Thailand’s Very Common Non-Venomous Snakes

(Last updated: 26 July 2016)

Thailand has around 185 snake species considered non-venomous, or mildly venomous and not a threat to human beings. Though these snakes are not known to be dangerous to humans, that doesn’t mean that they are not. The red-necked keelback, for instance, was a snake kept in aquariums across the world for years before the first deadly bites occurred. Turns out that they have a very strong venom that can be delivered with prolonged or multiple bites. Do be careful with all snakes.

Chrysopelea ornata. Golden Tree Snake

These snakes are very common and it is probably the most commonly seen snake among tourists and Thai locals. They are at home in the bushes and on the ground during the day. They are excellent climbers and prefer to eat the tokay geckos and other geckos. These snakes have a mild venom that can kill or disable birds and other small animals. It is not likely to affect your dog or cat, if bitten.

Ptyas korros. Indo-Chinese Rat Snake

This rat snake is also very common no matter what type of weather or season. These are terrestrial (land-based) snakes with excellent climbing skills. They hunt lizards and other small animals on the ground during daylight hours. Rat snakes have no fangs, but their saliva is known to contain venom proteins. Nobody has been recorded in the literature as having been envenomated significantly by these snakes. Color varies from brown to grey or black.

Coelognathus radiata. Copper-headed Racer / Radiated Rat Snake. 

These rat snakes are common around trash bins, and anywhere rats and other rodents can be found. Though they are primarily terrestrial, I have seen one 3-4 meters up a palm tree raiding a bird nest of its young or eggs. These are strong, very fast striking snakes with a lot of nervous energy. Like the other rat snakes, it has no fangs with which to deliver venom.

Malayan Krait – Blue Krait – Highly Toxic Venom

White and black Malaysian banded krait. Very dangerous. Very toxic venom to humans.
Bungarus candidus. Malayan Blue Krait, Malayan Krait. Highly toxic and potentially deadly venom. White/black. Scroll down for 1 more photo.

Note: About 50% of all bites from this krait results in human death – even with the administration of antivenin (antivenom). Death is the usual result if no treatment is given. The closely related Bungarus multicinctus is ranked 3rd in the world for toxicity of venom based on some LD-50 data (terrestrial snakes). Do be careful.

(Last updated: 26 July 2016)

Bungarus candidus (Malayan Krait or Blue Krait)

Thais say: Ngoo tap saming kla, or ngoo kan plong

Length: Max length about 1.6 meters.

Range: All over Thailand and much of southeast Asia.

Notes: I’ve seen these dead on the side of the road near rubber plantations. Their head is not nearly as large as the yellow / black banded krait. The body doesn’t have the high vertebral ridge like Bungarus fasciatus. Be careful around these snakes.

Habitat: These snakes appear to favor flat country though I have found them on hills of 250 and 300 meters elevation. Not found higher than 1,200 m ASL often. Prefer proximity to water. Prefer rice fields and rice dams. Invades rat holes to use as a nest.

Active Time? The snake is mainly active at night and is not fond of the sunshine. They are shy and attempt to cover their head with their tail. They are active most consistently between 9 pm. and 11 pm. This is when I tend to find them.

Food: Other snakes – primarily, but also lizards, mice, frogs and other small animals.

Defensive Behavior: Not usually very aggressive. Shy. They don’t tend to bite unless really provoked. Still, you should never hold one. I have only seen one in a dozen of these snakes attempt to bite, and it was the result of being grabbed with tongs near the head.

Venom Toxicity: Very toxic – even more so than the Naja kaouthia (cobras). Bungarus krait venom is neurotoxic and attacks the human nervous system, shutting it down. Coma, brain death, and suffocation due to paralysis of the muscles and nerves necessary for crucial functions like the diaphragm, and or heart, are frequent causes of death. Death results usually 12-24 hours after an envenomed bite that is not treated. Little or no pain is usually felt at the bite location. The black/white kraits in Thailand are more toxic to humans than are the yellow / black kraits. That said, the yellow-black kraits (Bungarus fasciatus) can still kill you easily.

Here’s a short overview of what happened to one victim of a bite by Bungarus candidus (black-white striped krait):

A patient bitten by Bungarus candidus (Malayan krait) developed nausea, vomiting, weakness, and myalgia 30 minutes after being bitten. One hour later, ptosis and occulomotor palsies as well as tightness of his chest were noted. Respiratory failure requiring mechanical respiration appeared 8 hours after the bite and lasted for nearly 96 hours. The two bite sites were virtually painless and resulted in slight transient erythema and edema. No specific antivenin was available, and treatment consisted of respiratory support and management of aspiration pneumonitis. Recovery was complete. (Department of Medicine, Chulalongkorn University Hospital and the Queen Saovabha Memorial Institute of the Thai Red Cross Society, Bangkok, Thailand)

Handling: The banded and Malayan blue kraits are not known to bite during the daytime. That doesn’t mean they don’t, it just means they don’t do it commonly. At night these snakes bite rather easily, as evidenced by the numerous bites that occur at night to people usually laying down to sleep on the floor. Handholding the kraits for any reason seems rather absurd to me, yet snake-handlers across the globe do it regularly. The krait venom is so toxic, it’s just not worth the risk – however small.

