Thailand’s 3 Very Common Venomous Snakes

 (Last Updated: 8 May 2017)

Thailand has approximately 60 snake species that are considered venomous and potentially dangerous to human beings. Thirty of them are on land, and deadly. Below are photos, videos, and links to more information on some of the most common snakes that fit this description.

Calloselasma rhodostoma. Malayan Pit Viper. 

Very dangerous. Potentially deadly. This snake is active at night (nocturnal) and during dawn and dusk (crepuscular) and during rainy or very overcast weather. I have found them in the lowlands at sea level, and as high as 500 meters here in Thailand.

The following is a video showing the color variations for the Malayan pit viper. These are all from Southern Thailand, so depending where you are in the country, yours may look similar or slightly different. The very triangle head shape and triangle pattern on the top back will not change.

Naja kaouthia. Monocled Cobra.

Very dangerous and potentially deadly. This snake is most active during the daytime, but is also sometimes found to be active at night. During some of the hottest days they can be seen regularly crossing the roads. Around 3 pm. seems to be a very active time for them.

Rhabdophis subminiatus. Red-necked Keelback.

This colorful snake was often kept as a pet and hand-held before it was realized they pack a deadly bite. Their venom is as strong as a banded krait on the LD scale. They are active during daylight hours and are commonly found across Thailand.

Keep in mind, the smaller the snake, generally the more quickly it can strike.

Banded Krait – Venomous – Deadly

Banded krait - Bungarus fasciatus, venomous and deadly snake in Thailand and many other countries in Southeast Asia.

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.

(Last updated: 8 May 2017)

Banded Krait Snake at Bangkok, Thailand Snake Farm
Yellow Banded Krait. Highly venomous, deadly, and relatively common in Thailand. There is a white and black version also called the Blue Krait. See page on right side. This photo is of a man at the Red Cross Snake Farm in Bangkok.

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.

Range: All over Thailand and most of Asia

Notes: I have yet to see a live banded krait in the wild, except 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 2015- 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 blood stream 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.

Red Headed Krait – Bungarus flaviceps – Deadly

Deadly and Beautiful, the red-headed krait is one of the rare and very venomous elapids living in Thailand's rainforests. This is a closeup photo at 3 a.m. as we found one in Trang, Thailand.

(Last updated: 20 February 2017)

Red Headed Krait (Bungarus flaviceps)

Thais say: Ngoo sam lee-um hoo-uh si dang

Length: These kraits grow to about 2 meters long, though most adults found are shorter.

Appearance: Somewhat pronounced vertebral ridge, which differentiates from the Malayan Blue Coral Snake (Calliophis bivurgata). Body is black or dark grey, the head and tail are bright red or orange. The tail on the venter is also the same color. The rest of the venter is creme to white colored. The head is more distinct from the neck than C. bivirgata. Dorsal scale count: 13-13-13.

Range: In Thailand the Red-headed Krait is only found in the southern Thailand provinces from Ratchaburi and southward. Across the globe they are most heavily concentrated in Malaysia, Borneo, and a couple other places. Recently I found a large 1.9 meter specimen in rainforest in the Trang province. I have also found them in Surat Thani, and Krabi provinces.

Habitat: Lowlands and hilly rainforest type habitat. The last four of these snakes I saw were all found at less than 200 meters elevation.

Active Time? Probably active both at night and day. Three of four of these snakes in our local area were found during the daylight.

Food: Some say the red headed kraits eat more frogs, lizards, eggs, and rodents than other snakes. Probably they are opportunistic and eat whatever presents itself.

Defensive Behavior: Of the four snakes examined – none struck out, none attempted to bite at all. Note – all but one was handled during daylight hours.

Venom Toxicity: Venomous, and deadly. The venom has been shown to have an LD50 subcutaneous measurement of .35 mg/kg for Bungarus flaviceps, while Bungarus candidus (Malayan Krait) was .32 mg/kg, and Bungarus fasciatus (Banded Krait), .62 mg/kg and less than that in another study. This makes it one of the top venomous snakes on the planet and within the top three most venomous in Thailand. The black mamba is listed at the same .32 mg/kg by venom researcher, Dr. Bryan Grieg Fry at his site. (well, now he pulled down his chart). Only 10 other terrestrial snakes in the world were listed with more potent venom. Little is known of the this venom’s effect on humans after a bite, though it is likely very similar to a bite from Bungarus candidus, I could find no treatment studies due to bites being quite rare by this krait species.

