Reptiles and Amphibians of Bangkok

Central Thailand's Snakes, Lizards, Turtles, and Frogs

Identifying Lizards

Lizards are the most common reptiles in Bangkok, and are a big part of natural pest control. There are house geckos eating flies and mosquitoes in our rooms, Tokays munching on mice and cockroaches on the roofs, skinks and garden lizards hunting down garden pests, and monitors cleaning up carrion. Bangkok would be a dirtier and more diseased place without its lizard populations.

Geckos – soft lizards on the walls

Geckos have soft skin, large eyes, and famously run up and down the city’s walls. Geckos are usually seen at night, but can be found during the day inside darker areas. The following geckos are found in Bangkok:

Flat-tail House Gecko Hemidactylus platyrus
Flat-tailed House Gecko – flat tail with no spines, eyestripe is dark if present
Spiny-tail House Gecko Hemidactylus frenatus
Spiny-tailed House Gecko – spines on round tail, eyestripe is light if it is present

Long-tailed Grass Lizard Takydromus sexlineatus

Agamas – spiny lizards in the bushes

Agamas have rough scales and often have a small crest going down their neck. They are active during the day and are often seen on trees or other vegetation. These agamas are found in Bangkok:

Oriental Garden Lizard Calotes versicolor

  1. I live on the outskirts of Bangkok (Samut Prakan) and very often here a small animal, but never see one. I am not sure of the spelling but sounds like tuckare. Maybe they get the name from the sound of their call which sounds like their name. Would you have a photo of this animal?

  2. Yesterday i went out at night with the flashlight searching for reptiles in a backyard of my condo, and found an Oriental Garden Lizard sleeping on a branch of a bush. It’s eyes wasn’t closed, but it let me come really close to make a shot.

  3. I have a video of one I didn’t see in your list, at least which I recognized. Email me back if you would like it. Little guy has an extremely long tail, and almost appeared to walk on his hind legs. Didn’t get to video him in motion, regrettably.

  4. Thks for this. It helped my curiosity with the skink, agama, gecko I find in my area in the hills north east of saraburi province. Also i.d.’d 2 kinds of wolf snakes here. Seen and took pics of water monitor lizard in Samut Prakarn.
