Just a quick note here to clear something up. We get some searches for people looking for anacondas in Thailand – Bangkok, Phuket, Chiang Mai, Pattaya.
There are no anacondas in the country of Thailand. At least not natively. There are PYTHONS here.
We have mostly reticulated pythons, but then there are also Burmese pythons and Blood pythons.
Reticulated pythons get as long as an anaconda, but not as thickly muscled, nor do they weigh as much. The biggest reticulated python I’ve seen in the country was about 6.5 meters (21.3 feet). Supposedly they reach 30 feet.
