I just completed an Info Graphic about Thailand Snakes that you might find interesting. It’s located here:
Thailand Snakes Info Graphic (Data collected from June, 2011 to November, 2014)
I’ve considered, on a couple of different occasions, creating a large database of snakes in Asia that could be used as a reference tool for anyone that wanted to join (free). I was thinking, start with Thailand snakes first. The data on each snake would be as comprehensive as possible. At the moment there are separate resources we can use to find information about specific species. The information is not up to date in most, and is not comprehensive by any means.
If anyone is interested in joining this project, do let me know. If there is enough interest, we can move forward with it. Information for each species would be exhaustive. Everything that is known about each. Photos of hatchlings, juvenile, and adult snakes. Photos of snake skins. Photos of eggs. Photos of environment typically frequented. Venom characteristics. Links to articles in the literature that provide more scientific information. Links to venom experts in the case of envenomation. Scale counts would be included. Latest finds would be included. New snakes not yet classified will have pages.
There really needs to exist a comprehensive database with everything that is known about a particular species, in one place online. This database would be an attempt at that.
This would be an ideal project for students looking to gain notoriety in the field and to make contacts with other snake enthusiasts around the globe.
Just a thought at the moment. Anybody want to move forward with it?
I was getting in one of my mountain climbing workouts and on the dead tree next to me was a small (50cm) dark green snake coming out of a hole where it looked like termites were munching wood. He was head down and just gliding slowly down the vertical trunk of the tree.
I ripped off my shirt and softly grabbed it. I’ve caught 3 of these same species of snake before, and none of them bit or struck, but I don’t take any chances when I don’t know what kind of snake it is.
I had my friend give me a plastic bag and I put the snake in there until I could drink all my water from a bottle and transfer the snake into the bottle. It was 10 minutes before I would find something to poke holes in the bottle. I let air in twice during that time. I’m always scared they don’t have enough to breathe.
I got home and tried to shoot some photos and video, but the light is horrible today and the snake was not cooperative at all. It is calm, but it is calm and full of energy. It never stops in one place so I can get a good photo. Hence the photos I’ll upload to this page are not perfect. Will work on getting better images tomorrow.
Also tomorrow I’ll try to get scale counts and some better video. It’s exciting to know that very few (or nobody) has seen this snake before. It isn’t described in the literature for Thailand. Maybe it came up the peninsula from Malaysia. Not sure. Anyway, enjoy the pics. Will post more as I get them.
I found a snake that appears to have never been found in Thailand before today on my hike at a nearby mountain in Thailand.
Time: 12:10 PM, 4/20/2013
Elevation: ~ 400 meters.
Weather: 34C. Bright sunshine, though the area the snake was in was shaded by the canopy.
Habitat: Leaf litter right off the main trail. This is a limestone mountain with sand / dirt topsoil. This snake was in an area with no water for 150 meters or so. It was dry in the leaves, but it had rained within the last 2 days there.
Time observing: About one minute before it successfully evaded capture through the bed of leaves.
Morphology: Approximately 70 cm in length. Width of body at the thickest part was about 5.5 cm (diameter). There was little difference in the thickness of the body from the neck down through the body. The tail tapered very gradually, and so was long. The head was about 4.5 cm in diameter. Body of snake was uniform in color, a light yellow – almost mustard color. The neck was slightly red for a length of about 5 cm. Head of the snake was the same mustard color, without dark markings typical of some keelbacks. It had the shape of a keelback head, the eye size was consistent. The head was the same yellow color as the body, and then had a white ring that went from under the jaw, around to the back of the head where it meets the top of the neck. It was a closed loop on the top, though I didn’t see under the jaw. The scales were bright and very clear. The eyes were very clear. I was approximately 60 cm from the snake. It was not in shed. There were 2 small dark dots, no bigger than about 1 mm each on opposite sides of the vertebral column, and these continued the length of the body, stopping at the tail. I could not see the belly of the snake.
