Thailand’s 3 Very Common Venomous Snakes
Thailand has approximately 60 snake species that are considered venomous and potentially dangerous to human beings. Below are photos, videos, and links to more information on some of the most common snakes that fit this description.
Calloselasma rhodostoma. Malayan Pit Viper.
Very dangerous. Potentially deadly. This snake is active at night (nocturnal) and during dawn and dusk (crepuscular) and during rainy or very overcast weather. I have found them in the lowlands at sea level, and as high as 500 meters here in Thailand.

The following is a video showing the color variations for the Malayan pit viper. These are all from Southern Thailand, so depending where you are in the country, yours may look similar or slightly different. The very triangle head shape and triangle pattern on the top back will not change.

Naja kaouthia. Monocled Cobra.
Very dangerous and potentially deadly. This snake is most active during the daytime, but is also sometimes found to be active at night. During some of the hottest days they can be seen regularly crossing the roads. Around 3 pm. seems to be a very active time for them.

Rhabdophis subminiatus. Red-necked Keelback.
This colorful snake was often kept as a pet and hand-held before it was realized they pack a deadly bite. Their venom is as strong as a banded krait on the LD scale. They are active during daylight hours and are commonly found across Thailand.
Keep in mind, the smaller the snake, generally the more quickly it can strike.
