Species Description

A small species which can be found in high elevation pine-oak habitat along the Transverse Volcanic Cordillera. The Central Plateau dusky rattlesnake has a generalist diet consisting of frogs, small mammals, lizards, and invertebrates.

Females give live birth to moderate sized litters of 7 babies on average.

Fun fact: The venom of this species has shown to have antibacterial and antimicrobial properties, potentially leading to future research and treatments using its venom! This is especially important as many diseases become more resistant to current treatments. Venom saves lives!
