Eastern Copperhead

Agkistrodon contortrixOrder: Squamata, Suborder: Serpentes, Family: Viperidae, Subfamily: Crotalinae, Genus: Agkistrodon, Species: Agkistrodon contortrix

Eastern Copperhead

Venomous Status

Venomous (Solenoglyphous fangs; retractable front fangs characteristic of vipers).

Danger Level

Moderate Risk. While their venom is rarely fatal to healthy adults, the bites are extremely painful and require medical evaluation. They accounts for a high percentage of snakebites in the US.

Geographic Range

Eastern and Central United States, ranging from southern New England south to the Florida Panhandle and west to the Mississippi River and parts of Texas.

Conservation Status

Least Concern (IUCN). Generally abundant, though threatened locally by habitat fragmentation and persecution by humans.

Physical Description

Distinctive 'hourglass' or 'Hershey Kiss' shaped crossbands that are wider on the sides and narrower at the spine. Ground color is tan to pinkish-brown. Triangular head, vertical pupils, and heat-sensing pits between the eye and nostril.

Size & Dimensions

The specimen in the image appears to be a sub-adult or small adult, roughly 24-30 inches. Species average is 24-36 inches (61-91 cm), with a record of 53 inches.

Habitat

Generalist species found in deciduous forests, rocky hillsides, swamp edges, and suburban areas. Prefers microhabitats with leaf litter or debris for camouflage.

Behavior & Temperament

Generally docile and reliant on camouflage. They typically remain motionless when approached. If provoked, they may vibrate their tail (creating a rattle-like sound in dry leaves) and strike defensively.

Diet & Feeding

Carnivorous. Feeds on mice, small birds, lizards, frogs, and large insects (especially cicadas). Uses an ambush strategy, injecting venom and then tracking the scent of the prey.

Reproduction

Ovoviviparous (gives birth to live young). Litters typically range from 1 to 21 young, usually 4-7, born in late summer or early fall.

Venom Profile

Venom Type

Hemotoxic venom, containing metalloproteinases that cause local tissue damage, pain, swelling, and potential necrosis.

Look-alikes

Common Watersnake (Nerodia sipedon) is most often confused but has bands that are widest at the spine. Juveniles resemble Cottonmouths (Agkistrodon piscivorus) but lack the dark eye stripe.

Conservation Status

Least Concern (IUCN). Generally abundant, though threatened locally by habitat fragmentation and persecution by humans.

Cultural Significance

Significant in North American ecology as a predator that controls rodent populations. In culture, it is often a symbol of hidden danger due to its cryptic coloration.

Notable Features

Juveniles possess a bright sulfur-yellow or chartreuse tail tip used for 'caudal luring' to attract frogs or lizards by mimicking a worm.
