독사, or the Korean rat snake, is a non-venomous snake commonly found in Korea. It is known for its distinctive black and yellow coloration, which helps it blend into its surroundings. These snakes are primarily active during the day and are often seen in forests, fields, and near water sources. The 독사 plays an important role in the ecosystem by controlling the population of small mammals and insects. They are constrictors, meaning they suffocate their prey before consuming it. Despite their intimidating appearance, 독사 are generally not aggressive and will avoid human contact when possible.
