ophiophagus hannah.
Interesting to note… when fed on a live garter snake the krait venom acts instantly to cause death. Apparently krait venom is very efficient with snakes – the krait’s primary diet.
Handling: The banded and Malayan blue kraits are not known to bite during the daytime. However, at night time they bite rather easily, as evidenced by the numerous krait bites that occur at night to people usually laying down to sleep on the floor either outdoors or in their homes with the door open. I would never handhold kraits like the man is doing in the photo above. The krait venom is so toxic, it’s just not worth the risk – however small.
Update: I was contacted by a man who was bitten by this same type of krait during the day at an impromptu show at a bar in Bangkok during the daytime. It bit his arm. He was lucky to live and had lingering effects for more than two years after the bite.
Antivenin: Polyvalent. It is advised by experts to get antivenin in your bloodstream for krait bites before you have symptoms because once symptoms develop you may have lost nerve functioning that will likely not return.
Offspring: Mating in March-April and 4-14 eggs laid about 60 days afterward. The mother krait remains with the eggs for another 60 days before they hatch. Baby kraits are about 30cm long at birth and have venom. I couldn’t find in the literature whether the mother left the eggs as they started hatching – so she didn’t eat them herself or not. The King Cobra does this instinctively because it also eats other snakes.

A common phrase and saying in the USA is to say someone is a real SNAKE IN THE GRASS. Why is that? What does it mean?
The Meaning of “Snake in the Grass”
Snakes cause fear in most people because they just don’t understand them. I mean, there isn’t that much to understand on the surface, they are animals that eat other animals and they prefer to stay FAR away from human beings. They have no reason to bite humans except that we make them fearful. OK, that’s that.
A snake in the grass is a saying to caution someone against someone’s ulterior motives, personality, intentions, etc. A snake in the grass is supposed to mean someone with bad intentions, someone who is a sneaky devil who is going to pull something over on someone who is unsuspecting.
A snake lays in the grass without bothering anyone. When someone steps on it, and the snake bites, the person thinks that snake was just WAITING there in the grass to bite someone. Hence the saying, like a snake in the grass.
Snakes are so misunderstood. The problem in many places, like Thailand, is that we have SO MANY snakes that it’s impossible to educate the public about this snake being potentially dangerous and that one being completely harmless. Even among people who know something about snakes, snake hobbyists, there are often times when a snake is hard to identify. It takes a long time to get up to speed with exactly what defines a dangerous snake in the grass, so to speak.
Origin of the Snake in the Grass Phrase?
The Roman poet “Virgil” in 37 b.c. in his poem with the Latin words “Latet Anguis in Herba.” Seriously. Before Christ was born, this guy made up the saying to mean a dangerous snake (venomous snake) waiting in the grass to bite someone.
In the USA, the phrase was first used in the title of a book by Charles Leslie, called “Snake in the Grass” in 1696.
For our purposes here, snake in the grass just means a snake in the grass. A treacherous person, one who means harm, is known as a deviant.
The oriental whip snake is a very common rear-fanged venomous snake found here in Thailand’s rain forests. You can find these snakes in the trees during the day, I have even seen them crossing my path twice on trips up a small local mountain in southern Thailand.
The beauty of these snakes is legendary. There are green, yellow, or grey phases of this snake, all of which are spellbindingly beautiful. The juvenile whip snakes are often brown or yellow.
Ahaetulla prasina (Oriental Whip snakes)
Thai Language: ngoo kee-ow hoo-uh jing joke pa
Length: Up to 190 cm. Girth: The body is finger thin, tapering to a very thin pencil-width neck. The head is spear-shaped and bright green.
Range: All over Thailand. The species ranges from India to China and throughout Southeast Asia.
Habitat: During the day you can find these snakes in trees and bushes usually. Occasionally they will be at ground level hunting frogs and small lizards. I have seen these snakes in all kinds of habitat, but usually in trees and leafy bushes. At night these snakes sleep in the same environment.
Active Time? Diurnal – active during the daylight hours.
Food: Frogs, small birds, small lizards.
Defensive Behavior: The oriental whip snake can spread its neck area to increase by double in size as a defensive technique designed to scare attackers. It is quite beautiful when either solid green or with the green, white and black checkered pattern displayed in full defensive posture. Sort of comical is what the snake does with its tongue when molested. It sticks the tongue out and holds it there for some seconds, or minutes.
Venom Toxicity: Weak. Although this is considered to be a rear-fanged and venomous snake it is not very dangerous to humans due to its non-aggressive nature and weak venom characteristics. The venom would need to be injected into the wound with time – with a chewing motion. Not many people bitten are going to let a snake hang off them for any amount of time. Some do, and they may have severe complications and require hospitalization.
