The Indo-Chinese Rat Snake (Ptyas korros) is a large, slender, and fast-moving snake found across Southeast Asia, including Thailand, Cambodia, Vietnam, and parts of Indonesia. It has a brown or olive dorsal coloration with a lighter underside, and juveniles often display faint crossbars. This species is diurnal and highly active, frequently encountered in agricultural areas, forests, and near human settlements where it hunts for rodents, frogs, and small birds.
