Yes, copperheads are venomous snakes. They belong to the Crotalinae subfamily, commonly known as pit vipers, which also includes rattlesnakes and cottonmouths (water moccasins).

Copperheads are named for their copper-coloration, which are often accompanied by a distinctive hourglass-shaped pattern (A. contortrix) or simple large bands (A. laticinctus) on their bodies depending on the species. They are found primarily in the eastern and central regions of the United States.

Although copperhead bites are very serious, they are rarely fatal to healthy adults, but medical attention should be sought immediately.

It is important to exercise caution and avoid handling or disturbing copperheads or any venomous snakes. If you encounter a copperhead in the wild, it is best to maintain a safe distance and allow the snake to move away undisturbed. Taking necessary precautions, such as wearing appropriate footwear and using a flashlight at night when in snake habitats, can help reduce the risk of snake bites.