From the abstract of a recent (2/2010) venom study in Malaysia: Bungarus flaviceps (red-headed krait) venom presents an intravenous LD50 of 0.32 μg/g and exhibits enzymatic activities similar to other Bungarus toxins. ELISA cross-reactions between anti-Bungarus flaviceps and a variety of elapid and viperid venoms were observed in the current study. Double-sandwich ELISA was highly specific, since anti- B. flaviceps serum did not cross-react with any tested venom, indicating that this assay can be used for species diagnosis in B. flaviceps bites. In the indirect ELISA, anti- B. flaviceps serum cross-reacted moderately with three different Bungarus venoms (9-18%) and Notechis scutatus venom, but minimally with other elapid and viperid toxins. The results indicated that B. flaviceps venom shares common epitopes with other Bungarus species as well as with N. scutatus. The lethality of the B. flaviceps venom was neutralized effectively by antiserum prepared against B. candidus and B. flaviceps toxins and a commercial bivalent elapid antivenom prepared against B. multicinctus and Naja naja atra venoms, but was not neutralized by commercial antivenoms prepared against Thai cobra, king cobra and banded krait. These data also suggested that the major lethal toxins of B. flaviceps venom are similar to those found in B. multicinctus and B. candidus venoms.

Treatment Summary: Envenomation can produce moderate to severe flaccid paralysis, and respiratory failure requiring intubation and ventilation in severe cases. Antivenom available for major species (detailed below), could potentially prevent worsening of paralysis, but may not reverse established paralysis.

Key Diagnostic Features: Minimal to mild local reaction + flaccid paralysis

Antivenom Code: SAsTRC04
Antivenom Name: Banded Krait Antivenin
Manufacturer: Science Division, Thai Red Cross Society
Phone: +66-2-252-0161 (up to 0164)
Address: Queen Saovabha Memorial Institute, 1871 Rama IV Road, Pathumwan, Bangkok 10330
Country: Thailand

Offspring: Two clutches from two adult female red-headed kraits were studied by Chulalongkorn University scientists in Bangkok. One clutch was four eggs, and the other, six eggs. After 81-84 days in incubation at 26-27C and the other clutch at 30-32C eggs hatched. Less eggs hatched at the higher temperature incubation. Average hatchling length was 28.9cm +/- .8cm measured from snout to vent. Weight of each was 7.2 to 7.8 grams. Humidity in the incubation enclosures was 60-70%. After 7-10 days all snakes had shed.

Notes: I have seen four of these kraits, and they are quite incredible to find in the wild considering how rare they are. Bungarus flaviceps has not been studied very well, and I suspect that most of the information on Wikipedia and other information sources has been generalized from other Thailand kraits like the Blue Krait (Bungarus candidus) and Many Banded Krait (Bungarus multicinctus) because the wording seems too similar to be by chance. There are a number of Malayan Blue Coral snakes mis-identified on Youtube videos, and on Wikipedia.

These snakes have not been studied well in captivity or in the wild, except for the previously mentioned study in which the kraits lived surprisingly long. Usually the literature shows the red-headed krait dies quickly in captivity. These kraits are not known to bite during daytime, but, be exceptionally careful when handling them.

Substrate: Best? Leaves and something large to hide under – wood is best, rocks, something solid.

Ways to differentiate Bungarus flaviceps from the Malayan Blue Coral Snake (Calliophis bivirgatus):

1. B. flaviceps has a triangle cross-section, while C. bivirgatus has more of a round cross-section.
2. C. bivirgatus has a venter that is all red – orange. B. flaviceps has red under the head and tail only.
3. B. flaviceps reaches about 2 meters while B. bivirgatus grows to just 1.7 meters.
4. B. bivirgatus has lateral lines on both sides of the body toward the venter, which are solid light blue or white.
5. By studying some video one can see how their crawling pattern differs.
6. B. flaviceps has a more sizable head, a wider head, and larger mouth than the coral snake.

7/25/13 Update. At 11:30 pm in a Thailand National Park in Trang Province, a friend and I found a large 1.9+ meter long Bungarus flaviceps on the trail and photographed and shot video of it. Video #1 is of this snake. The photos on this page are all of the same snake. As with all snakes found, it was released in the same spot as where it was found.

Small Spotted Coral Snake – Venomous – Dangerous

Speckled Coral Snake - Venomous - Potentially Dangerous
Speckled Coral Snake – Calliophis maculiceps

“Calliophis maculiceps” (Speckled coral snake, Small-spotted Coral Snake)

(Last updated: 26 July 2016)

Length: Average max length is 35 cm

Range: These small coral snakes are found all over Thailand and some other countries in Asia. I have seen a couple dozen of these snakes in southern Thailand, usually found by people in their potted plants outside.

