Reticulated python

Malayopython reticulatus

Also calledUlar sawa (Malay) · Sanca kembang (Indonesian) · Ngu lueam งูเหลือม (Thai) · Trăn gấm (Vietnamese)

The world's longest snake, patterned in a net of black, gold and silver-grey. It is non-venomous and kills by constriction. Large individuals take pigs and deer, and a few well-documented cases of people being killed and swallowed are known from Indonesia.

The reticulated python is a python species native to South and Southeast Asia. It is the world's longest snake, and the third heaviest after the green anaconda and Burmese python. It is a non-venomous constrictor and an excellent swimmer that has been reported far out at sea. It has colonized many small islands within its range. Because of its wide distribution, it is listed as least concern on the IUCN Red List. In several countries in its range, it is hunted for its skin, for use in traditional medicine, and for sale as pets. Due to this, it is one of the most economically important reptiles worldwide. Humans, including adults, have occasionally been killed by reticulated pythons, and several well-documented cases involve victims being swallowed wholly or partly. Most recent reported fatal predation cases have occurred in Indonesia, especially on Sulawesi and nearby islands. Wikipedia

§1

What it can do

  1. iReliably measured individuals exceed 6 m, longer than any other snake
  2. iiKills by constriction, stopping blood flow to the prey's heart and brain
  3. iiiSwims well and has colonised many small islands by sea
  4. ivLives in big cities such as Bangkok and Singapore, eating rats in the drains
§2

In the field

Field marks

  • aNet-like (reticulated) pattern of black-edged diamonds on gold or brown, with pale silvery patches along the flanks
  • bThin black line running from the eye back along the head, and a narrow black line along the top of the head
  • cIridescent sheen; orange or amber eyes
  • dHeat-sensing pits in the lip scales
Not to be confused with
The Burmese python (Python bivittatus) has large dark blotches and a pale arrowhead mark on the top of its head instead of a thin black line, and is heavier for its length. Blood pythons (Python brongersmai) are short and very stout.
Where to see it
Rainforests and towns of Malaysia, Borneo, Sumatra and Thailand; Singapore's Sungei Buloh and Bukit Timah; often seen at night by rivers

Life & habits

Diet
Mammals and birds, from rats and chickens to pigs, monkeys and deer
Habitat
Rainforest, woodland, swamps, plantations and urban drains near water
Size
Commonly 3–6 m; exceptionally over 7 m
Lifespan
~20–30 years in captivity

An ambush hunter that lies hidden near water or game trails. Females coil around their eggs and twitch their muscles to keep them warm. It is not venomous; serious attacks on people are very rare and usually involve very large snakes.

Marginalia

Johann Gottlob Schneider described it as Boa reticulata in 1801. Hundreds of thousands of skins are still exported from Indonesia and Malaysia for luxury leather under CITES quotas.

Curiosity

The longest snake ever kept in captivity was a reticulated python called Medusa in Kansas City, measured at 7.67 m in 2011.
