Understanding Copperhead Snakes
Characteristics of Copperheads
Copperhead snakes, often confused with non-venomous species like Eastern King Snakes, possess unique characteristics that set them apart. One of the most distinctive features of copperheads is the heat-sensing pit located between their eye and nostril, which is absent in king snakes (NC Parks – Reptile Checklist). This pit allows copperheads to detect the body heat of warm-blooded prey, making them efficient nocturnal hunters.
Copperheads exhibit a copper-toned head and a patterned body that typically ranges from light brown to tan with darker, hourglass-shaped crossbands. They have elliptical pupils, similar to a cat’s, and keeled scales along their bodies.
| Length | Range | Avg. Adult Length |
|---|---|---|
| Juvenile | 18-25 cm (7-10 inches) | — |
| Adult | 61-90 cm (24-36 inches) | 76 cm (30 inches) |
Males generally have longer tails, while females grow slightly larger in body length (National Zoo). Copperheads are also ovoviviparous, meaning they give birth to live young that develop inside the mother’s body.
Habitat and Distribution
Copperheads are widely distributed across the eastern and central United States. Their range extends from the Florida panhandle northward to Massachusetts and westward to Illinois. Copperheads are highly adaptable and can be found in diverse habitats, including:
- Rocky hillsides
- Wetlands
- Forests
- Suburban areas
Interestingly, copperheads are known for their ability to climb into low bushes or trees to hunt for prey. They are also capable swimmers (can copperhead snakes swim), inhabiting semiaquatic environments like wetlands (National Zoo).
