Crotalus durissus is a venomous pit viper species found in South America. The most widely distributed member of its genus, this species poses a serious medical problem in many parts of its range. Currently, nine subspecies are recognized, including the nominate subspecies described here.
This large Neotropical rattlesnake grows to a length of 1.5 m (4.9 ft), and rarely to a maximum length of 1.9 m (6.2 ft). It has two distinct stripes starting at the base of the head. Within the lines, the color is lighter than the stripes.
Common names for this species include: South American rattlesnake, tropical rattlesnake, neotropical rattlesnake, Guiana rattlesnake (previously used for C. d. dryinus). and in Spanish: víbora de cascabel, cascabel, cascabela, and cascavel. In Suriname it's known as Sakasneki.
C. durissus is found in South America except the Andes Mountains. However, its range is discontinuous, with many isolated populations in northern South America, including Colombia, Venezuela, Guyana, Suriname, French Guiana and northern Brazil. It occurs in Colombia and eastern Brazil to southeastern Peru, Bolivia, Paraguay, Uruguay, and northern Argentina (Catamarca, Córdoba, Corrientes, Chaco, Entre Rios, Formosa, La Pampa, La Rioja, Mendoza, Misiones, San Juan, San Luis, Santa Fe, Santiago del Estero and Tucumán). Also, it occurs on some islands in the Caribbean, including Morro de la Iguana, Tamarindo and Aruba. The type locality given is "America."