Details: I was walking back from the top of a mountain peak and was well under the canopy. On my right I heard a little twitch of an animal in the leaves, just a split-second, and it stopped. I looked down, and very close to my right foot was this beautiful little snake. At first, just looking at the tail, I figured it was a light-colored Rhabdophis subminiatus. When I bent down and took a good look, the body morphology, color, pattern, and head were completely different from any other snake I’ve seen in Thailand. I had a snake bag with me, to carry my water in. I quickly ditched my water and wrapped the bag around my hand and watched the snake for a while, waiting to get a better opportunity to make an attempt to grab it. The snake started moving again, head under the leaves, and then popping it up again where I could see it. I made a grab for the neck, thinking I’d just pin it down in the thick leaf litter and better be able to grab it to put it in the snake bag from there. After my hand came down, it was able to slip out forward, then launch itself over the back of my hand and back down into the leaf litter where it was lost in seconds. I spent 10 minutes looking, and then headed back down the trail, remembering precisely where I saw the snake.
I’ve seen many keelbacks and many other snakes here in Thailand – hundreds. I’ve not seen one of this color or morphology before. When I returned home I promptly checked Google image search for keelbacks, Sibynophis, and other snakes that I thought it could possibly be. I found no images anything like this snake. I checked the “A Photographic Guide to Snakes and Other Reptiles of Thailand and South-East Asia” by Cox et al, and did not find this snake listed.
I think there must be dozens of new, never before classified snakes to be found in Thailand. Thais are not what I’d consider outdoor types, and there are few people in the country that study snakes to any degree. One researcher mentioned a handful that were actively practicing in the country.
If you are interested in finding new snakes, I do suggest you book your flight to Thailand at your most convenient opportunity, and plan on spending a month or more looking. Give me an email if you are going to be close to Krabi province. Oh, and don’t forget your camera, like I just did!
This is a snake found in deep southern Thailand that I’ve not written anything about, but some conversation last night reminded me to put something about online as a warning to others that might encounter or even keep this snake in captivity.
The Blue-Necked Keelback, Macropisthodon rhodomelas is a small colubrid snake that looks innocuous enough, but is one that has the potential to cause some serious damage. I was reading a scientific paper from a man in Singapore that had one captive, that bit down on his finger and chewed for a bit before releasing him. This 120 kg man (264 lbs) fell to the floor a minute after being bitten by this snake. Here is the complete paper on PDF. It would be great if you’d share this page with anyone that you know who keeps snakes, as this snake is frequently regarded as harmless, like the Rhabdophis subminiatus (Red-necked keelback) once was.
Well, 2012 was a great year for herping, and I found a lot of snakes to add to the list of new species I’ve seen. I enjoyed the year quite a bit, and I was able to get out during the day a lot more than I have previously. I have to say, the daytime snakes, with the exception of the King Cobra, and Monocled Cobras, are not all that worth going out in the heat for. I much prefer night time snake hunting.
During the night you can find not only the most interesting group of snakes, but many lizards, geckos, spiders, scorpions, bats, owls, centipedes, and other beasties. Night time is the right time for looking for snakes in Thailand.
I’ve had a number of requests from readers of the site and from Youtube viewers, to go herping this year that I just couldn’t manage. I have to say, I got dozens of requests this year to join people for herping, and for those that look at me as a tour guide to introduce them to the basics of snake hunting.
I have to say honestly – I’m not interested in joining beginners for herping in Thailand. I don’t enjoy the responsibility. I haven’t enjoyed in the past, people that couldn’t follow the few safety guidelines I gave them before we started. I am interested in herping with experienced herpetologists and amateurs that know something already about snakes – whether native to Thailand or some other spot in the world. If I’m not learning anything during the excursion, then it isn’t really worth it for me. I enjoy teaching people about snakes, but my time is so limited, I’ve got to be getting something out of it in the way of education, or it probably just isn’t worth it to me.
