Species Description

This large rattlesnake can be found in Central American from Mexico to Costa Rica. It largely inhabits semiarid dry tropical forests and scrub forests. The Latin translation for "simus" is "flat-nosed."

Fun Fact: A neonate Central American rattlesnake shares only 50% of the same venom proteome with an adult and includes more neurotoxic proteins.
