Thailand Venomous Snake Photos

[Page Updated: 14 July 2023]


King Cobra (Ophiophagus hannah)

This is the longest venomous snake on the planet, and they get to around 6 meters long (19 feet!). The King Cobra length isn’t the scary part, it’s the amount of venom they can inject with one bite – which can kill an elephant. The brother of a friend I have was killed by a bite to the chest while doing a snake show with a king cobra. He died in less than 10 minutes. Kings are rather slow to bite, but if you are within striking distance, and they think you are a threat, they might feel threatened enough to strike.

Monocled Cobras (Naja kaouthia)

These are usually quite dark brown, black, or dark grey snakes that are very fast strikers and movers. The Monocled Cobra’s venom is much more lethal than the King Cobra’s venom, so only a very small amount is needed to cause death in humans.

I met a woman who lost a husband recently, due to a bite on the man’s toe when it came out from under an outdoor refrigerator as he opened it to get a beer. The venom is both necrotic and neurotoxic. First, the man who was bitten lost his foot to necrosis. Then up to his knee. Then his entire leg and the doctor assured him and his family – he would be fine now.

He died days later. Monocled cobras are quicker to bite than king cobras and are exceptionally dangerous. Do not mess with this snake.

Naja kaouthia just might be my favorite snake… Monocled Cobra.


Banded Kraits (Bungarus fasciatus)

Banded Kraits are yellow and black snakes that are active at night. During the day they are usually quite docile. Some are foolish enough to handhold them during the daylight hours. Show this snake more respect, its venom is quite lethal and kills people each year in Thailand and other countries in Southeast Asia.

Bands can be yellow and black, white and black, or even with longitudinal (yellow and black striped) instead of banding due to genetic anomaly.

Malayan Kraits (Blue Krait) (Bungarus candidus)

Stronger venom than the Banded Krait, but not as lethal as it’s sister – the Multi-banded Krait, that looks very similar. Malayan Kraits are generally not interested in biting, but they have one of the most toxic venoms of any snake. Extreme caution is recommended.

Red-headed Kraits (Bungarus flaviceps)

The Red-headed Krait, is seen as often during the day as at night. These ultra-lethal venomous snakes are quite rare to find at all. I have seen just two in more than a decade of looking for snakes in Thailand. Most people never see one in the wild. Their venom and behavior has not been well-studied but their venom is very toxic, like the other kraits.

Many-banded Kraits (Bungarus multicinctus)

A small, less than 10-inch snake called Bungarus multicinctus killed famous American herpetologist, Joe Slowinski while he was on an expedition in Burma and far from a hospital with respirators. He died within 30 hours from the Many-banded Krait bite. These snakes have venom which is in the top 5 of the most lethal territorial snakes in the world. These snakes look very similar to the Malayan Krait, but they have more bands.

Malayan Pit Vipers (Calloselasma rhodostoma)

These snakes have the distinction of killing the most people across Thailand of any other snake. Malayan Pit Vipers have large heads, very large fangs, and a strong bite that can inflict deep wounds filled with venom. These snakes love the grass and light cover. They tend not to move at all when approached, and don’t give any noise before striking. Usually people die when they don’t get hospital treatment quickly. The venom is primarily hemotoxic and the victim bleeds from orifices on the body – as well as from the brain.

Siamese Viper (Daboia siamensis)

Found north, west and east of Bangkok – this snake is not to be found in southern Thailand. Siamese Vipers kill more people across the globe than any other. Like the Malayan pit viper these vipers are very strong, thick, and have large fangs.

Brown-spotted Pit Viper (Trimeresurus venustus)

And she is a beautiful snake too! In the header of this website is a photo of what I think is the first venomous snake I saw in Thailand – the Trimeresurus venustus, the Beautiful Pit Viper. These are small vipers with very small scales – especially on the head. They are not so deadly, but you will have strong local reaction to the venom.

The image I use in my header at the top of this page is also the T. venustus – Beautiful pit viper.

