I recently captured some video of a Great Basin Rattlesnake my friend Eric happened upon while we were doing some photography in a desert area of northern Utah. I thought it might be educational and helpful to those who've never heard a rattlesnake give its warning. I was using my zoom lens to allow me to remain at a safe distance while providing a close observation.
This individual was about two and a half feet long and blended in well with its environment. The image below provides a decent view of four important parts of the snake's anatomy--the tongue, pits, eyes, and rattle. The eyes, pits, and tongue help the snake detect prey while the tail is used to deter predators so it does not become the prey.
