The copperhead injects its venom through ducts in its fangs. Its venom disrupts the red blood cells of its prey that in turn becomes completely subdued. Copperhead snakes have jaws that are flexible enough to swallow prey larger than twice its own diameter.pproximately 37 percent of all venomous snake bites are from copperheads. In some states, the percentage of venomous snake bites by the Agkistrodon is much higher. Over a 40-year period in North Carolina, 64 percent of all venomous bites were from the copperhead snake.
