The Bothrops genus is responsible for more than 95% of ophidian accidents in Argentina, most of these are reported in the Northeast and Northwest provinces. Bothrops alternatus, is the most frequent species of the genus Bothrops (yarará), themost southern large-scale viperid in the world and one of the most important species in Argentina, being able to be found in rela-tion to urban nucleus. Their characteristic features are kidney-like figures in the skin, that mimic phone tubes or beans, completeor incomplete, until the merged form. It presents a loreal pit, thermoreceptor organ located between the eye and the nostril. Itsdentition is solenoglyphous, hollow inoculating teeth, with closed duct, fixed to a mobile maxillary bone. Although variationsbetween animals are described, it is considered a monotypic species. The identification of this snake is important due their abun-dance in around urban regions and its frequency of finding.

Keywords : Yarará; Bothrops alternatus; Viper.