Habitat: These snakes enjoy the leaf litter, loose dirt, and cool areas under rotting trees and other foliage. Occasionally they are seen dead on the road during or after rain when they probably come up above ground to avoid water. They are very rarely found during the daytime, and one scientist said they are usually only seen during September and October. But, I’ve seen them year round.

Active Time? Nocturnal – active almost exclusively at night, or underground during the daytime.

Food: Very small snakes like the Brahminy blind snake, worm snakes, worms, and probably termite, ant, and other insect eggs.

Defensive Behavior: They curl up their bright red (pink or orange), white and black spotted tail as a defense mechanism. These snakes have little else for defense, as they don’t usually attempt to bite. The mouth on the Calliophis maculiceps is very small, yet they are fully capable of biting and envenomating humans.

Venom Toxicity: This is a coral snake, so, the potential for life-threatening envenomation does potentially exist. Their venom is neurotoxic. There are places on the human body where this snake could get a good bite in, given the chance. Between the fingers and toes is an ideal piece of skin to bite. Just be very careful with these, and all coral snakes. Just because a snake has not been known to cause significant envenomation in the past, doesn’t mean it won’t happen. If you keep this snake as a pet – be very careful not to get too comfortable holding it – it is potentially a deadly snake.

Offspring: One scientist noted a clutch of just 2 eggs.

Notes: These are remarkably beautiful snakes, and yet so small that they could be mistaken for a worm of some sort if. Body patterns can differ slightly. Some, like this juvenile exhibit black stripes and spots. Some have just spots. Some are almost uniformly brown with very few or light spots. The body of this coral snake is round, without a pronounced vertebral ridge. The belly is bright orange, and the tip of the tail has white and black. When the tail is raised, it is quite stunning. These snakes are common, and are kept as pets across the world.

The Blue Malaysian Coral Snake is a venomous elapid and is one of the most strikingly beautiful snakes you’ll ever see. I’ve been lucky enough to see one crossing the road in southern Thailand and I didn’t have any snake hook to grab him.

(Last updated: 7 April 2017)

Calliophis bivirgata flaviceps (Blue Malaysian Coral Snake, Blue Long-glanded Coral Snake)

3 Sub-species: C. b. bivirgatus in Java – lacks blue stripes on ventral.
C. b. flaviceps in Thailand, Burma, Laos, Cambodia (possibly, no records), Peninsular Malaysia, Singapore, Sumatra and various islands of the Riau Archipelago. C. b. tetrataenia in Borneo has a light yellow stripe on side, without blue stripe.

Thais Say: ngoo bik thong dang

Length: Up to 180 cm, however usually around 140 cm

Range: This beautiful coral snake is found from around Phang Nga and south into Peninsular Malaysia.

Habitat: Usually found at some elevation – over 400 meters. Calliophis bivirgata prefers heavily wooded and wet areas of primary and secondary rainforest.

They seem to prefer living under and foraging under and on top of leaves and fallen trees and rocks.

Active Time: These corals snakes are found typically at night, but on rainy and cloudy days they can also be found to be active in the daylight, like some other coral snakes.

Description: Medium sized, though large for a coral snake, this snake reaches 140 cm typically, and up to 170 cm. or so, have been recorded. The body is mostly deep blue or black with light blue or white stripes along the lower ventral side of the body. The head, venter (belly), and tail are brilliant red. The nose is blunt for foraging the leaf litter where it spends most of its time. Dorsal scale count: 13-13-13.

Defensive Behavior: Always avoiding man and other large threats, they can be very fast as they flip about almost spastically. When they are trapped and tailed, they may attempt to flip over on the dorsal side, exposing a brilliant ventral of red, orange, and pinkish color. During foraging these snakes are very slow moving.

Food: Prey includes other snakes, lizards, frogs, birds.

Danger: All coral snakes must be treated as potentially lethal snakes. That said, many people free-handle these snakes at their own peril. Deaths have occurred as the result of envenomation by this snake. One man in Singapore was reported to have died within five minutes of envenomation. Do be exceptionally careful and never hand-hold any deadly snake.

Venom Toxicity: Neurotoxic venom which does not initially present with much pain at the bite site is immediately acting to block nerve impulses. The wound may become numb, and lips may also get numb. Difficulty in breathing occurs as the venom shuts down muscle contractions – the diaphragm and other major muscles.

