The Burmese python (Python bivittatus) is one of the largest species of snakes. It is native to a large area of Southeast Asia and is listed as Vulnerable on the IUCN Red List. Until 2009, it was considered a subspecies of the Indian python, but is now recognized as a distinct species. It is an invasive species in Florida as a result of the pet trade.
The Burmese python is a dark-colored non-venomous snake with many brown blotches bordered by black down the back. In the wild, Burmese pythons typically grow to 5 m (16 ft), while specimens of more than 7 m (23 ft) are unconfirmed. This species is sexually dimorphic in size; females average only slightly longer, but are considerably heavier and bulkier than the males. For example, length-weight comparisons in captive Burmese pythons for individual females have shown: at 3.47 m (11.4 ft) length, a specimen weighed 29 kg (64 lb), a specimen of just over 4 m (13 ft) weighed 36 kg (79 lb), a specimen of 4.5 m (15 ft) weighed 40 kg (88 lb), and a specimen of 5 m (16 ft) weighed 75 kg (165 lb). In comparison, length-weight comparisons for males found: a specimen of 2.8 m (9 ft 2 in) weighed 12 kg (26 lb), 2.97 m (9 ft 9 in... Wikipedia →

About 30% of wildlife watchers report a Burmese Python sighting in Chitwan National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 8 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Burmese Python is recorded against all the reptiles logged in Chitwan National Park (17 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.
