## Summary

Bothrops jararaca—known as the jararaca or yarara—is a highly venomous pit viper species endemic to South America in southern Brazil, Paraguay, and northern Argentina. The specific name, jararaca, is derived from Old Tupi îararaka. Within its geographic range, it is often abundant and is an important cause of snakebite. No subspecies are currently recognized.
The drugs known as angiotensin converting enzyme (ACE) inhibitors, used for the treatment of hypertension and some types of congestive heart failure, were developed from a peptide found in the venom of this species.
