Snakes in Thailand

There are many snakes in Thailand that are both exotic and interesting. Whether you are planning a trip to the tropical country or are interested to know what species of snakes roam it, you have come to the right place.

Thailand has over 200 different snake species, but we will mostly cover the most common ones as well as some interesting species that you can find in the country.

In Thailand, endangered and poisonous snakes are not allowed to be sold, kept, and traded. The sale, import, trade, or purchase of any protected Thai wildlife is illegal.

If you are bitten by a poisonous snake, there should be antivenom available at the nearest hospital as snakes are not a rare thing to come by in the country of Thailand. 

Snakes can be found in yards and even randomly while driving around you can encounter them.

Keep yourself safe and learn to identify the poisonous ones to the non-venomous ones. Here are some species of snakes you can find in Thailand.

Lambert’s sea snakes have a similar body shape to other sea snakes. They have a flat body, narrow head, and paddle-shaped tail.

They are tan or brown on their top, with dark striped blotches running down their body. Their underside is white, and they have dark markings on their head.

This species is extremely venomous like other sea snakes but does its best to avoid humans. It feeds off small fish it finds on the ocean floor, but may occasionally travel into fresh water.

Lack of studies and a secretive lifestyle is why learning about this species can be difficult. This species shares many similar traits with other sea snakes like their ability to dive deep into waters.

Robust sea snakes have thick bodies and large heads. Their body is wider than their tail and is flat to help them swim.

Their tail is also shaped like an oar and allows them to move through the ocean freely. This species is also called the black-banded robust sea snake because of the large black bands that cover its body. White is the color of the other parts of its body. 

This species spends most of its time in the ocean, so bites are rare. They are sometimes found along the seashore, in river banks, and coral reefs in the areas they live in.

Harmless like most other sea snakes, this species is only dangerous for people going into its habitats, like fishermen or divers.

This species is named after Patrick Russells, who is a herpetologist who specializes in Indian venomous snakes. The Russels sea snake is long and has a dark body.

It is similar to other sea snake species as it has a paddle tail and other features that help in its lifestyle.

Not much is known about the Russells Sea snake because of the lack of studies done on the snake. This species has other similar qualities to other Hydrophis species, like eating fish, and its pelagic lifestyle.

Russell’s sea snake and Russell’s viper (Daboia russelii) are not the same species. Both of these species are found in Thailand, and are named after Patrick Russells but belong to two different snake families.

This species can be green, to gray, and is covered in dark bands. The bands in older snakes will begin to fade. The belly of this snake has white or yellow coloring.

Ornate reef snakes are venomous but are much more aggressive than other species of sea snakes. They can become aggressive easily, and their odd movement on land makes a bite more likely to occur.

They have a paddle-tail to help them swim and nostrils that will stop saltwater from entering. Colors for these snakes will vary as some can have a dark belly with a yellow back, while for others it is the opposite.

The yellow-bellied sea snake is able to survive 7 months of dehydration since the ocean lacks fresh water. They mainly feed on fish and swim backward to capture them.

Conclusion

In Thailand, there are around 230+ snakes in the country. Having so many snakes in the country makes them common to come across, and some of them are extremely deadly.

Deadly snakes like cobras and vipers are feared, but most snakes are harmless if left alone. The abundance of snakes makes it dangerous to walk in tall grass, but they can always find their way out of the wild.

In this article, you got to learn about just 102 different species in Thailand, but there is much more that you can find in the country. In southeast Asia, snakes are a common animal, living in mountains, deserts, forests, cobras, wetlands, and many other types of habitats.
