The reticulated python (Malayopython reticulatus) is a python species native to South and Southeast Asia. It is the world's longest snake, and the third heaviest after the green anaconda and Burmese python. It is a non-venomous constrictor and an excellent swimmer that has been reported far out at sea. It has colonized many small islands within its range. Because of its wide distribution, it is listed as least concern on the IUCN Red List. In several countries in its range, it is hunted for its skin, for use in traditional medicine, and for sale as pets. Due to this, it is one of the most economically important reptiles worldwide. Humans, including adults, have occasionally been killed by reticulated pythons, and several well-documented cases involve victims being swallowed wholly or partly. Most recent reported fatal predation cases have occurred in Indonesia, especially on Sulawesi and nearby islands.
The reticulated python was first described in 1801 by Johann Gottlob Theaenus Schneider, who described two zoological specimens held by the Göttingen Museum in 1801 that differed slightly in colour and pattern as separate species, Boa reticulata and Boa rhombeata. The... Wikipedia →

Possible
About 20% of wildlife watchers report a Reticulated Python sighting in Gunung Leuser National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 25th most-seen of the 47 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March, August and November
In those months about 30% of wildlife watchers report a Reticulated Python in Gunung Leuser National Park on a given day, against under 5% in February, May, September–October and December, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Reticulated Python sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
5th of 10
Of the 10 parks where we can rate Reticulated Python sightings, Gunung Leuser National Park ranks 5th at about 20%. The best odds are in Khao Sok National Park (Thailand, about 30%), Tangkoko Nature Reserve (Indonesia, about 30%) and Cat Tien National Park (Vietnam, about 20%).
GBIF citizen-science records
It is estimated from how often the Reticulated Python is recorded against all the reptiles logged in Gunung Leuser National Park (9 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