Kanburi Pit Viper (Trimeresurus kanburiensis)

Very rare and found only in and next to the Kanburi province of Thailand. Very similar in appearance to the beautiful viper.

Wagler’s Pit Viper (Tropidolaemus wagleri)

Wagler’s Pit Vipers are common in Phuket, and called by some, “The Temple Viper.” These are incredibly stunning snakes to look at. Their patterns are diverse. The photo above is a female. The male is about 1/4 the thickness, with a green overall color and red/white spots.

Indo-Malayan Mountain Pit Viper

A father sent me photos of a snake that his young son was kicking at while they visited a waterfall on the Thai-Burma border in Phang Nga province. These are rare in Thailand, and have a nasty bite. Luckily, his son was not harmed.

Mangrove Pit Viper (Trimeresurus purpureomaculatus)

These are pretty elusive. They spend time in mangrove areas near the ocean, and I’ve yet to see one in the wild. They are big biters and not docile at all. Be careful if you come across one of these small vipers. Mangrove Pit Vipers are beautiful – but dangerous.

Large-eyed Green Pit Viper (Trimerusurus macrops)

As the name implies, the eyes are large on this green pit viper. Green pit vipers in Thailand are quite difficult to tell apart from each other. Be careful with all of them.

  1. Very interesting and useful when I am working in the garden in Ban Phe, Thailand.

    1. Hi

      My friend and I recently had an encounter with a small snake on a rocky beach on Koh Kradan. We took pictures of it but none of the locals could tell us what kind it was and so far we’ve had no luck googleing it . Will you help us put a name to it, if I e-mail you some pictures of it? It kind of sneaked up behind us and gave us a scare. It didn’t mind us at all and it actually crawled across my sunbathing mat. It seemed calm and well tempered :)

  2. I have seen all these snakes.i live in the mid of rayong and ban phe.

  3. Seen a few snakes in Thailand south Rayong and Trang near Phuket a weird small fat snake with bands and a fat little head that was slowly off to a near pond and a black yellow thing in a tree next to a river we were rafting near Krabi / Phuket a couple of green whip snakes like to wrap themselves round the door handles. Small cobra came into the school and was killed by the dinner ladies and a red-headed thing try to eat a frog which i rescued (strange cause it hopped off seemingly unharmed plenty of sea snakes esp washed up after tsunami in Phuket. Rayong area is lovely wild and very wet and also has rose quartz as well as moonstones and i expect some good quartz crystals etc as wellas gold mines etc

    1. You mean Ranong (Rayong is on the east coast of the Gulf of Thailand).

  4. Hello
    You have a very informed site , it may save lives, I live on the Nam Ping river 24 km North of Chiang Mai, I am from Australia , where I have been in contact with Taipan’s Fierce Snakes, in the Desert Also king Brown’s (very aggressive when cornered)
    so I am no stranger to seeing snakes,
    My 2 siamese cats are forever bringing Me snakes, they are long and thin I guess some sort of tree snake , I save them when I can,
    The other day a dead snake in yard was verity similar in color to the viper light brown and slightly darker bands, without the broad head, it was decomposed so I didn’t bother with a pic,
    What if any snakes in this region would be dangerous,
    Regards Mark

    1. Hi Mark,

      Yep, you’ve got your share of venomous and quite deadly snakes in Australia. Up north there are cobras including the king cobra. There are kraits – Malayan krait, and possibly the many-banded krait – the most potent venom of any snake found in Thailand. There are a number of vipers, and maybe including the Mountain Viper. I don’t know if the corals snakes are up there that far, but I wouldn’t doubt it. I don’t have a geographical break down specifying which snakes are found where. Would be nice, but on the other hand, so many snakes are found outside the range that it probably doesn’t make sense to even put the time into that sort of thing. Assume all Thailand snakes are to be found in your region. Send pics when you get them…. Cheers man!

      1. Hey I found this snake in a log in my apartment and was wondering what it is if you email me I’ll give you a picture of it i don’t know how to post pictures here.

