Common Snakes of Thailand

Non-venomous snakes

Burmese Python

The Burmese python is one of the largest snakes found in Thailand. It can grow up to 3 meters long and is non-venomous.

The Burmese pythons are powerful constrictors, preying on rodents, birds, and even small mammals and they are often found near water sources, and they are excellent swimmers.

They have an incredible ability to flatten their bodies and blend into their surroundings.

Mildly venomous snakes

Keelbacks

Keelbacks are a group of colubrid snakes and they are named for the keeled scales on their backs, which give them a rough texture. Some keelbacks, like the red-necked keelback (Rhabdophis subminiatus), are mildly venomous.

However, they are not typically dangerous to humans.

Bronzeback Snakes

Bronzeback snakes are a group of mildly venomous colubrid snakes and they have a distinctive bronze-colored dorsal stripe and feed on lizards, frogs, and rodents.

Although their venom is mild, they are fast-moving and can be defensive if threatened.

Venomous snakes

King Cobra

The King Cobra (Ophiophagus hannah) is the world’s longest venomous snake, reaching lengths of up to 5.5 meters.

It’s considered one of the most dangerous snakes in Thailand due to its potent venom and aggressive behavior when cornered.

The King Cobra primarily feeds on other snakes and is found in various habitats, including forests, grasslands, and agricultural lands.

Monocled Cobra

The Monocled Cobra (Naja kaouthia) is a highly venomous snake found in Thailand. It’s known for the distinctive “monocle” pattern on the back of its hood.

Monocled cobras are often found near human settlements, and they primarily feed on rodents. These cobras can spray their venom, making them particularly dangerous.

Banded Krait

Banded Kraits (Bungarus fasciatus) are venomous snakes and they have a distinct banded pattern of black and yellow or white bands, and they primarily feed on other snakes, rodents, and small mammals.

Banded kraits are highly venomous, but they are nocturnal and generally not aggressive, reducing the risk of human encounters.

Malayan Pit Viper

The Malayan Pit Viper (Calloselasma rhodostoma) is a venomous snake found in Thailand.

They are usually brown or black, with a distinctive triangular head and heat-sensitive pits between their eyes and nostrils. These pit vipers have potent hemotoxic venom that can cause severe tissue damage and bleeding if left untreated.

Reticulated Python

The Reticulated Python (Malayopython reticulatus) is the world’s longest snake and can grow up to 10 meters in length. It is found in Thailand, particularly in forests, grasslands, and near water sources.

Although it is a non-venomous constrictor, its large size makes it potentially dangerous if it feels threatened.

The Green Pit Vipers are arboreal and feed on small mammals, birds, and lizards. Their venom can cause severe pain and swelling but is generally not life-threatening to humans.

Snake Habitats in Thailand

Bangkok and urban areas

Snakes near human settlements

Many snake species are found near human settlements in Thailand, including the monocled cobra and the Indo-Chinese rat snake. These snakes are often attracted to urban areas by the presence of rodents and other food sources. It’s essential to be cautious and respectful of these snakes in urban environments.

Snakes in Bangkok’s parks and green spaces

Bangkok’s parks and green spaces provide a refuge for various snake species, including the oriental whipsnake and the golden tree snake.

Natural habitats offer shelter and food sources for snakes, making them an essential component of the urban ecosystem.

Rural and agricultural lands

Snakes in lightly wooded areas

Lightly wooded areas are home to numerous snake species, such as the king cobra, banded krait, and keelbacks.

These habitats provide shelter, food sources, and nesting sites for snakes, contributing to their overall survival and reproduction.

Snakes in agricultural lands

Agricultural lands host a variety of snake species, including the Indo-Chinese rat snake and bronzeback snakes.

Snakes play a crucial role in controlling rodent populations in farmlands, helping to maintain a balance in the ecosystem.

Forests and natural habitats

Snakes in Southern Thailand

Southern Thailand boasts lush tropical forests, which are home to numerous snake species, including the green pit viper and the reticulated python.

Dense habitats provide ample resources for snakes, contributing to their survival and reproduction.

Snakes in grassy and flatland areas

Grassy and flatland areas are also suitable habitats for snakes like the Malayan pit viper and the golden tree snake.

These environments offer ample hiding places and prey for snakes, allowing them to thrive.

Snake Behavior and Adaptations

Diurnal and nocturnal snakes

Some snakes in Thailand are active during the day, like the oriental whipsnake and the golden tree snake. Others are nocturnal and are more active at night, like the banded krait and the Malayan pit viper.

Understanding these patterns can help reduce the risk of encounters with dangerous snakes.

Snake diets and hunting strategies

Snakes eat a variety of prey, including rodents, birds, lizards, and frogs. Some snakes, like the king cobra, specialize in hunting other snakes.

Snakes have various hunting strategies, such as ambush hunting or active pursuit, depending on their species and the prey they target.

Snake defense mechanisms

When threatened, snakes employ various defense mechanisms. Some venomous snakes, like the monocled cobra, can spray venom to deter potential predators.

Other snakes, like the keelbacks, can expand their neck area to appear larger and more threatening.

Many snakes will also bite when cornered, so it’s essential to give them space and avoid provoking them.

Snakebites in Thailand: Prevention and Treatment

Recognizing dangerous snake species

Being able to identify dangerous snake species found in Thailand, such as the king cobra, monocled cobra, and Malayan pit viper, is essential to avoiding potentially harmful encounters. Learning about their habitats and behaviors can help reduce the risk of an accidental bite.

Preventing snake bites

To prevent snake bites, it’s crucial to be cautious when walking through snake habitats, wear protective clothing, and avoid putting your hands or feet in places where snakes might be hiding. Giving snakes a wide berth and respecting their space is the best way to avoid an encounter.

Treating snake bites

In the event of a snake bite, it’s essential to seek immediate medical attention. While waiting for help, keep the affected limb immobilized and at heart level, and try to remain as calm as possible. Do not attempt to suck out the venom, cut the bite wound, or apply a tourniquet, as these actions can worsen the situation.
