Elaphe carinata, known as the King Rat Snake, is a large, non-venomous snake found in forests and grasslands across China and Southeast Asia. It features a robust body with keeled scales, aiding in camouflage. Notable for its aggressive nature, it preys on rodents, birds, and other snakes, playing a crucial role in controlling rodent populations.

Elaphe carinata, commonly known as the king ratsnake or Taiwan stink snake, is native to East Asia. Its geographical distribution includes countries such as China, Taiwan, and Vietnam. It is primarily found in the southern and eastern provinces of China, including Fujian, Guangdong, Guangxi, and Sichuan. In Taiwan, it is widely distributed across the island.

The king ratsnake typically inhabits subtropical and temperate forests, often found in mountainous regions, lowland forests, and occasionally in agricultural areas. The climate in these regions is characterized by warm, humid summers and mild winters, providing a suitable environment for the king ratsnake.

Elaphe carinata occupies a terrestrial ecological niche, primarily feeding on small mammals, birds, and eggs. It is a nocturnal predator, utilizing its keen sense of smell to locate prey. The snake is known for its defensive behavior, producing a strong musk when threatened. It is adaptable to various forested habitats, but prefers areas with dense vegetation and adequate cover.
