Head to head
Burmese Python vs Reticulated Python
These are two of the largest snakes on Earth, they overlap across Southeast Asia, and they are often confused. The Burmese python is a massive, heavy-bodied snake with a giraffe-like pattern of brown blotches. The reticulated python is longer, the longest snake in the world, more slender, and marked with an intricate net-like geometry. Both are constrictors, both lay eggs, and both are kept by experienced keepers, but the reticulated python is the more formidable animal.
| Burmese Python | Reticulated Python | |
|---|---|---|
| Scientific name | Python bivittatus | Malayopython reticulatus |
| Typical adult length | 3.5 to 5.5 m | 4 to 6.5 m; historical claims run higher |
| Build | Very heavy and thick for its length | Long and comparatively slender but strong |
| Pattern | Large brown blotches with an arrowhead on the head | Fine black net over gold, grey, and cream |
| Range | South and Southeast Asia | Southeast Asia, far out into the islands |
| Notable status | Invasive and established in the Florida Everglades | Heavily harvested for the skin trade |
| Temperament | Often calmer; still dangerous at size | Alert, food-driven; implicated in human deaths |
| Conservation status | Vulnerable | Least Concern |
Burmese Python vs Reticulated Python: common questions
Which is bigger, a Burmese or a reticulated python?
It depends on what you mean by bigger. The reticulated python is longer, and it is the longest snake species in the world, with well-documented individuals over 6.5 metres and reliable historical records approaching 7. The Burmese python is shorter on average but much heavier-bodied, so a large Burmese can outweigh a reticulated python of the same length. In terms of sheer mass the green anaconda still beats both. Claims of pythons over 8 or 9 metres are almost always exaggerations of stretched skins or rough estimates.
Why are Burmese pythons a problem in Florida?
Escaped and released pets established a breeding population in the Everglades in the late twentieth century, and the subtropical wetland turned out to suit them almost perfectly. With no natural predators and abundant prey, the population exploded, and surveys have linked it to steep declines in raccoons, opossums, rabbits, bobcats, and wading birds across large parts of the park. The snakes are cryptic and hard to find, so control relies on hired hunters, detector dogs, and tracking radio-tagged males to breeding aggregations. The reticulated python has not established there in the same way.
Are these snakes dangerous to humans?
Both are large enough to be genuinely dangerous, and both kill by constriction rather than venom. The reticulated python is the one with a clear record of preying on people: there are several confirmed cases from rural Indonesia and the Philippines of adults being killed and swallowed. Burmese python attacks on humans are far rarer and usually involve captive animals and feeding accidents. For any constrictor over about 3 metres, standard safety practice is never to handle or feed it alone, because the risk is a coil around the neck, not a bite.
