Adults weigh between 0.5 and 1.5 kg. Body length ranges from 1.5 to 2.5 m, occasionally reaching 2.7 m, making it one of the largest snakes of its genus. The thin-tailed rat snake is a diurnal species, active mainly during the day. It is both terrestrial and arboreal, with excellent climbing skills. Breeding occurs in spring, and females lay 5–15 eggs, which hatch after about 60 days. Hatchlings are independent from birth. A carnivorous predator feeding mainly on rodents, birds, lizards, and eggs. It can be beneficial to humans by controlling rodent populations.
The genus Orthriophis evolved from non-venomous Asian colubrids in the Late Miocene, around 10 million years ago. In many Asian cultures, this snake symbolises fertility and domestic protection. In Chinese folklore, it is associated with harmony and natural balance. Due to its calm nature, it is also kept as a pet in terrariums.
According to the International Union for Conservation of Nature (IUCN), Orthriophis taeniurus is classified as Least Concern. Populations are stable, though habitat loss and collection for the pet trade pose local threats.