Offspring: In Thailand, the Ahaetulla prasina can mate during either of two times. Usually between April and July, and then also between December and January. Gestation period: ~ 6 months. Number of births: 4-10. Lengths at birth of offspring: 400 – 500 mm.
Notes: These are wonderful little snakes to catch and let go. These snakes do not do well in captivity and many die within days of being kept in an enclosure. They are as beautiful as snakes get, but please resist the urge to capture one to keep as they are very sensitive and die easily.
We have not been bitten by these snakes, but in the wild when catching them they will attempt to strike at times. They are fast and have a short striking range. What is really amazing about these snakes is the way they effortlessly glide down a hill or through trees like on ice. They can climb extremely fast and disappear before you have a chance to grab them. See the video below!
These snakes are not often confused with other snakes here in Thailand because they are quite distinctive. Their head is long and to a fine point. They are very thin at the neck before the head unless they have flared up in defense.
Also known as mangrove viper, shore pit viper, Gray’s pit viper, purple-spotted pit viper, and shore pit viper. In the past (2004-2011) this snake was called Cryptelytrops purpureomaculatus.
Thais Say: Ngoo pang ka
Length: Males grow to about 60 cm and females to 90 cm on average.
Habitat: Usually near water and very wet areas like mangroves along the ocean or brackish water. However, recently one was found on a sidewalk by a bungalow on the island of Koh Phi Phi in Krabi province, Thailand. They like stream banks with good cover – low lying plants that they can hide under. They also may like hilly habitat and have been found as high as 2,000 meters elevation in bamboo jungles. These snakes are found in high numbers on islands around Thailand. I have found this species in some abundance along the shore in mangroves in Krabi province.
Behavior: Diurnal and arboreal. These snakes are very easily agitated, and once they get going they are slow to calm down. Their strikes are very fast, but have a short reach. These are known by snake handlers to have a “bad temper.”
These Thailand pit vipers can have many color variations. They are usually like the photo above – greyish with a bit of purple in the coloring. Some are very purple. We’ve also seen a brownish toned mangrove pit viper with some yellow highlights. Now for our top photo we have a greenish toned viper. Obviously – color is highly variable in this species. Tom Charlton found black variations on Langkawi Island in Malaysia, and John Paul Foenander has also found dark, even black, specimens in Singapore.
Venom toxicity: Venomous and very toxic to humans. Though people have died as a result of bites from this snake, this is not usually the case. Symptoms – pain, severe swelling, bruising, blistering, and necrosis are more likely.
Here (it isn’t live any longer) is a study of treating a bite by this snake with T. albolabris antivenom from the Queen Saovabha Memorial Institute with some success.
Treatment: Antivenin is indicated.

Size – Average length around 70 cm. Maximum about 120 centimeters. The young are very thin – like a pencil. The adults are thick – like a forearm or even a human leg.
Description – Triangular head distinct from neck. Color varies quite a bit. Brown with incomplete orange bands on the dorsum and laterals, or brown with beige bands, or black with grey bands. Many variations. Sometimes the snake appears quite orange.
Range – All over Thailand and almost always beside or in water: Pools, streams, rivers, puddles, lakes. They are not found on hills or mountains.
Food – Prey includes fish, frogs, and tadpoles primarily.
Behavior – The water snake Homalopsis buccata lives in fresh and salty mixed with fresh – brackish water. These snakes live in and near any body of water – natural or man-made. Puff-Faced Watersnakes are found almost always in the water or on the bank. Small holes in the bank are often home for these snakes. This snake is primarily active at night, but I have found a few during the daytime.
Young – Born alive without eggs. Coloration – orange and black bands.
Danger – I’ve found dozens of these snakes and they are typically strong and active biters. They can strike like a viper – backward and vertically. I’ve been bitten in the finger by a 70 cm. long snake when I was 5 inches away from the head, coming from behind to grab the neck. With the bright headlamp in his eyes, I don’t know how he could have possibly seen my hand coming. It wasn’t a glancing strike, he bit and held on for a couple of minutes. I have heard others say these snakes don’t tend to bite. Maybe they are talking about in their experiences in the pet-trade.

Here is a whip snake that was a bit of a mystery for a while, my first one was finally identified by an American expat snake researcher in Bangkok – Michael Cota in 2007.
This snake is found in Southern Thailand. We’ve found some in Krabi province of Thailand. There were a couple found in the southernmost provinces – near Narathiwat – near the Malaysian border.
