Dog-Toothed Cat Snake – Boiga Cynodon Photos

Amazing colors and eyes on the Boiga cynodon - yes?

Two photos of one of my favorite of all Thailand snakes – the dog-toothed cat snake. These are the longest of the cat snakes and get nearly 3 meters in length. They have a strange shaped head, as most cat snakes – and some would swear it was a viper. Many Thais see the triangle shaped head of these snakes and kill them immediately. Well, wait a sec, what snake DON’T Thais kill immediately?

These are primarily egg and bird eating snakes. Frequently they are caught after eating a bird in a cage, and they cannot get out of the cage. Birds seem to know this snake is a bird-eater because sometimes the way you find these snakes is to go see what the birds are squawking about – if there is one of these snakes in a tree near a nest – you’ll know it when the birds know it. All the Thai bird-keepers are familiar with this snake because they see them often.

These dog-toothed cat snakes have extraordinary patterns. The yellows and browns are amazing together and it’s definitely one of the most pleasant looking snakes you’ll find in Thailand – and maybe anywhere.

Here is another shot of the same snake, Boiga cynodon. It’s about 2 meters long. Notice the shape of the body, the cross-section. It has a very high vertebral ridge. These snakes can climb VERY well.

I've hand-held the dog-toothed cat snakes before and no problem... but this one struck at me repeatedly.

I have some video of a larger Boiga cynodon caught here in southern Thailand and a fact sheet for the snake at the link below:

Dog Toothed Cat Snake – Venomous – Not Dangerous

Dog-toothed Cat Snake found in Southern Thailand.

Dog-toothed Cat Snake - Venomous - Not Dangerous

Boiga cynodon (Dog-toothed Cat Snake)

Thais say: ngoo sy hang ma

Length: As large as 2.75 meters (8+ feet) Recently I caught one that was about 2.5 meters. They are thin snakes and have a pronounced vertebral ridge and color bands of tan, yellow, brown and black.

Range: These Dog toothed cat snakes are found only in southern Thailand from Prachuap Khiri Khan and southward to Malaysia. We found two Boiga cynodon in Krabi and one in Nakhon si Thammarat over the past year.

Habitat: Though they shy away from locations humans frequent they can be found on resorts in southern Thailand especially where there are chickens, eggs, and birds in cages. Typical habitat for the Boiga cynodon is the rain forest where they spend most of their time in the trees and bushes waiting on the perfect bird meal to land.

Active Time? Nocturnal, active at night usually – but, we found one during the day as well.

Food: Fowl of all sorts, and their eggs. Birds, chickens, and quail in captivity. When hungry will also eat other animals – lizards are most likely. There are herping forum postings of a captive animal eating mice.

Defensive Behavior: Rarely bites, this is a big snake that can be hand held.

Venom Toxicity: Though they rarely bite – even when physically attacked – they can inject venom. They are rear-fanged colubrids and a prolonged bite could cause swelling and pain at the bite site. The venom can cause problems with circulation. A simple bite from this snake is not usually dangerous because the rear fangs don’t sink in during a typical bite.

Offspring: Need information for this section.

Notes: These are beautiful snakes here in Thailand – perhaps more so than the rest of Asia where they are known to be found. A couple of specimens were found locally in Krabi in southern Thailand at night and near a chicken farm in one case, in a tree on another herping field trip. These snakes are known to eat local Thais birds in the cage, and then not be able to get back out through the slats in the bird-cage, and so entrap themselves.

Coloring on these snakes varies greatly. You can see the two snakes in these images here, they were both from the same area. They are dramatically different in coloration.

Dog-toothed cat snakes are sometimes confused with vipers because their head is quite pronounced in size from the size of their necks where it meets the head. There is no viper that gets anywhere near this big – so, you can discount vipers if the snake is 1.5 meters or longer. Only the Chain Viper (Russell’s Viper) reaches 1.5 meters, and it is considerably thicker in size at the neck.

Thailand Snakes

 

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.
