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.

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.

Very dangerous and hard to identify. A very beautiful pit viper as the pictures show.

  1. 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 ?

  2. 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!


  3. 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.