Dryophiops rubescens (Keel-bellied Whip Snake)
Also known as: Red Whip Snake, Brown Whip Snake, Keel bellied whip snake, keel bellied vine snake.
Length: As long as 1 meter (3+ feet)
Description: The head of this snake is browner than any other part of the body. Keep in mind there are red and brown varieties. The head is elongated and has a ridge between the eye and snout. Pupils are set horizontally. The body of the snake is slender – ideal for climbing through vines and light growth.
The snake is measured in grams, not exceeding 300 grams for the largest of them. Scales on top of the body are smooth. The underside scales are keeled and are excellent for climbing. The whip snake I caught yesterday was able to climb up a smooth plastic water jug and grip it tightly. I was quite surprised. The head is brown, the neck and the first half of the body is silver/grey and mottled with some black and dark grey. The belly is pale yellow under the head and neck, and toward the tail gets a coloration very similar to the top – heavily mottled and darker brown moving posteriorly. These snakes are thinner than my smallest finger.
Range: Literature has this snake occurring only in Thailand’s deep south, but we have found half-a-dozen in various spots around Krabi province – so, obviously the range includes this province, probably as well as others.
Habitat: Trees and ground. I found a few on the ground and some in the trees. They are excellent climbers and love vines and light brush. I’ve also found them twice on 60 cm diameter trees, climbing slowly. Recently we found one hanging out in the curve of a guardrail on a mountain in Krabi.
Active Time? Diurnal, but possibly also nocturnal – they’ve been found on trees at night and appear to be hunting. Most of our finds were during daylight hours.
Food: Small geckos and frogs primarily. Possibly small insects.
Defensive Behavior: Accurate strikers! One of the ones we’ve had didn’t bite at all. One got me in the head twice before I even knew it struck. Another tagged my finger, striking quickly and very accurately. I bled slightly. No ill effects were noted.
Venom Toxicity: Weak for humans. Effective for geckos, lizards and frogs. These are rear-fanged colubrids and a prolonged bite could possibly cause swelling and pain at the bite site.
Offspring: Nothing known.
Notes: These are really beautiful snakes resembling the Ahaetulla prasina in body morphology and Gunther’s Whip Snake. Studied closely you’d be amazed at the pattern in the body of the snake. Both of ours were brown whip snakes (we are guessing – there are few photos in the lit), there are also red-colored species of this snake.

The Plumbeous Water Snake (AKA: Rice Paddy Snake) is a venomous snake, though it is not dangerous to humans.
[Page Updated: 28 November 2019]
Enhydris plumbea (Plumbeous Water Snake, and Rice Paddy Snake
Thais say: (ngoo bping)
Length: average length for these snakes is about 50cm (19 inches)
Range: The plumbeous water snake is found all over Thailand as well as nearly all of southeast Asia.
Habitat: Near or in water. Lakes, streams, rivers, puddles, marshes, any where water is.
Active Time? Diurnal – active in daylight mostly.
Food: Food is generally fish and frogs, though other opportunistic eating may take place.
Defensive Behavior: Typical s-shaped striking position. Not very mobile on land.
Venom Toxicity: Venomous. Not toxic enough venom to affect humans severely. No known cases of death due to bite from this species in the herpetological literature.
Notes: As you might have guessed, these snakes are most commonly found in the vast rice fields of Thailand. These are common snakes, we have found two of them recently – one in a small pond with many frogs. One at a resort with a stream and some shallow pools of water.
I was hoping this year was going to be THE YEAR I found a king cobra hatchling – at least one under a meter. Alex Gillard made it happen for me, I didn’t get to find it, but we were at the same place and I’d actually just passed the place he found the little king – about 30 minutes before. Good enough for me, I just wanted to see one in the wild and get some photos and videos.
This has been my target species for about ten years now. I’ve found some adults, and one adult even found me, but I have never seen a king cobra in the wild less than three meters in length.
Juvenile king cobras are very difficult to find. People say they’re ‘smart’ – and yeah, I guess they are. I’ve never even heard of someone finding a hatchling king in the wild. One time a doctor from Malaysia sent me a photo of a tiny hatchling outside his clinic – in the middle of the day. It had probably just hatched.
Certainly, nobody goes looking for and finds king neonates.
Until Alex found one.
So, anyway. My life is complete. Enjoy the photos of this stunning little one-month old king cobra found in Krabi. I don’t know how many times I’ve been herping over the last ten years, certainly well over 1,000 times. And still, I’ve never found one myself!
