Interesting Facts:

Rattlers shed their skin 3 or 4 times per year on average, so it is unusual to see more than 12 rattles. The "pit" is a temperature-sensitive structure on the side of their head used to locate warm-blooded prey. Rattlers can climb trees. It is not uncommon to find one 4 - 5 feet off the ground in mesquite, manzanita or other shrubs. They are also good swimmers. The fangs can be folded back inside a skin fold to protect them when their mouth is closed. The rattlesnake is the only venomous snake in Utah. There are four species and three subspecies (western rattlesnake) in the state.