Antivenin / Antivenom: There is a specific krait antivenin that is given for krait bites. If you don’t have access to that antivenin you can ask the hospital if they have Tiger Snake antivenin – which can be used as a substitute for krait antivenin and works well.

Offspring: Lays 4-10 eggs. Juveniles are 30 cm long at birth. Hatching occurs in June-July in Thailand.

Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Reptilia

Monocled Cobras – Venomous – Very Deadly

Monocled cobra siblings. Deadly venomous snakes - Naja kaouthia - Thailand
Naja Kaouthia – Venomous – VERY dangerous and very common Thailand snake.

(Last Updated: 26 July 2016)

Naja kaouthia, the monocled cobra is one of Thailand’s most deadly snakes – with highly toxic (neurotoxic + cytotoxic) venom. One bite on your toe from one that jumps out from under your outdoor refrigerator can kill you. Monocled cobras seem to be everywhere in Thailand. I had a friend that found them in his kitchen often. I’ve seen them crossing the road (see video below), and there was a family of these cobras living under the office of my wife’s workplace – with many 18″ baby cobras.

I just heard about Grant Thompson, an 18-year-old man in Austin, Texas that was bitten on the wrist by a monocled cobra and died of cardiac arrest. Authorities are looking for the snake. Tips that might catch the snake 1. If cool in the mornings, the snake might be found in bushes sunning itself. These cobras prefer hot weather over 80°F. 2. They are most active during daytime, but can move at night. 3. N kaouthia will eat eggs, mice, rats, if no other snakes are to be found. They prefer snakes, but I don’t know what Grant fed his snake. It might be unable to stalk prey and feed itself and die within a month.

Thais respect (fear) this snake because many have friends or relatives that have been envenomated (bitten and venom injected) by this snake. They even make Buddhist amulets with cobra snake images.

I’ve worked with two hatchling monocled cobras, and even at 12-15 inches – they are fierce. One snake handler described monocled cobras as “spastic” – and I have to agree.

If you are bitten by any cobra – get to the hospital as fast as you can. Monocled cobra venom is on par or even more toxic than some of the Thailand kraits, and much more toxic than King Cobra venom when compared drop to drop. Even if the bite is a small one, a nick, or a scrape, get to the hospital immediately. All it takes is a drop of venom to hit your blood stream for biological chaos to ensue.

Naja kaouthia (Thailand Monocled Cobra)

Appearance: Monocled cobras are easily identified by looking at the back of the hood – there is a monocle – or eye type shape there. They are light brown to dark grey to solid black. Most are very close to black.

Thais say: Ngoo how hom, Ngoo how mo (long o sound)

Length: Typical maximum length about 1.5 meters. Recently I saw one in a mangrove forest that was 2 meters long, a giant. They can get up to 2.2 meters – about 7.5 feet long.

Range: All over Thailand and most of Southeast Asia.

Notes: Neuro toxic venom affecting nerves, brain, and causing death very quickly without treatment. They are very fast strikers. The baby monocled cobras are every bit as deadly. Please be CAREFUL!

Habitat: Both flat and hilly regions. I’ve seen them on hills, but usually near people – under houses and in places rats and frogs are likely to be found. I’ve seen them most often in residential areas bordering forest, or near the ocean. In the mornings they can be in trees and bushes – trying to get some sun to warm up. They love to hide under leaves, wood, anything really. Lifespan is around 30 years.

Deadly venomous Thailand monocled cobra (naja kaouthia) in strike pose.Active Time? The snake is mainly diurnal – active by day, but I have seen a number of them still active at night. In fact, in Thailand – I’ve seen about a dozen active at night – the rest were active during daytime.

Food: Rodents, lizards, frogs, birds, eggs, other snakes.

Defensive Behavior: Lift head off ground and flatten out neck. The hood flares quite wide compared to the width of the body. When comparing the monocled cobra and the king cobra, the monocled cobras have a hood flare that is more extreme in relation to the width of their body and heads. They can hiss when they strike.

Monocled cobras are very active and ready to strike especially as the temperature climbs past 35°C (about 95°F). Do be very careful with them during this temperature range because they are very easily agitated and strike much more often.

Venom Toxicity: Very toxic, deadly. Even a small bite can kill you. See “neurotoxic and necrotoxic / cytotoxic venoms” (link).

Offspring: Lays 25-40 eggs. Young are fully prepared to envenomate as they hatch. Mating takes place after the rainy season. Eggs incubate in about 2 months. Eggs hatch between April-June. Hatchlings are between 8 to 12 inches at birth.

Thailand’s 3 Very Common Venomous Snakes

 (Last Updated: 26 July 2016)

Thailand has approximately 60 snake species that are considered venomous and potentially dangerous to human beings. 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.

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

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.

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. 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.

(Last updated: 26 July 2016)

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 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, that 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.

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

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

(Last updated: 26 July 2016)

Length: Average 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 even attempt to bite. The mouth on the Calliophis maculiceps is very small.

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.

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 Bangkok and south toward 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 leaves and fallen trees to rocks.

Active Time: These corals snakes are nocturnally active, but on rainy and cloudy days they can also be found to be active, 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 with light blue or white stripes along the lower ventral side of the body. The head, venter (belly), and tail are usually 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.
