Burmese Python
Massive python of Myanmar and Thailand — invasive population in the Everglades.
By the WARN Research & Conservation TeamChecked against IUCN Red List & CITES sourcesLast updated
In brief
The Burmese Python is a massive constrictor native to Myanmar, Thailand, Vietnam and southern China — with an invasive breeding population in Florida's Everglades devastating native mammals. Its defining trait is rapid growth to 4–5 m and voracious appetite. Wild Asian populations face skin trade and hunting pressure.
Burmese Python: At a Glance
| Origin | South-east Asia |
|---|---|
| Size | Very large (4–5 m) |
| Typical length | 3.5–5 m (11–16 ft) typical adult length; 30–70 kg body mass in large females |
| Lifespan | 10–30 years depending on species |
| Scales & pattern | Tan or brown ground with dark brown dorsal blotches bordered in black; arrow-shaped head marking. Smooth iridescent scales. Albino and granite morphs popular in captivity. Pattern darkens with age. Healthy specimens shed in one piece; frequent incomplete sheds indicate humidity or health problems. |
| Temperament | Powerful constrictor, invasive in Florida |
| Conservation note | Expert reptile keepers only — Burmese pythons grow too large and powerful for most homes. Secure room-sized enclosures with multiple handlers for maintenance are essential. Never release unwanted pets — Florida's invasive crisis demonstrates the ecological damage. Captive-bred only. |
History & Origins
Burmese pythons inhabit rainforest, grassland and mangrove edge from Myanmar through Thailand, Laos, Vietnam, Cambodia and southern China. They are excellent swimmers and often found near water. Escaped and deliberately released pets established a breeding population in Florida's Everglades from the 1980s onward, where they consume deer, raccoons and bobcats — among the most damaging invasive reptiles in North America. Wild Asian populations face skin trade pressure and hunting for meat and traditional medicine. CITES Appendix II listing regulates international trade. Burmese pythons can live 20 to 25 years in captivity and grow from hatchling to 3 m within three years with regular feeding — enclosure planning must anticipate adult size from day one.
Burmese Python Fun Facts
- Burmese pythons in Florida's Everglades have consumed alligators — documented predation both directions.
- They can swim long distances and survive in saline mangrove edge habitat.
- A single female may produce 50 to 100 eggs in a clutch — among the largest clutches of any python.
- Florida's invasive population likely began from Hurricane Andrew destroying a breeding facility in 1992.
Burmese Python Common Health Issues
Conditions seen more often in this breed, and how owners and vets help manage them. This is general guidance, not veterinary advice — always speak to your vet.
Invasive impact (Florida)
Released Burmese pythons in the Everglades consume native mammals, birds and reptiles, causing documented population crashes of raccoons, opossums and bobcats.
Care: Never release unwanted pets. Rehome through reptile rescue organisations or humane euthanasia as last resort.
Skin trade
Wild Burmese pythons are hunted for leather in South-east Asia under CITES quotas, with laundering of illegally sourced skin.
Care: Purchase captive-bred animals only. Avoid python skin products of uncertain origin.
Habitat loss
Rainforest clearing in Myanmar and Thailand reduces Burmese python range and prey availability.
Care: Support habitat protection in South-east Asia. In captivity, provide adequate space and thermal gradients throughout life.
Snakes keep ecosystems healthy
Snakes control rodents and serve as prey for raptors — yet persecution and habitat loss remove them silently. WARN publishes these guides to reduce fear-driven killing in Pakistan, Brazil, Colombia and beyond.
