In this video segment from Wild Nevada, host Brian Wignall and herpetologist Alex Heindl discuss three species of rattlesnake found in the southwestern U.S. The video describes rattlesnake behavior and explains how the rattle, its most distinctive feature, is made from shed skin. We also learn details about the rattlesnake's dangerous bite, including when and why the snake strikes, as well as its ability to control the amount of venom a bite contains.