  5. My name is Owen Brindle,
    I live here in Kanchanaburi Thailand with my wife Nong, this morning I went into the front garden to feed the fish and came across a 5 foot shinny black snake. When it saw me it took off. I called out to my wife Nong but by the time she got here the snake had disappeared. QUESTION… IS A SHINNY BLACK SNAKE 5 FOOT LONG POISONOUS…???

    1. Question – are you going to eat it? Poisonous means you’re going to suffer ill effects from eating it. Venomous means it can kill you with envenomation – biting and injecting venom.

      It could be venomous – yes. Could be a cobra. Do be careful. Sorry, you gave me little to go on. There are many snakes that fit that description.

    2. My wife and her friend killed a snake in our yard this morning, it was a metre long, black or dark brown with what apeared to be some mottling on its skin. I know it was a cobra because I saw its hood (only the front) yesterday when our dogs cornered it but what kind I do not know. We live near Uttaradit. Any ideas?

      1. Maybe the spitting cobra (Naja siamensis) or monocled cobra (Naja kaouthia).

  6. Informative website. I’m planning a trip to Thailand to train at a Muay Thai camp, possibly Fairtex. Is this snake issue something I should be overly concerned about or conscientious of?

    1. Nope. Unless you’re sleeping outside, on the porch on the ground, or anywhere snakes could find you at night. Also, don’t walk around at night without a flashlight/torch. Have fun…

  7. Vern,
    I think I have a baby Malayan Kraits. I am in Chiang Mai, Thailand and no one here seems to know what it is. If you would like a photo of it, just tell me where to send it. I don’t want to kill it, but I don’t know how dangerous it is.

    1. Please send me a photo, I think I may have seen one yesterday at a waterfall just out of Khao Lak, although only small it was not scared of us.

  8. When I was living in Krasang (About 20 Kilometers West of Surin) I had a Snake coiled up on the edge of my field, it was about 1 1/2 feet long (maybe less) with an dark emerald green back and a yellow belly. It had no fangs but sharp teeth that bit into my leather glove and to be honest, it probably would have let go if it’s teeth weren’t hung up in the leather. I cannot find any pictures that looked like it. Would you have any idea as to the name?

  9. I live in Chiang Mai, Thailand, and a couple nights ago, I killed a small (10 to 12 inches) snake. It was black with thin yellow bands, and a white underbelly. The only thing I can find online that looks anything like it is the banded krait, but the yellow stripes on that are too thick. Do you have any suggestions what it could have been?

  10. Hi , Just trying to identify a snake I nearly stepped on in my garden in Koh SAMUI, it was probably about 3 quarters of a metre long with a girth of about a hotdog, muddy Brown in colour with almost like black hexagons or broken black circular lines on it’s back, very quiet and non aggressive. Cheers

    1. I think you wrote me on the facebook forum already – and it was Ptyas korros – the Indo-Chinese rat snake. Is that right?

  11. Great info on venomous snakes. Currenty in south Thailand living on a rice farm about 70km south of Nakhon si thammatat. Went to the toilet this morning and found the back side of a snake slithering down the pipe to go outside. Only saw the last 3ft of it. But the description is of a dark green with a what I can only describe ad beautiful pattern and vivid pattern on it’s skin. Please get back to me as to what you believe it to be as I haven’t found anything that looks like it. Thanks mate !

    1. Hey Ozzzie,

      Hmm.. How thick was the snake? There are a couple with a nice pattern. Gonyosoma oxycephalum, Chrysopelea ornata, Ahaetulla prasina…

  12. My Wife I stayed in a luxury hotel in Thailand. The rooms were like shack cottages on the outside but 5* inside – right on the beach and over a lake – lovely. We returned to our room one night and a snake about 0.7m long and perhaps 25-35 mm dia was on the floor it reared round and headed straight at us with some speed. we left the room sharpish and shut the door and called housekeeping. They came down and I went in the room with them, then when I said it was jet black one guy jumped on the bed and the other legged it (they were barefoot to be fair) they wouldn’t let us stay in the room and we had to move. 5 days later we returned to our new room about midnight and when passing the original room a family of Swedish people had been evacuated from the room, it was midnight and they were waiting outside, they had escaped after being chased by a snake in the room. Any ideas? jet black, shortish skinny snake, fearless and had the Hotel staff paying lots of respect to?

