Found another one of these whip snakes – they are supposed to be either red or brown… I guess this could be called brown. The head is more brown. The neck and up to the stomach is silver… with some black patches… and then the tail is reddish brown. It could well be the red variety because as I compare photos with the other brown whip snake I had before – they are quite different in coloration. This one is predominantly silver – for the neck and down to the beginning of the tail. The tail gets dark – and there is a reddish tint to the brown… So, not sure.

Lovely snakes. These are vine snakes and very fast in the wild. I found him on the ground amongst leaves and rocks… sandy dirty. He was about to enter an 8 inch diameter drain pipe. It did take a bit to catch him – and once I got him he was fine – no bites until I had to grab his tail to pick him up. He was not ok with that and tagged my finger very quickly – a little blood.

There were people around and they were all screaming Pit Pit! (Venomous) It isn’t… Thais call all snakes venomous – which is part of the problem here – they kill any snake they see, insisting it’s venomous. The other part of the problem is that in Thailand there are 60+ venomous snakes. Most people can’t be bothered to study them all and know the difference. I don’t know all of them either.

This one I knew though. Great snake – will keep it for a couple of days and let it go where I found it.

Common names: Keel-bellied vine snake; keel-bellied whip snake; brown whip snake; red whip snake (more red).

Paradise Tree Snake (Chrysopelea paradisi) – Mildly Venomous – Not Dangerous

Full body of Paradise Tree Snake (Chrysopelea paradisi) from Krabi, Thailand
This one tried to bite many times and calmed after 10 minutes.

[Last Updated: 29 April 2017]

These are great snakes for a couple of reasons. Number 1 – their colors. This snake looks like Christmas – right? Amazing oranges, greens, and blacks make it very unique.

Number 2? They fly. Well, they glide very far when they jump from a high vantage point. They can glide dozens of meters – and probably more. These snakes are limited only by how high they are when they jump. Typically they use their gliding ability to travel from tree to tree in search of prey, or to elude capture by a predator.

Name: Chrysopelea paradisi. Paradise Tree Snake. Also called “Paradise flying snake.”

Length: As long as 1.2 meters (almost 4 feet)

Appearance: Very similar in all aspects to C. ornata with the exception of scale coloration. C. paradisi has black scales on the neck and body which have a green or yellow dot in the center of each scale. Scales on the dorsal near the vertebral column may have an orange or reddish coloration. Some call this the flower pattern. Great variation occurs as to how much orange is evident on the dorsal area – some have on the head, and completely down the body to the tail. Others have some orange on the head and a little bit on the neck, and none of the rest of the body.

Range: Thailand-wide. This one was found in Krabi province at sea-level in a handbag shop at the beach. We’ve found them in rainforest near a Thailand resort as well.

Habitat: Bushes, ground, trees, roofs. They are often found in palm tree fronds. I have found them there as well as small trees with big leaves and a lot of open area so they can see – presumably. I have found them as high as 500 meters vertically up a mountain in Thailand, and at sea level. Recently we found one 7 meters up a large tree on a hot sunny day.

Active Time? Diurnal – active during the day in trees and bushes, and occasionally on the ground.

Food: House geckos, Tokay geckos, lizards, bats, and frogs.

Defensive Behavior: They bite very quickly, but have small mouths and teeth. There has been no medically significant case of envenomation mentioned in the literature. They are considered harmless for humans and probably pets over the size of a cat.

Venom Toxicity: Weak for humans. Effective for geckos, frogs and bats. These are rear-fanged colubrids and a prolonged bite could cause swelling and pain at the bite site.

Offspring: They produce eggs which hatch during May/June in Thailand.

Notes: C. Paradisi is distinguished from C. ornata by the orange/red coloration at the top of the body, sometimes at the head, sometimes more of the body is colored, and sometimes the entire head and body are covered in the red flower like scale patterns.

These snakes are just like the golden tree snake and paradise tree snake but with a different coloring better for blending in with the dirt and leaves, as you see in the photo.

If you have any photos to share of Thailand snakes you’ve seen – send ’em!

Yellow Spotted Keelback – Venomous – Not Dangerous

These yellow-spotted keelback (Xenochropis flavipunctatus) snakes are rear-fanged and do have venom, however there are no reported deaths from them. The snake would need to bite hard and chew the venom into wound for a minute or so in order to really envenomate a human. Not many humans are willing to let a strong biting snake do that. Don’t you be the first!