KING COBRA (Ophiophagus hannah – Thailand King Cobra)
In Greek, ‘snake eater.’ Sometimes called ‘Hamadryad.’ Discovered and described by Danish naturalist, Theodore Edward Cantor in 1836. The species name, hannah reflects the snake’s arboreal habits, from Greek mythology it refers to tree dwelling nymphs of the same name.
Ophiophagus hannah occupies its own genus, Ophiophagus. This is different from other cobras in the Naja genus which have multiple species within the genus. There has been talk about breaking up the genus into a number of species, as differences exist in coloration, scalation, and in comparison, king cobras can be easily distinguished by the shape and size of the neck hood. Kings have a longer, thinner hood. Other cobras grow to maximum length around two meters in length – much smaller than king cobras. The king cobra has chevrons lighter in color than the body color, on the neck and body that may be very pronounced, as in kings from China, or muted, as we see on melanistic king cobras here in Southern Thailand. A technical difference between Ophiophagus hannah and all other cobras is the existence of a pair of scales on the top and rear of the head called, ‘occipital scales.’ They are located adjacent to each other behind the usual 9-scale arrangement typical of colubrids and elapids.

In Thai language, it sounds like Ngoo how chang (literally “snake cobra elephant”, or ngoo chong ahng. There are many names for this snake.
AVERAGE AND MAXIMUM LENGTH
Max length about 5.85 meters. The presenter at the Queen Saovabha Memorial Snake Institute in Bangkok said the largest king was caught in Nakhon Si Thammarat in Thailand’s south, near Surat Thani province and it was 19 feet 2 inches in length.
All over Thailand and most of Southeast Asia.
I’ve seen a few king cobras (hamadryad) in the wild. One I saw in a park in Krabi – just the tail as it crossed the road behind me. I’m guessing it was an eight meter long snake. I know it is probably impossible, but I’m not joking. The tail was absolutely massive, longer and thicker by nearly double that of other 5-meter kings I’ve seen many of. This was quite possibly the biggest King Cobra in the world.
Another king I saw on the island of Penang, in Malaysia. I was coming down a very steep hill and I saw this 3-4 meter king cruising through the dense underbrush. It was absolutely awesome to see it there when there were so many people climbing the hill close by.
Another time I saw a king about one-hundred twenty meters in elevation up a limestone mountain in Krabi province. This one rested on the steps of a popular temple – Wat Tham Seua and I had to move it away so people could come down the steps. A large four-meter long king that was very fast! Note to self – don’t try to move a king that is higher than you are (it was on steps up ahead of me and was very fast to come down to attempt to strike at me because it had the height advantage.
Recently Tom Charlton and I found a 3-meter king cobra in Krabi and got some great shots and video of it. Facebook photo of it here.
Kings are all over Thailand and can be found near houses, or really – just about anywhere. But they are not found often. 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. One study done by the Queen Saovabha Memorial Institute in Bangkok showed that king venom is actually more toxic the younger the snake is.
KING COBRA HABITAT
Kings 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.
Another interesting bit of information is that the king cobra is said to be able to see as far as 100 meters during daylight.
The snake is mainly diurnal – found active during the daytime, but can also be active also at night.
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.
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 not to be taken lightly. I know a man personally, his brother was bitten on the upper arm/shoulder and died in less than 10 minutes on the way to hospital.
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 (and have) killed elephants with a good bite. More information on venom constituents and treatment for king cobra snakebite here.
O. HANNAH ANTIVENOM
There is a specific antivenin for the king cobras manufactured by the Red Cross Queen Saovabha Memorial Institute in Bangkok, Thailand and available online for about $110 (May, 2015) for enough antivenin to counteract .8ml of king cobra venom. If the hospital you’re in does not have it in stock and cannot order it quickly from another nearby source, there is an alternative. Tiger snake antivenin can also work well. Online: Snake-Antivenin.com (no affiliation).
Ophiophagus hannah is the only snake known in the world that creates a nest (usually of bamboo and other leaves). This snake lays eggs which they stay with in the nest until ready to hatch. When the eggs begin hatching, the female king 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 dendrophila).
Young king cobras spend their early months, and possibly years in the trees. However, recently (Spring 2016) I have found two hatchling king cobras dead on the road in Krabi. Did they attempt to cross the road immediately after hatching while in search of a proper tree to climb? Not sure. Would love to find out. If you have any insight – do let me know!
