The Korean rat snake is a non-venomous snake native to the Korean Peninsula and parts of China and Japan. It typically grows to a length of 1.2 to 2.4 meters and is known for its distinctive coloration, which can range from yellow to gray with dark blotches. This snake is primarily terrestrial and is often found in forests, grasslands, and agricultural areas. Korean rat snakes are excellent climbers and are often seen in trees. They primarily feed on small mammals, birds, and eggs, using their constricting method to subdue prey. These snakes are also popular in the pet trade due to their docile nature and striking appearance.
