Agkistrodon Contortrix is a venomous pit viper species found in North America, commonly known as the Copperhead snake. Some of the synonyms for this species include Cenchris contortrix, Agkistrodon atricaudatus, and Ancistrodon contortrix. The name "Copperhead" comes from the snake's distinctive copper-colored head. These snakes are known for their aggressive behavior and venomous bite, which can cause severe pain, swelling, and even death in some cases. Copperhead snakes are often found near wooded areas and are particularly active during the warmer months. It is important to exercise caution when encountering these snakes and to seek medical attention if bitten.