  13. I just moved to Pai. I own Pai Adventures which is a white water afting and jungle trekking outfitters. What snakes to I have to worry about in Mae Hong Son province?

  14. Hey I am thinking about going to University in Thailand, I feel like i may rent an average place and i have heard they go in houses often doesn’t matter if your not on the bottom floor they can come up trees to the windows or even get into plumbing and strike while your on the toilet. Seems scary and i don’t like snakes. I know you said don’t sleep outside and walk with a flashlight but do u think if i have a cat and or dog i can feel 100% safe living in thailand? What do you do check your toilet and shoes every time, have a pet? How can you be safe for sure?

    1. I check my shoes for scorpions and centipedes. I think you will never see a snake in your plumbing. One person out of millions sees this phenomenon. I think don’t worry about anything…

      1. hey Vern,are you a snake expert?,i read that you said in one thread that sleeping outside on the
        ground in a place like Thailand is not safe,that the snakes will find you,others say that snakes
        will avoid you because they know you are to big for them to be thier prey,whats the real scoop on
        this,iam a backpacker that wants to back pack in the rural tropics and i like sleeping outside on the ground,never been to the tropics,but i know that thier are alot of venomous snakes give me a reply
        at…my name is Glenn….thanks

  15. Found this thin long snake on my drive in Na Jomtien. My husband said he saw our cat jumping up and over a hedge bush in or garden then obviously tried to lay with it. Maybe just a baby snake green and yellow striped with black square markings – any idea what it is and is it venomous?

  16. We had a very thin long( 3 meters) green snake (mottled) with a brown tail in our garden. My Thai wife says it is venomous but my info says it is mildly venomous and cannot kill you. We gave it plenty of space. We believe it is coming for small birds’ eggs. Can you identify it ?

    1. Hi Greg, I don’t know of a 3 meter long snake with mottled green and a brown tail, unless you’re talking about a king cobra? How thick was the body?

  17. Hi Vern, I live near Pattaya and a snake came into the house whilst the wife and I were watching TV last night. It was very dark grey, no markings, large scales, pale grey on the underside, 60-70cm long, 2cm in diameter, short taper to the tail. The head had a bit of a triangular shape and was not slim like the indo-chinese rat snake which I have seen, nor did it have large eyes. It moved slowly with a very wide S shape and was non aggressive. It did not hiss. (It got itself stuck headfirst in the track of the patio doors). The wife went apoplectic when I tried to pull its tail to get it out, so I used a stick to shuffle it backwards until free. I flicked it into the garden. It seemed totally unphased. Any idea as to what it might have been?

  18. I love snakes i was born with snakes not kidding

  19. I live in Surin with my wife, daughter & mother in law. My wife spotted a slender green snake with some red markings behind its mouth on top of the open window frame outside, when l got closer to have a better look it leaped off into the grass & disappeared. We thought it might be a green cat eye snake but not sure, any knowledge on this snake would be appreciated

  20. hi,
    we just had a black and white crait near our pig pens, i just shood it off, but did make me jump in the torch light
    great site by the way i use it all the time

    1. Yep, they are hard to miss – and yeah, can make you jump too. Where are you at – which province?

  21. Hi, we are going to visit Umphang in Tak province very near the Myanmar border and will be visiting jungle villages.
    Can you advise us on which snakes live in this area please .
    What other creatures may harm us may there be scorpions as well as mosquitos.
    Many thanks

    1. Mosquitos are by far the greatest threat. However, they have tigers and elephants, I believe. Snakes – cobras, pythons, vipers, kraits. Don’t walk at night without strong lights so you can watch every step. Stay alert… not sure what else to say.