Antivenom: None.

Key Diagnostic Features: Local pain + flaccid paralysis
General Approach to Management: All cases should be treated as urgent and potentially lethal. Rapid assessment and commencement of treatment for symptoms is mandatory. Admit all cases.

Offspring: Oviparous and clutches of 1-3 eggs.

Notes: One of the most impressive snakes to see in the wild. Fairly common in deep Southern Thailand and Malaysia mountains. This snake is easily confused with Calamaria schlegeli in Malaysia, Singapore, Bali, Java, and Sumatra. C. schlegeli is the Red-headed Reed Snake, which is harmless. The reed snake has smaller scales and no red tail or venter. Venter is grey and white.

King Cobra Washes Over Waterfall – Phattalung, Thailand

Robert Abrams sent me some photos of a snake he said washed over Menora waterfall he was relaxing at, the location is about 40 km outside of Ampur Muang, Phattalung province, southern Thailand. It was none other than the ultimate venomous snake, the king cobra.

In his words –

“It was raining very heavy that day. Some friends and I went swimming at a waterfall outside the town where we teach. All the sudden it was swept down into the pool where we were sitting. It was pretty stunned, i think it was in shock because the water was abnormally cold. It also had a break in the scales along its side. It was still alive at the time. It almost managed to make it out of the water, a friend and I tried to get a stick but by the time we found one it had been swept further down stream. It may well have survived, but i doubt it. I think enough time in that cold water and the beating it took going over waterfalls would eventually finish it off.”

Amazing! Some people never get to see a king cobra in the wild – and this one almost dropped in Robert’s lap.

I’m glad he didn’t reach it with a stick like he was trying to. Originally he thought it was a rat snake, which is harmless.

It looks to me like the snake was probably run over by a motorbike or other vehicle and went back into the wilderness to try to mend itself. It was likely ready to die though. That looks like a wicked injury.

Fastest King Cobra on the Planet? (Video)

It’s a sensational headline, but I thought it was important that you read this if you handle venomous snakes at all – and even if you don’t. (King cobra video below)

I got a call from my friend this morning. He told me they caught a 2+ meter king cobra at a palm plantation the night before. He said it was super fast.

King Cobras are fast when young…

Well, my first thought was – when they’re young and smaller like that – under 3-4 meters – yeah, they are quite quick. The juveniles up until about 2 meters are usually fast. I have yet to work personally with a king cobra less than 2.5 meters. I want to – but, will respect their speed a lot more. The juvenile king cobras are like a completely different snake than the big ones. They move differently – darting their heads around constantly, and very fast and short motions. The bigger kings are more deliberate in their movements and are much slower, even when straight from the wild. Not to call them slow – but, you can work with them to some degree without dying.

I took the motorbike over to see the snake after lunch. My friend was sleeping on a bench. I woke him up with a clamp down on his foot – as if a snake bit him. He didn’t jump or anything, so I was disappointed my trick didn’t work. No matter – he woke right up and showed me the beast.

He told me it had eaten two red tailed racers that morning, both of which were about 2 meters in length – but thin. I figured the king would be a bit slow and conserving energy as it digested all that food. I was so wrong.

This king cobra was black with light bands – very light, I wouldn’t call the bands yellow- they were more like a yellow/green. It was under 2.5 meters and over 2.0. It had a very long hood – and was really gorgeous to look at. My friend always goes the extra mile… when he opened up the gate and showed him his face we got a big surprise from this snake.

See the video of this super fast Ophiophagus hannah below:

This king came up that tree stump faster than any snake I’ve ever seen. Not that I’ve seen it all – however, I have seen many fast snakes – rat snakes of all sorts, tree snakes, big, small, thin and fast… and no snake has ever pulled one of these maneuvers on me.

I wanted to post this to give you an idea that you “think you know a snake” – but then one will do something you’ve never seen before. This has happened to me often as I learn more about monocled and king cobras. I’ve probably spent 200 hours working with them and studying them – watching other people work with them. I learned a whole lot in the first 50 hours and still, I’m always learning new behaviors and what these snakes are capable of.

Every snake species has a range of behaviors that they can exhibit. Snake handlers know, in general, what a snake is capable of – because it’s a certain species. However, there are snakes within the species, that, for whatever reason – learned behaviors that are different from most of the other snakes – and when they exhibit them – it can surprise the hell out of you.

Be careful with venomous snakes of all sorts – and never take them for granted.

