Elaphe carinata
A large Elaphe ratsnake of about 2 m from southern China, Taiwan and nearby areas. It eats other snakes and releases a powerful foul-smelling secretion when threatened, hence its Japanese name "stink snake".
The king ratsnake is a large Elaphe found in China (widely, north to Henan, Shaanxi and Gansu), northern Vietnam, Taiwan and Japan (the Senkaku Islands and Yonaguni), in forest, grassland, waterside habitats, farmland and near houses from 100 to 2,500 m. It measures 120 to 250 cm in total length, and females are larger. Two subspecies are recognized: the nominate form and the Yonaguni endemic E. c. yonaguniensis; both Japanese populations are listed as Endangered (EN) on Japan's Ministry of the Environment Red List. Adults of the nominate form are dark brown with yellow or white spots on the forebody, while the Yonaguni form is pale brown and keeps stripes on the rear body as an adult. Juveniles are pale brown with black stripes and crossbars, and the pattern shifts markedly from striped to banded with growth. It constricts rodents, birds and their eggs, lizards, frogs and other snakes, including venomous species. When threatened it hisses, inflates its body and releases a foul-smelling secretion from its vent that can ruin clothing. It is regarded as bad-tempered. Its popularity as a pet is growing, and color mutations such as albinos are being bred.

Carnivore (rodents, birds, eggs, lizards, frogs, snakes)
A powerful snake exceeding 2 m that is active on the ground and in trees; use a large, sturdy, escape-proof enclosure.
Wild animals eat rodents, birds, eggs, lizards, frogs and other snakes; feed rodents in captivity and never house it with other snakes.
It is considered bad-tempered, hissing and inflating when threatened. It often releases a foul, hard-to-remove secretion when picked up.
The pattern changes greatly from juvenile to adult, so do not mistake this for a health problem.
Japanese populations on the Senkakus and Yonaguni are Endangered on the national Red List; avoid collecting or trading wild Japanese animals. Never release a captive animal into the wild.
