The Bothrops alternatus, known as yarará in Argentina, is a life-threatening venomous snake of the warm and humid regions of South America. It belongs to the genus Bothrops and the family Viperidae. It is found found in Brazil, Paraguay, Argentina, and Uruguay. It can also be encountered in Venezuela.
The glands of Bothrops alternatus secretes cytotoxic venom, which destroys the tissue around the bitten area. This causes severely necrotized tissues (gangrene). Thus, there have been many cases in which amputation of the hand or foot was required in order to avoid septicemia (blood-poisoning).