Wagler’s Pit Viper – Venomous – Dangerous

Tropidolaemus wagleri - Wagler's Pit Viper - Dangerous
Tropidolaemus wagleri – Wagler’s Pit Viper – Dangerous and potentially deadly bites.

Tropidolaemus wagleri – also called: Wagler’s Pit viper; temple viper; bamboo snake; speckled pit viper

[Last Updated: 5 May 2017]

Thais say: ngoo keow took geh

Length: Average length of 60 cm. Male smaller than female. Female maximum length at 100 cm.

Appearance: Wagler’s pit viper is a short green (งูเขียว) pit viper and the female is considerably thicker (3-4 times as thick) than the male. A marked difference in patterns is noted with the female becoming darker and with strong banding as you can see in the above image. The males are so radically different that they look like completely different species (sexual dimorphism). In three reptile identification books I have for Thailand, they make no mention of the differences between the sexes. The female is pictured in each case.

Dorsal scale count ( 23 to 29 ) – ( 21 to 27 ) – ( 17 to 21 ) and usually 21 to 23 mid-body dorsal scale rows in males and 23 to 27 mid-body scale rows in females. Dorsal scales are strongly keeled in females, and lesser keeled in males.

Coloration can vary significantly among females. Here is a very yellow T. wagleri.

Here is a darker colored female, but not nearly as much as the top and bottom photos on this page. Not nearly as much lateral yellow as the previous photo.

This is a brightly colored Tropidolaemus wagerli (Wagler's pit viper) which is gravid and ready to have young. It is located in a tropical rainforest in Southern Thailand.
Gravid and ready to bear young. Soon to be the parent of dozens of hatchling vipers.

Besides the difference in size, thickness, and pattern, the body type is also quite different. The male grows to be around 60 cm and is long and thin, more like a wolf snake or something similar.

Below is a photo of a male Wagler’s pit viper found within one meter of a very gravid female. Obviously quite a big difference.

This is the male specimen of the species, Tropidolaemus wagleri. The female and male are markedly different in appearance of body, pattern, thickness, and coloration.

Range: Southern Thailand south of Khao Sok National Park, Suratthani province. Other countries: West Malaysia; Indonesia; Philippines. There is a concentration of these common vipers on the island of Phuket, Thailand.

Habitat: Elevations up to about 1,200 meters but most abundant at elevations from 400 up to about 600 meters in lowland primary forest, secondary forest and jungle – especially coastal mangrove. During the day these vipers can sometimes be found as little as a meter off the ground, up to a couple meters. They seem to prefer bushes over trees. Recently I found a gravid female at one meter off the forest floor and resting on a strong vine just 1 cm in diameter.

Active Time? Mainly nocturnal, but occasionally found during the day, especially during or after rain. Crepuscular in nature, they are more often active during dusk and dawn, or on an unusually dark day during heavy rain. I have found these snakes during the day in a moderate rain at 400 meters elevation, and at 2000 hours after a light rain.

Food: Birds – especially baby birds in the nest, mice and other rodents, lizards, frogs.

Defensive Behavior: Coil back into s-shape before striking. Strike is typically less than .3 meters in distance. Mouth wide-open exposing very long fangs and white tissue. Can strike in succession rather quickly. Their strike is not very fast in comparison with some of the other vipers. The heat-sensing pits between the eyes can sense temperature difference as little as 0.003 degrees Celsius. If continuously threatened they may hold their mouth wide open, like the photo above.

Venom Toxicity: Potentially deadly. Strong venom that usually does not result in death to humans. Victims experience a strong burning sensation upon envenomation, and swelling, necrosis of tissue. The multi-valent antivenom for green pit vipers treats envenomation by this snake.

Offspring: Live birth in September is common, with up to 41 young per litter. Male and females look different from day one, the females having light banding and the males with creme / red or brown dots on the top of the body.

Notes: Though these snakes are said to be exclusively arboreal and nocturnal, I found one on a mountain recently during the middle of the day, on the ground, during a rain shower. See the video below.

Siamese Viper – Venomous – Deadly

Daboia siamensis (Siamese Viper; Eastern Russel’s Viper)

Thais say: Ngoo Maow Saow

Length: Maximum of 1.7 meters. Russel’s around 1 meter long are common.

Range: These snakes are found around Bangkok, West, North, and East of Bangkok. The Russel’s photos shown here are from Sa Kaeo province near Cambodia.

Habitat:  These snakes are terrestrial and prefer grassy lowland, and open areas of all sorts. They prefer dry air and ground. Siamese vipers are not known to be found in dense rainforest or other very humid areas often.

