Reticulated Python
Malayopython reticulatus · also called retic
The reticulated python is the longest snake alive — a slender, patterned constrictor that grows past six metres, swims between islands, and lives so close to people across Southeast Asia that it has become a fixture of village life, drainage canals, and oil-palm plantations.
Overview
Reticulated pythons occupy a wide range of habitats — rainforest, woodland, grassland, river margins, mangroves — and are especially common in disturbed, human-modified landscapes where rats are abundant. The “reticulated” name comes from the intricate net-like pattern of diamonds and lines along the back, which is superb camouflage in leaf litter and dappled light.
Physical characteristics
Most adults are 4–6 m long; females grow considerably larger than males. The longest reliably measured wild snake was 6.95 m; claims of much larger animals, including a famous 10-metre report, have never been verified and are almost certainly exaggerations of stretched skins.
The head is relatively small and arrow-shaped, with heat-sensing pits along the lips that let the snake detect the body warmth of prey in complete darkness. The teeth are long, recurved, and made for holding, not chewing.
Hunting and feeding
The reticulated python is an ambush predator. It lies coiled beside a game trail, a burrow entrance, or a water margin and strikes when prey passes within range, grabbing hold and instantly wrapping it in coils. Contrary to the popular image, constriction does not crush or suffocate — the pressure collapses the prey’s blood vessels and stops the heart within a couple of minutes.
Diet scales with size. Small pythons eat rodents and lizards; large ones take monkeys, wild pigs, deer, and, near settlements, dogs, goats, and poultry. After a big meal a python can go months without eating.
Reproduction and life cycle
A female lays a clutch of 15 to 80 leathery eggs and then does something few snakes do: she coils tightly around them and stays for the roughly two- to three-month incubation, “shivering” her muscles to generate heat and keep the clutch a few degrees warmer than the surrounding air. She leaves shortly before the eggs hatch. Hatchlings are about 60 cm long and completely independent.
People and pythons
The reticulated python has one of the largest reptile-skin trades in the world — several hundred thousand to over a million skins a year are exported for fashion leather, mostly from Indonesia and Malaysia. Remarkably, the species seems to withstand it: it breeds prolifically, thrives in farmland, and remains common. It is listed as Least Concern, and the main conservation questions are about making the skin trade sustainable and traceable, and about reducing the number of large pythons killed out of fear when they turn up near homes.
Reticulated Python: common questions
What is the longest snake in the world?
The reticulated python. Reliable records reach nearly 7 metres, and the longest verified specimen measured 6.95 m. It is longer, though much lighter, than the green anaconda, which is the heaviest snake.
Do reticulated pythons eat people?
It is very rare, but it does happen. There are a small number of well-documented cases from rural Indonesia and the Philippines of large reticulated pythons killing and swallowing adult humans. The overwhelming majority of pythons never grow large enough or bold enough to attempt it.
Are reticulated pythons venomous?
No. Like all pythons and boas, the reticulated python is a constrictor. It seizes prey with backward-curving teeth, throws coils around it, and tightens with each of the animal's exhalations until circulation stops. Then it swallows the prey whole, head first.
How do reticulated pythons reach small islands?
They swim. Reticulated pythons are powerful swimmers and have colonised many small islands off the Southeast Asian coast under their own power, sometimes crossing several kilometres of open sea.
