Class: Reptilia
Order: Squamata
Family: Colubridae
Genus: Orthriophis
Species: Orthriophis taeniurus
Subspecies: Orthriophis taeniurus ridleyi
Found in Southeast Asia, including Malaysia, Thailand, and Sumatra (Indonesia). Prefers humid tropical forests, but can also be seen near plantations and human settlements. Lifespan in the wild – 10–15 years, in captivity: up to 20 years with proper care. Ranges from 1.5 to 3 kg, depending on age and sex. Body length 1.8–2.4 m, occasionally up to 2.6 m. The snake has a slender body and long tail, which gives it its name.
A diurnal and semi-arboreal species. The breeding season occurs in spring, when females lay 6–12 eggs. Incubation lasts 60–80 days. Hatchlings are independent from birth. Usually solitary, but can gather where prey is abundant. Primarily carnivorous, feeding on small mammals (especially rats), birds, and occasionally lizards or eggs. Plays a key role in rodent population control.
The genus Orthriophis evolved in Asia around 25–30 million years ago. The subspecies O. t. ridleyi adapted to humid tropical ecosystems of Southeast Asia.
In local folklore, the species is considered beneficial, controlling pests. Named after Henry Nicholas Ridley, the British naturalist who studied the fauna of Malaysia. It is popular among herpetologists and educators due to its striking colouration and behaviour.
According to the IUCN Red List, Orthriophis taeniurus is classified as Least Concern. Main threats include habitat loss and illegal collection for the pet trade.