  22. Iyellow snake with black dots maybe 80 cm long in the swimming pool roof garden in soi 28 sukhumvit central bkk. How she got up here is the mistery!

  23. are any of these snakes prone to be active in very hot weather during the mid day? I have been building ( clearing some trail for mtn bike usage) in Chaing rai area during the day, raking dead leaves down to dirt for a path and cutting bamboo shoots and chopping/hacking vines. Have been out the past four days in a secluded area, and seen ZERO snakes after moving hundreds of bamboo shoots on the ground and clearing a trail two to three feet wide completely down to dirt for more than 800 meters. I’m wearing some pretty thick boots with carhart/ type jeans. Got any suggestions on how to snakeproof myself more thoroughly or what specific snakes I can run into while raking thru the forest and moving bamboo? Perhaps I”m very stupid, just let me know. I can take constructive criticism.
    To me, it seems so hot that I question if they would be active or found under shallow leaves as its still so hot with less than two inches of leaves covering the forest floor. What do you think? Bill Email:

    1. Hi Bill, great comment – thanks for that. I know the monocled and spitting cobras are VERY active in the heat of the day. They ramp it up as they get hotter. In fact, I see monocled cobras here in Krabi at 3 pm. usually because it’s the hottest part of the day. Vipers are active at night, but sure, the Malayan Pit Viper could sit under some leaves in the heat. With boots – you’ll most likely be fine. The malayan pit vipers don’t strike above the knee – ever (from the ground). Cobras, you can usually see because they give notice – with the hooding and hissing. Cheers man – hope that helps.

  24. Dear sir – I stumbled on this page and struck by your kindness to answer each question. You seem very well educated and providing such a good service. I just wanted to say thank you for the interesting reading and what you’re doing for your readers.

    By the way, I live in Minneapolis, Minnesota and recently met a woman from Thailand. I am breaking up with her immediately. Ha ha.

  25. Hi
    We just found a 2-3 foot long, thin, leaf-green coloured snake on the top floor of our 4-story house in Bangkok
    Any idea what it might have been?
    We can only imagine it got in from the balcony, which it could have reached from the nearby trees but that’s only hypothesis
    Is there likely to be a nest nearby?
    The Rentokil guy who sprays for bugs found it & took it away he didn’t seem to know a lot about it, in fact he said he thought it was a toy when he first came across it.
    What’s the gestation period for most snakes?

    1. Snakes don’t have nests. Once eggs hatch, they disburse. Yes, could have come from tree. It’s likely either Chrysopelea ornata or Ahaetulla prasina. Both climb high and frequently come to homes for the geckos. Gestation period is usually 2 months, eggs are layed, then 2 more months. Cheers Paul…

  26. Hi, we are staying on Koh Phayam and yesterday we experienced the first bit of activity outside of the relaxing, slow paced life that dominates here.

    The commotion was caused by a 2.5 Metre! Long snake in a souveniour shop. It was grey in colour and it’s markings weren’t overly distinct. It’s belly was lighter in colour, and a bit white/yellowy/beige/dull green kind of colour. The locals were very very very cautious of it and a local man, with the right tools, managed to capture it.

    It’s head was relatively large,compared to the girth of its body, but from what little I know, pit vipers don’t grow that big. For a snake 2.5 metres in length its body was relatively thin, only about 2-2.5 inches across, max. There was no hood from what I saw, so King Cobra seems out. It moved extremely quickly, and I mean really fast, but it then stopped and wrapped itself around a manaquin’s leg and reared its head up about a a foot and a half off the ground whilst smelling the air vigorously with its tongue.

    My intrigue was great but my instinct was to not get too close and let the professional handle it. I’ve looked at several sites but nothing seems to match the description.

    The best I can come up with it a pit viper in colour but the length seems to long.

