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.
