141 | Everything Mohave Rattlesnakes

Dr. Jenkins sits down with rattlesnake expert Mike Cardwell for a deep dive into one of North America’s most fascinating and misunderstood species—the Mohave Rattlesnake. Mike’s path is anything but ordinary: a childhood passion for snakes led to a 30-year career in law enforcement, before he returned to science to study rattlesnakes full-time. Together, they explore the natural history of the Mohave Rattlesnake—where they live, what they eat, how they move, and how they reproduce. The conversation then turns to one of the most intriguing aspects of the species: venom. Mike explains how venom characteristics vary across their range and shares key findings from his own studies on populations with dramatically different venom types. They wrap up by diving into his book on Mohave Rattlesnakes as well as what new discoveries will appear in the upcoming second edition. This episode blends science, storytelling, and personal journey—you won’t want to miss it!
