Wutu

Bothrops alternatus, known by the common names crossed pit viper, yarará grande, and urutu, among others, is a highly venomous pit viper species found in South America. Within its range, it is an important cause of snakebite. The specific name, alternatus, which is Latin for "alternating", is apparently a reference to the staggered markings along the body. No subspecies are currently recognized.