In the previous year I had over 800 requests for identification of snakes – through the online form there in the upper right side of the all web pages on the site. That’s pretty amazing. I wish I had the time to respond within 24 hours to each request I get, but again, time is at a premium and it usually takes me a few weeks, and even months, to respond to requests there. Eventually I do respond, so if you have a non-urgent snake ID request, submit it there and I’ll get to it as time permits.
If you have photos – just send them immediately to: firstname.lastname@example.org and I can usually respond within minutes. I am on the computer much of the day, and when I see a request with photos come over the email – I answer immediately. I answer fast because I don’t want the snake to be killed, if there is a chance of that. Secondly, and of course more importantly, I don’t want anyone to mess with dangerous snakes, so I want to ID it quickly and let people know if the snake might be deadly or dangerous.
In 2013 I hope to finally publish a free ebook I’ve been working on for a couple of months, Snakes of Thailand. This will be a book you can put on your mobile phone, iPad, computer, whatever electronic device you have – so you can identify some of the snakes you see. I’ll list some information in the book, but mostly it will be full of photos and some quick facts about whether it is deadly or not – along with some key identifying features to distinguish between snakes that look similar.
I have not posted many photos from viewers that sent them to be posted on the site in 2012. I have hundreds that I just didn’t have the time to post. I’m tremendously busy with some other pursuits, and expect to have little free time in 2013 for fun stuff involving snakes.
If you want to write any articles about Thailand snakes, or any Thailand wildlfe or environmental concerns – whether it includes snakes or not, send it to me by email. I may be open to posting it, depending on the content.
Have a great 2013…
I sent photos of a snake just like this one to a couple biologists about 5 months back. Nobody could tell me what it was, based on appearance. A couple guys that have found new species in this area have said it is, without a doubt, from the Oligodon genus. They asked that I do scale counts. I had to figure out what a scale count was. Today I just went through some snake scale diagrams to figure out some other things. Pretty fun stuff, playing amateur biologist.
If you know what this snake is by the information given below – do let me know!
Geographical location: Southern Thailand, Krabi province.
Elevation found: 200 meters
Habitat: On ground, with head buried in hole near garbage can on limestone mountain.
Length: ~ 36 cm.
Girth: 5-6 cm at mid-body, thickest section.
Loreal scale? Yes.
Postocular scales: 3
Ventral scale count: 160
Ventral pattern? Yes, irregular spots (yellow/white) and shapes toward the middle of each scale. Outer edges of ventral scales are grey to dark grey. I have also caught one of these snakes that looks the same except the ventrals are grey without spots.
Gular: 4 sets of 2. I’m a bit confused about this. Are ventral scales ONLY solid – if they are solid the whole way down the body? Because there are 4 rows of split scales that could be called Gular I guess… but if ventral scales can be split too – they could be included in the ventral scale count.
Subcaudal scale count: 51. They are split.
Anal: it is solid, just one scale, not split.
Scale counts: Diagonally 17. Alternating back and forth straight over and to the other side: 17.
Color: The true color of the top of the back of this snake is dark olive green. It lightens slightly going toward ventral side. The head is slightly darker overall than the body, but not much. The side view of the head (below) isn’t a true color representation.

I was going to wait until I had time to post this, but I just can’t – I’m too excited to show it to you all.
This was sent to me by John Oles from Udonthani, Thailand. Instead of retell the story, I’ll post what he sent to me:
I live 18km outside of the city of Udon (NE Thailand). About 3 weeks ago a friend was visiting our property. After supper, I took him to the far corner of our yard to view the fireflies, about 8PM. The area is heavily shaded (during the day) with native trees and is on what my wife calls a giant termite pile (emphasis on giant). It’s pretty much a swampy area, except for on the approximately 30m square termite pile. The area has mongoose, wild ducks, and white rump shamas as well. As we were entering that area, we noticed a yellow krait off to the side of the trail. When we looked closer (but not too close!), it appeared to be one krait (the shiny one) eating another krait (the not so shiny one that’s on the other side of the netting). But as we observed a bit closer, we could see the tails of the two snakes intertwined, apparently mating.Our best guess was that the shinier of the two kraits was about 1.5 meters, while the duller of the two appears to be slightly shorter.The snakes made no attempt to strike. The male finally broke away from the female after we observed for about 10 minutes…….that’s when we left as well.
