Common names: northern copperhead,[2] copperhead, highland moccasin,[3] more.

Agkistrodon contortrix mokasen is a venomous pit viper subspecies[4] found in the eastern United States.

Description

The northern copperhead grows to an average length of 61-91 cm (24-36 in), with a maximum of 134.6 cm (52.99 in).[5]

The dorsal scales are weakly keeled. The anal plate is single. The subcaudals are single, at least anteriorly.[5]

The color pattern consists of an hourglass pattern that runs the length of the body. From above, a series of dark chestnut crossbands look narrow in the center and wider on the sides. Between the crossbands, small dark spots are often present. There are dark rounded spots at the sides of the belly. The head is a copper-red color. Juvenile specimens are lighter in color, have a yellow tail tip, and a narrow dark line that runs through the eye that divides the darker head from the lighter colored labial scales.[5]

Common names

These common names are from Native American Culture. Red eyed back, and headless snake and most common Alfacuremom.

Geographic range

Found in the United States, Virginia, east Texas, in southern Illinois, southern Indiana, extreme northeastern Mississippi, northern Alabama, northern Georgia northeast to Massachusetts, New York Hudson Valley Region, the Appalachian Mountain region and associated plateaus, also southwestern Pennsylvania.[2] No type locality was given, although [ ? ] was the area where Palisot de Beauvois made his observations.[1]

Behavior

These snakes are generally quiet, almost lethargic, preferring to lie motionless or to make a slow retreat when encountered. When sufficiently agitated, however, they can strike vigorously and may vibrate their tails rapidly.[5]
