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 →

No species of the same family or order lives in Cat Tien National Park, so these are its closest relatives here: other reptiles.
Possible
About 20% of wildlife watchers report a Reticulated Python sighting in Cat Tien National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 26th most-seen of the 45 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a Reticulated Python in Cat Tien National Park on a given day, against under 5% in March–May, July and October–January, the lowest months. That is one of Cat Tien National Park's wettest months, with about 340 mm of rain against 15 mm in February.
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.
3rd of 10
Of the 10 parks where we can rate Reticulated Python sightings, Cat Tien National Park ranks 3rd at about 20%. The best odds are in Khao Sok National Park (Thailand, about 30%) and Tangkoko Nature Reserve (Indonesia, about 30%).
GBIF citizen-science records
It is estimated from how often the Reticulated Python is recorded against all the reptiles logged in Cat Tien National Park (12 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.