From Luke Yeomans: “A female usually deposits 20 to 40 eggs into the mound, which acts as an incubator. She stays with the eggs and guards the mound tenaciously, rearing up into a threat display if any large animal gets too close, for roughly 60 to 90 days. Inside the mound, the eggs are incubated at a steady 28 °C (82 °F). When the eggs start to hatch, instinct causes the female to leave the nest and find prey to eat so she does not eat her young. The baby king cobras, with an average length of 45 to 55 cm (18 to 22 in), have venom which 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 IUCN Red List publishes information about the conservation status of reptiles across the globe. Here is what they had to say about King Cobras:
Ophiophagus hannah has been assessed as Vulnerable. This species has a wide distribution range, however, it is not common in any area in which it occurs (with the apparent exception of Thailand, and there only in forested areas), is very rare in much of its range, and has experienced local population declines of over 80% over 10 years in parts of its range. Pressure on this species from both habitat loss and exploitation are high throughout this snake’s range, and while no quantitative population data is available, it can be conservatively estimated that the population size has declined globally by at least 30% over an estimated three-generation period of 15-18 years. More detailed population monitoring in the more poorly-known parts of this snake’s range may reveal that this is a conservative estimate.
I mentioned earlier having seen many dozens of king cobras run through the snake show here in our local area. That is just one King Cobra Show out of perhaps a dozen in the country. If every show caught and disposed of 50 king cobras annually, that’s 600 adult king cobras yearly that are being depleted from the forests just here in Thailand. Kings mate once per year and their eggs are highly vulnerable to predators like monitors, other snakes, rats, and weather phenomena like high humidity and monsoon rains. Kings lay eggs just before the rains start.
My best guess is that king cobras are disappearing from the wild at a frightening rate. We only mentioned snake shows here, but what about all the king cobras that are found and killed across southeast Asia for food, or out of fear? There must be hundreds more, perhaps thousands per year more that are killed by people that come across them.
I hope the IUCN Red List updates their listing for Ophiophagus hannah and assigns a label more serious than “Vulnerable.” Something drastic is needed to save the country of Thailand’s wild king cobras before they disappear like they did in Penang, Malaysia.
Species: O. hannah
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. Even better to interact with it. Gotta love Thailand!
This page is focused on King Cobra (Ophiophagus hannah) snakes because their demise is imminent here in Thailand, and already in most countries they are not found in near the numbers they once were. On the island of Penang in Malaysia, it is said that kings can only be found very occasionally on the mountain. They used to be common. I was lucky enough to see one there on a very steep section of the hill while descending. It was three to four meters long and much thicker than my forearm. It was in the underbrush, moving slowly, perhaps thinking it was unobserved. That was two years ago, and maybe that snake has been a meal for someone by now. It’s entirely possible.
In Thailand I’ve watched just one snake show take over fifty king cobras each year out of the wild. They ‘rescue’ them from homes, yards, businesses, gardens, and farms. The kings spend a couple weeks or months rubbing their faces raw and bleeding against the fence trying desperately to escape. Some of them are put in the king cobra show – where they are teased mercilessly three to ten times each day for tourists that are interested in seeing snakes, but don’t really understand the state of the kings that are held there.
I cannot imagine that king cobras as a species have more than another few years of existence in Thailand, Malaysia, Philippines, Laos, Singapore, and Taiwan. The IUCN Red List site lists king cobras as ‘Vulnerable.” Kings are being collected and sold in great numbers to buyers in Bangkok who cook them up as a meal, or send them on to China for the same purpose.
It wasn’t long ago that the Queen Saovabha Snake Farm – “The Red Cross Snake Farm” in Bangkok was ‘broken into’ and something like seventy king cobras were ‘stolen.’ Hmm, wonder where they went. Seventy king cobras had to fetch a nice price, I’d think. Tens of thousands of US Dollars – easy. Not accusing, it’s just a very sad state of reality for these and other snakes poached for their skin, blood, bile ducts, tongues, and meat.
So this page will be a collection of all the best information I can source about my favorite species of snake, King Cobra – Ophiophagus hannah.

Update 7/20/2016 – I’ve seen a number of king cobras in the wild now over the years. Four of them have been hundreds of meters high on mountains. Many snake enthusiasts want to come to Thailand to see king cobras, and I have to tell them… the chance of seeing one is slight. I’ve lived in Thailand for ten years and I’ve seen only a handful, and I’m in the rainforest often. Your best bet is to come to the country and stay for a couple of months. Stay at PhanomBenchaMountainResort.com in a bungalow, and hike during the days around there. That’s my best advice. Your chance at seeing a king cobra is not high – you would probably need weeks of walking around during the day to see one. It’s all luck!
Thais are a bit crazy about cobras – it is the most easily recognized snake, and though I have met few people that can identify other snakes, most know what a cobra looks like. There are even amulet necklaces of cobras!
