Terciopelo is a highly venomous species of pit viper found at low to moderate elevations in northeast Mexico and Central America, and into South America where it is known from elevations up to 2600 meters in the Colombian and Ecuadorian Andes, as well as into Venezuela. With a mass of up to 6 kilograms (13 lb) and a maximal length of 2.5 metres (8.2 ft), the terciopelo is among the largest pit vipers. It is light to dark brown in color, often with yellow zig-zag-shaped lines on each side of the body. Dubbed "the ultimate pit-viper" for its large size, fangs and venom yield, it has a fearsome reputation, responsible for the most snakebites within its range because of its defensive temperament and proximity to human residence. However, like other venomous snakes, it avoids confrontation with humans whenever possible. No subspecies are currently recognized.
