How to Identify the Timor Python (Identification Guide)

The Timor Python (Malayopython timoriensis) is a slender, non-venomous python from the Lesser Sunda Islands of Indonesia. Once grouped with the reticulated python, it is now placed with its relatives in Malayopython. This guide describes how to recognize it visually.

Key identifying features

Look for a moderately sized, slim python with a pattern of dark-edged blotches over a tan to olive ground, and a strongly iridescent sheen in sunlight. Adults are typically 1.8 to 3 meters, more slender than the bulky short-tailed pythons. The head is elongate and clearly distinct from the neck. Its combination of medium size, netted pattern, iridescence, and island distribution helps place it.

Coloration & pattern

The body is tan, olive-brown, or grayish, marked with a series of darker blotches and a broken, net-like or diamond pattern along the back and flanks. The pattern is reminiscent of a smaller, subtler version of the reticulated python's netting, reflecting their relationship. The scales are smooth and glossy, throwing a marked rainbow iridescence. The belly is pale yellowish or cream. Some individuals show yellowish or greenish highlights along the sides.

Head, eyes & scales

The head is long and narrow with a somewhat pointed snout and is distinctly set off from the neck. Eyes are medium-sized with vertical pupils. Labial heat-sensing pits line the jaws. There is often a dark line running from the eye toward the angle of the jaw, and sometimes a dark middorsal line on the head. Dorsal scales are smooth and highly iridescent.

Size & body shape

The Timor Python is a slender, agile python compared with the stout short-tailed species. Its body is relatively long for its girth, and the tail is moderately long and prehensile, reflecting semi-arboreal habits. This lithe build, together with the netted pattern, distinguishes it from the heavy-bodied pythons of the region.

Range & habitat

The species occurs in the Lesser Sunda Islands, including Flores and nearby islands, in a range of habitats from forest and scrub to grassland and cultivated areas. It is agile and partly arboreal, and is often found in disturbed and edge habitats.

How to tell it apart from look-alikes

The Timor Python is smaller and more subtly patterned than the true Reticulated Python, and its range is restricted to the Lesser Sundas, where the giant reticulated python is generally absent. Its slim build separates it from the stout short-tailed pythons, and its netted, iridescent pattern separates it from plainer species like the Papuan Python. Within its island range, a slender, medium-sized python with a broken net-like pattern and strong sheen is most likely the Timor Python. When comparing with the reticulated python, note that the Timor Python's netting tends to be less regular and less complete, and its overall build is proportionally lighter. The elongate head with a dark eye-stripe, the moderate size, and the restriction to the Lesser Sunda Islands together provide a reliable identification. Its semi-arboreal, agile habits and frequent presence in disturbed and edge habitats also fit the species and can serve as supporting contextual clues.