    Any ideas? Thanks Matt

  27. Vern,

    My 3 year old son lives with his mother in Sawang Daen Din, 90km South of Udon Thani. He was playing in the yard near our fish pond last night when he suffered a strike from an unknown snake on his lower leg (maybe 10-12 cm from the base of his foot on his calf). Fang marks are approximately 2.5-3 cm wide. He was complaining of leg and foot pain and after his mother noticed the fang marks rushed him to hospital. Thankfully it was a dry strike. My son could only say that the snake was black; as he is only 3 so not the most reliable witness. With the very vague description provided and given the region in Thailand any thoughts as to the species responsible?

    1. Last night what time? Can you send me a photo of the bite area? Any stomach upset, dizziness, eyelids closing????

  28. I found a small (but long) snake in my bathroom that is black with small green (maybe yellowish) markings on it, not really in any pattern, with a lighter underside. We get small scorpions in our bathroom too, and I’ve heard of some snakes that prey on the scorpions. I don’t have a photo, nor could I find one searching the internet. Do you know what this snake could be? Venomous? I’m mainly concerned to know for letting my daughter use the toilet by herself or not. Thanks.

  29. Fantastic site. Thank you.
    I used to live on Koh Lanta and we once ‘caught’ a King Cobra snake that was almost 6 meters long. I say we, I mean we called a professional who came to help us catch it.. It’s scales were as big as guitar picks.. Scary stuff! But the snake didn’t really want to attack us, even though my husband and friends tried to get it out of our recycling bin, they quickly gave up though when they saw how big it was!!!

  30. thank you
    i just saw the most gorgious snake thin grey with a red brown neck and a light green head 70 cm
    any idea? bye
    in Loei mountains

  31. We found a tiny snake in our apartment yesterday. It’s short and very thin with green and black stripes. Do you know what kind of snake it is and if it’s dangerous?

    1. Hard to say without a photo. The only green/black snake I can come up with with “stripes” is one of the rare rat snakes just recently found in Chiang Mai and far north.

      The golden tree snake has what appear to be bands, or checkered black and greenish. It’s harmless. Is this the snake – Golden Tree Snake ?

  32. HI Vern. Thank you for doing what you do. It’s been a very long time since I’ve lived in Thailand – about 25 years. I lived in Phattalung province, about halfway between Phattalung city and Hat Yai. I stumbled upon what very much looks like a red-headed krait from your picture. It was little, pencil thin and maybe 18 inches or 2 feet long. It was all black or dark grey (if I remember correctly) but when I examined it more closely it puffed up defensively and exposed a bright red head. I’ve never heard of a red headed krait or any other snake doing this. Did I imagine it, or do you have any idea what it was? Thank, Corey.

    1. Hi Corey, first off – thanks! The snake is an unknown. I’d say Red-necked keelback because in the south, they are the only snake with a red head (red neck) that is capable of ‘puffing up.’ But, they aren’t generally described as black or grey. When in need of a shed, they can have muted colors and appear somewhat grey I guess.

      The red-headed krait has black/grey body and red head and red tail. So does the Blue Long-glanded Coral Snake. Neither puffs up the head or neck.

      There is another red-headed snake, a fossorial species, Calamaria schlegeli that has a red head and grey body. These snakes reach 45 cm in length (1.6ft?). That’s a possibility. I don’t think it puffs up the neck.

      Macrophistodon flaviceps has a grey body with light banding, and a red head. It’s a keelback. It might be able to do something with the neck to flare. So, that is a possibility. They get around 2 feet maximum length.

      Actually, I’d guess it was this one. I’ve never known anyone in Thailand to find one though!


  33. Hello, I was visiting Phuket in early January and during the middle of the morning looked out my rental and saw a very large black snake sticking off a bush. Probably about the length of my arm. It was shiny black and i could see every scale on its face from close to 20 or 30 feet away. I went to the window to fet a closer look and it turned around and i saw a yell9w under belly. All i can think after looking at numberous pictures is that it was a king cobra. Are there any other snakes in Phuket that fit this description?

    1. Monocled Cobra. Not sure what you mean that you could see every scale from 20-30 feet away. Is that even possible? Anyway, king cobras and monocled cobras have big scales and a yellow bottom in the front under the hood.
