Copperhead is a common name for the venomous North American snake species *Agkistrodon contortrix*, a pit viper found in the eastern and south-central United States. It is known for its copper-coloured head and hourglass-shaped body bands. The species is not native to Canada, but may be encountered in zoological education or comparison with Canadian snakes.
Description
Copperheads are medium-sized, heavy-bodied snakes with a copper-coloured head, tan to grey body, and dark hourglass-shaped markings. Their facial pits and vertical pupils are typical features of pit vipers.
Distribution and habitat
The species occurs in the eastern and south-central United States, including wooded, rocky, and semi-aquatic habitats. Local range details vary by subspecies and state.
Behaviour and diet
Copperheads are carnivorous ambush predators that feed on small animals. Their camouflage helps them remain hidden on the forest floor, and they often rely on stillness rather than active pursuit.
Venom and human significance
Copperheads are venomous, but bites are rarely fatal with appropriate medical care. They are important in public education because they are frequently encountered near human activity in some parts of their range.