Hope this provides some insight into the yellow kraits in the NE of Thailand.
It definitely does provide some insight. Establishing that banded kraits (Bungarus fasciatus) mate at night in Udonthani in October – on 10/9/11. It also shows that barriers to sexual union might not be barriers at all. Species can cross from one habitat to another despite barriers. Sure it’s not a river, but it’s something to see that snakes disregard the net between them and find a way to mate with the obstacle between them.
If you look at the close up photo – they appear to be mating from opposite sides of the netting. Is that great, or what?

Bungarus fasciatus snakes mating – close up. Netting of fence seems to be between them:
There is very little on Wikipedia about the breeding behavior of these snakes, I’ll post what is there and have a look around for more information to post later.
From Wikipedia for Bungarus fasciatus:
Little is known of its breeding habits. In Myanmar, a female has been dug out while incubating a clutch of 8 eggs, four of which hatched in May. Young have been recorded to measure 298 to 311mm on hatching. The snake is believed to become adult in the third year of its life, at an approximate length of 914mm
From Joachim Bullian’s “Siam-Info.de” – a great resource for snake information:
The mating season for this subspecies (Bungarus fasciatus) is in the months of March and April. About 2 months after mating, the female lays 4 to 14 eggs. The females remain with the clutch of eggs until the young animals have hatched. Contrary to pythons these snakes do not incubate the eggs but only guard them. The incubation period of the eggs amounts to between 60 and 64 days. The new born animals are between 32 and 34 centimetres long.
So, these snakes mating in October shows that there are multiple times of year these snakes are capable of mating in Thailand. Perhaps it varies by location in Thailand?
The Ptyas carinata (keeled rat snake) I caught on the mountain last night had an eyecap that was lodged in the eye-socket and not coming out anytime soon. I’d never removed one before, but, having watched some video about it – I thought I’d give it a try.
What Are Snake Eye Caps?
Snakes have no eyelids, and the skins they shed regularly – covers the eye as well. When the snake skins shed – fall off – there is the covering for the eyes that comes off as well. When they don’t shed with the rest of the skin and get stuck over the eye – they are known as eye caps, or retained eye caps.
Snakes with mites or other infections around the eye might retain the eye caps after a shed, and this is probably what happened to my rat snake, as he had an obvious infection of some sort around the eye.
First I held the rat snake’s head with my right hand and touched the eye cap with a piece of cloth to see how she reacted. No reaction. I wanted to see – was she going to really get agitated if I tried to remove it? She didn’t. Then, using a piece of tape I rolled up into a little stick I attempted to brush against the eye cap from the nose to the neck… hoping it would come off. It did not. The snake still wasn’t agitated. I took a jeweler’s screwdriver and very gently eased it under a little ridge of the eye cap and lifted the cap slowly. The snake was still not having a bad time of it – so I kept going. Eventually it was off completely. Then she livened up because she could see how close I was to her.
Feels good have the snake better off for having seen me, not worse off.
I will let this keeled rat snake go at the Thailand mountain I found him on, but in a different location. There is a place I know they are always complaining about the rats. This snake will help with that.
Will shoot some video and photos as I let her go, but it’s with the iPhone – which isn’t the best, but hopefully will give me something usable for YouTube. These keeled rat snakes in Thailand are lovely animals – I hope you get to see one sometime. They are non-venomous, and though they bite if agitated, they can also be hand-held if you know how to do it.
