The copperhead is a poisonous (venomous) pit viper found in the eastern United States extending as far west as Texas. Copperheads may leave distinctive double marks on the skin. They leave one, two, or three puncture marks on the skin, but you won't always see any marks.
A copperhead has:
Hourglass-shaped markings down the back.
Pit-like depressions behind the nostril.
A triangular head with slit-shaped pupils and fangs.
A single row of plates or scales on the undersurface of the snake, including the tail.
A copperhead does not have rattles but may shake its tail in warning. The snakes can be as long as1.2 m (4 ft).
Symptoms of a bite from a copperhead usually appear from minutes to hours after the bite and include:
Severe, immediate pain with rapid swelling.
Bruising of the skin.
Changes in heart rate or rhythm.
A metallic, rubbery, or minty taste in the mouth.
Numbness or tingling around the mouth, tongue, scalp, feet, or the bite area.