Active Time? Nocturnal.

Food: Mostly rodents, but will target lizards and frogs as well.

Defensive Behavior: A loud hiss can precede a bite. When striking, it coils first and strikes. This snake is strong, so bites can be deep. Simple rubber boots are probably not sufficient to stop the fangs from penetration.

Venom Toxicity: Very strong. The rate of envenomation is estimated at 80% of bites. That’s high in comparison to Malayan pit vipers for instance, which is closer to 50%. Coagulopathy is common and necrosis is a possibility. Renal failure is common.

Russell’s Viper Antivenin is made at the Queen Saovabha Memorial Snake Institute in Bangkok.

Offspring: Need information for this section.

Notes: Across the globe, it has been estimated that bites from this snake kill more people than any other. This snake (Daboia vipers) are present across Asia and their bite is deep. They have strong fangs and their venom is very strong.

Russel’s have thick necks and they are the thickest of the vipers in Thailand, by far.

Color of Russel’s tends to be shades of brown.

A rather unknown occurrence – years after a bite, a man’s testicles may shrivel up, and there can be a loss of body hair. Info here.

Trimeresurus venustus, previously Cryptelytrops venustus – (Brown-spotted Green Pit Viper, Beautiful Pit Viper)

[Last Updated: 5 May 2017]

Appearance: Green snake (งูเขียว) with brown or reddish orange scales which may form bands across the width of the snake. Triangular pit viper head.

Thais Say: Haang Ham tai

Length: average 40-70 cm

Range: Chumpon to Krabi Province in Thailand. I have found them in Krabi and Surat Thani provinces.

Notes: I found this one in the picture on a small hill at a Buddhist temple on a hill next to some steps. These venomous snakes are active on the ground and in bushes. This one was in a bush about 1.3 meters high, right next to the path. It was non-aggressive and didn’t protest when I moved it away from the path with a stick.

Appearance: Small vipers with usually brilliant greens, whites, and browns. Though sometimes the color can be quite muted. Dorsal scales are strongly keeled. Dorsal scale count 21 – 21 – 15.

Habitat:  I’ve found these vipers up to 300 meters elevation. This snake hunts almost entirely on the ground where it preys on frogs and lizards. They also enjoy primary and secondary rainforest, limestone mountains, and rubber tree plantations. I kept one of these for three days to photograph and shoot video of. It spends most time suspended from a branch just a few inches off the bottom of the tank.

Active Time? The snake is mainly nocturnal. Active during the day only after heavy rainfall. I have found most of mine during daylight hours, but have also found them at night hunting prey on the ground in ambush position in culverts on certain hills.

Food: Mice, frogs, lizards. I had a good sized house gecko in the tank with this Trimeresurus venustus, but it left it alone. The pit vipers sense the heat of the animal and strike. The geckos are cold blooded so they are no hotter than their surroundings. Still, some pit vipers will eat cold blooded animals. Perhaps this snake just wasn’t hungry at the moment.

Trimeresurus venustus, the brown-spotted pit viper, aka: beautiful pit viper from Southern Thailand is one of the true vipers and is venomous but has not been shown to be deadly.

Defensive Behavior: This pit viper is very slow during the day and only bites if seriously aggravated. I ran into a reptile poacher in a Thailand forest and he was hand carrying one of these brown spotted green pit vipers in his left hand and had a large box turtle in his other hand. I told him – PIT! It means ‘venomous’ in Thai. He insisted “no, it wasn’t” and held it up to his face where the snake immediately bit him on the cheek a couple times and once on the lip. It let go after 1-2 seconds. He said – “See??” I promptly bought the snake from him, to keep him from further harm. Not sure what hospital he was at that night!

Venom Toxicity: Mildly toxic, but complications can develop. Bites are painful and usually without significant effects. Probably this viper would need to bite down for a number of seconds to transfer enough volume of venom that it would be seriously detrimental, but they are fully capable of doing so. Bites are to be considered potentially deadly. Green Pit Viper Antivenin is available at most public hospitals in Thailand.

Offspring: The beautiful pit viper I have now is likely gravid, which contradicts some other info I’ve seen about them having offspring in the June/July time-frame. This is December. She is not overly gravid and looks to be in the beginning stages, but still – I think only a couple of months are required for gestation. She’ll have an early birth – April maybe? These snakes birth live offspring in a jelly-like bubble that breaks after coming out of the female snake. Typical numbers are 20-30 young that are colored and patterned same as the adults.
