Family: Pythonidae. Large powerful constrictors reaching maximum lengths of 3-10 m. Three specimens are known to occur in northern Thailand.

Malayopython (Broghammerus/Python) reticulatus, the Reticulated Python.
Characteristic pattern with zigzags and elliptic white dots, yellow head. Widely distributed in northern Thailand. Specimens of more than 7 m length have been reported. A. A large, about 4 m long specimen in captivity at Wat Mae Kampong, Mae On Village, Mae On District Chiang Mai. Pythons often rest in positions similar to this “noodle ball”. B.

Python molurus (bivattus), the Burmese or Indian Python. Sharp V-shaped mark on the upper side of the head. The species occurs throughout northern Thailand, but is somewhat less common than the Reticulated Python. A-B: Juvenile from Mueang District, Chaiyaphum (Northeast-Thailand).

Python brongersmai, the Short or Blood Python, has not been illustrated here. In northern Thailand this rare species has only been reported from the very south of the Lower North.
