Oriental Whip Snake - Venomous - Not Dangerous

The oriental whip snake is a very common rear-fanged venomous snake found here in Thailand’s rain forests. You can find these snakes in the trees during the day, I have even seen them crossing my path twice on trips up a small local mountain in southern Thailand.

The beauty of these snakes is legend. There are green,brown or yellow versions of this snake, all of which are spellbindingly beautiful. The juvenile whip snakes are often brown or yellow.

Ahaetulla prasina (Oriental Whip snakes)

Thai Language: ngoo kee-ow hoo-uh jing joke pa

Length: Up to 190 cm. Girth: Body is finger thin, tapering to a very thin pencil-width neck. The head is spear shaped and bright green.

Range: All over Thailand. The species ranges from India to China and throughout Southeast Asia.

Habitat: During the day you can find these snakes in trees and bushes usually. Occasionally they will be at ground level hunting frogs and small lizards. I have seen these snakes in all kinds of habitat, but usually in trees and leafy bushes. At night these snakes sleep in the same environment.

Active Time? Diurnal – active during the daylight hours.

Food: Frogs, small birds, small lizards.

Defensive Behavior: The oriental whip snake can spread it’s neck area to increase by double in size as a defensive technique designed to scare attackers. It is quite beautiful when either solid green, or with the green, white and black checkered pattern displayed in full defensive posture. Sort of comical is what the snake does with it’s tongue when molested. It sticks the tongue out and holds it there for some seconds, or minutes.

Venom Toxicity: Weak. Although this is considered to be a rear-fanged and venomous snake it is not very dangerous to humans due to it’s non-aggressive nature and weak venom characteristics. The venom would need to be injected into the wound with time – with a chewing motion. Not many people bitten are going to let a snake hang off them for any amount of time. Some do, and they may have severe complications and require hospitalization.

Offspring: In Thailand the Ahaetulla prasina can mate during either of two times. Usually between April and July, and then also between December and January. Gestation period: ~ 6 months. Number of births: 4-10. Lengths at birth of offspring: 400 – 500 mm.

Notes: These are wonderful little snakes to catch and let go. These snakes do not do well in captivity and many die within days of being kept in an enclosure. They are as beautiful as snakes get, but please resist the urge to capture one to keep as they are very sensitive and die easily.

We have not been bitten by these snakes, but in the wild when catching them they will attempt to strike at times. They are fast and have a short striking range. What is really amazing about these snakes is the way they effortlessly glide down a hill or through trees like on ice. They can climb extremely fast and disappear before you have a chance to grab them. See video below!

These snakes are not often confused with other snakes here in Thailand because they are quite distinctive. Their head is long and to a fine point. They are very thin at the neck before the head unless they have flared up in defense.

Red necked keelback (Rhabdophis subminiatus) is now classified as a deadly venomous snake.

Red Necked Keelback – Venomous – Dangerous

Red Necked Keelback Snake, venomous, Thailand and southeast Asia.

A beautiful snake, usually under 1 meter, not very aggressive.

Rhabdophis subminiatus (Red-Necked Keelback Snake)

Thai: (ngoo lay sab ko dang)

Length: Up to 130 cm (1.3 meters). Usually smaller than 1 meter.

Range: Thailand and southeast Asia.

Notes: These snakes are commonly found near water, lakes, ponds, and in gardens. Recently a friend had one in his swimming pool in Krabi town, southern Thailand.

Active Time? Daylight hours

Food: Frogs and fish primarily

Defensive Behavior: Spread out their neck slightly to make themselves appear bigger. Not as dramatic as a cobra. Lift their head and neck off the ground 4-5 inches.

Venom Toxicity: LD50 is 1.29 mg/kg for intravenous injection (source). That is about the same rating as the very deadly “Banded Krait (Bungarus fasciatus)”. It was previously thought these snakes were harmless. Some kept them as pets and were bitten. In one case the snake was left to bite for 2 minutes before removing it from a finger. Serious complications resulted requiring hospitalization and intensive care. Click for article. These snakes are rear-fanged and need to bite and hold on, or, repeatedly bite to have any effect on humans. Once they do either – there is the possibility of severe problems including renal failure and death. Recently a small boy of 12 years old was bitten by one in Phuket, Thailand and he is currently being treated (11/5/10). Be very careful not be be bitten by these snakes. There is NO ANTI-VENIN available yet for these snakes.

Another study in Japan ranked the venom as having an LD50 of 1.25 mg/kg for intravenous injection. (Japan Snake Institute, Hon-machi, Yabuzuka, Nitta-gun, Gunma-ken, Japan) V.1- 1969- Volume(issue)

Update: The 12 year old boy bitten by the Rhabdophis subminiatus was treated for 2 weeks of intensive care, and released. He was bitten multiple times, the 2nd bite lasting over 20 seconds.

Offspring: I have a juvenile red-necked keelback at the moment but I got it after the fact – found in the wild. Will find more info to put here.

Notes: These snakes can inflict a deadly bite when they are allowed to bite for longer than a couple of seconds. I know personally 2 instances where a child was bitten for well over 20 seconds, and a man was bitten for about a minute. Neither wanted to hurt the snake to remove it forcibly, and both spent over a week in intensive care, with the possibility of renal failure and death. Do not play with these snakes. If you have one, do not free-handle it. Treat it like you would a pit viper or a cobra. The LD50 on this snake for intravenous was stated to be 1.29 mg/kg. That is VERY venomous.

Order: Squamata
Suborder: Serpentes

Species: Rhabdophis subminiatus

Cobras in the HOUSE!

Welcome to Thailand Snakes…

Thailand has 200+ snake species with over 60 of them - venomous. I created this site as a way to educate Thais and visitors to Thailand about snakes. Many people kill the snakes they see in Thailand, while in many cases - they are non-venomous and completely harmless. With this site I hope to give people a better idea what is harmful and what isn't.

Browse the many snake photos and videos here so you can identify snakes you see on your porch, in your bed, or underfoot.

If you have been bitten by a snake - go to a hospital FIRST. Don't waste time looking it up on the internet. With some snakes you need to have medical help as fast as possible. With others you have some time. I know a Thai man whose brother died in less than 10 minutes from a snake bite.

There are venomous (some say 'poisonous' erroneously) snakes everywhere in Thailand. Friends have had cobras in their kitchen, and others had kraits in the garage. Vipers love bushes and trees near water and walkways.

Bookmark this site so you can quickly identify snakes you have seen. Notice the variety of venomous and non-venomous snakes in Thailand - and realize that they come in all sizes, shapes, colors, and patterns.
