Reticulated python

The reticulated python (Malayopython reticulatus) is a large snake that lives in South and Southeast Asia. It is known as the world's longest snake and is the third heaviest after the green anaconda and Burmese python. This snake is not poisonous but catches its prey by wrapping around it tightly, which is called being a constrictor. It is also very good at swimming and has been seen far out in the ocean.

Because this python lives in many places, it is considered least concern on the IUCN Red List, meaning it is not in danger of disappearing. However, people sometimes hunt it for its skin, for use in traditional medicine, and to sell as pets. This makes the reticulated python very important to many economies around the world.

Sadly, there have been cases where adult humans have been hurt by these snakes in the wild, mostly on the island of Sulawesi. Even though this happens, the reticulated python is still an amazing and important animal in nature.

Taxonomy

The reticulated python was first described in 1801 by a scientist named Johann Gottlob Theaenus Schneider. He looked at two snakes in a museum and thought they were different species because they looked slightly different in color and pattern. The name "reticulatus" means "net-like" in Latin, which describes the snake’s complex pattern.

Later scientists studied the snake’s genes and found it was closely related to pythons from Australia and Papua. Some people suggested calling it by a different name, Broghammerus, but most scientists today use the name Malayopython, which was proposed in 2014. This name is now widely accepted.

Subspecies

Three subspecies of the reticulated python have been proposed:

• M. r. reticulatus – the Asian reticulated python
• M. r. jampeanus – the Kayaudi reticulated python or Tanahjampean reticulated python, found on Tanahjampea in the Selayar Archipelago south of Sulawesi. This subspecies is smaller, usually not growing much longer than 2 meters (about 6 feet 7 inches).
• M. r. saputrai – the Selayer reticulated python, found on Selayar Island in the Selayar Archipelago and nearby Sulawesi. This subspecies is also smaller, usually not growing longer than 4 meters (about 13 feet 1 inch).

The other two subspecies mentioned are considered dwarf forms. There may be another small subspecies on the Sangihe Islands north of Sulawesi, but it has not yet been formally described. Several other proposed subspecies have not been widely accepted by scientists.

Characteristics

The reticulated python has smooth scales arranged in rows along its back. It is the largest snake found in Asia. Studies of many wild pythons in places like Sumatra show they can range from about 1.5 meters to over 6 meters long, though very long ones over 6 meters are rare. According to the Guinness Book of World Records, it is the only snake that regularly grows longer than 6 meters.

One of the largest measured pythons was found in Indonesia, measuring nearly 7 meters long and weighing about 59 kilograms. While some reports claimed even larger snakes, scientists need careful measurements to confirm such records. The snake's pattern helps it blend into its jungle home, making it hard to spot. Some zoo snakes have been reported to be very long, but measuring a living python is tricky because of its size and strength.

Distribution and habitat

The reticulated python lives in South and Southeast Asia, including places like the Nicobar Islands, India, Bangladesh, and many other areas. It prefers rainforests, woodlands, and grasslands near water, such as rivers, streams, and lakes. These snakes are excellent swimmers and have even been seen far out at sea, which helps them live on many small islands. In the early 1900s, they were often seen in busy parts of Bangkok and sometimes ate domestic animals.

Behaviour and ecology

Diet

The reticulated python waits for animals to come close, then wraps them in its coils to hold them tight. It eats mammals and sometimes birds. Smaller pythons eat small animals like rats and bats, while bigger ones can eat larger animals like wild boar and deer. These snakes can even swallow prey as big as a quarter of their own body length. Near places where people live, they might try to catch chickens, cats, or dogs. One big python was known to have eaten a sun bear, which took over ten weeks to digest.

Reproduction

The reticulated python lays eggs. Adult females lay between 15 and 80 eggs at a time. The eggs take about 88 days to hatch when kept at the right temperature. Baby pythons are at least 0.61 metres (2 feet) long when they hatch.

Danger to humans

The reticulated python is one of the few snakes known to attack humans. There are rare reports of these snakes eating people, mostly in places where they live naturally. While attacks on humans in captivity are uncommon, wild pythons have been known to sometimes attack humans in areas like Sulawesi, Indonesia.

Because of their size, a full-grown reticulated python could potentially open its mouth wide enough to swallow a human. However, the width of a human's shoulders can sometimes make this difficult even for very large snakes. There have been several documented cases where people were attacked or eaten by these snakes, mostly in Southeast Asia.

In captivity

The reticulated python has become more popular as a pet because of efforts to breed them in captivity. Breeders have created different colored pythons, such as "albino" and "tiger" strains, as well as others like "sunfire" and "motley". However, some color changes, like the "BEL" mutation, can cause health problems in the snakes when they grow up.

Smaller versions of these pythons, found on certain islands, are also popular because they stay much smaller than those from the mainland. These smaller pythons are often kept as pets, but people should have experience handling large snakes to stay safe. Even though these snakes are beautiful, they can sometimes bite or wrap around something if they feel scared, which can cause injuries.
